Philological boilerplate plus Unicode crib sheet
Àjàyí Crowther's orthographic subdot, adopted in 1851 to signify the systematic phonetic feature [+ narrow pharynx] — better known after Chomsky & Halle (1968) as [ATR] — is an essential piece of tech for tens of millions of 9ja literates. In principle, it can be digitally rendered as the Unicode glyph U+0329 ("combining vertical line below" = HTML "& # 8 0 9 ;" (without the wordspaces), or alternatively as U+0323 ("combining dot below") = HTML "& # 8 0 3 ;" (without the wordspaces), but in practice this patch leaves a lot to be desired. For one thing, not all browsers display the subdot, so some readers of this page will see nothing under the first two vowels of É̩hu̩gbò. For another, the kerning (horizontal alignment) of this kludge is chaotic, especially in book‑quality faces in sizes above 8 pt. Even in certain typefaces wishfully called "Unicode compliant", legibility is woeful as can be verified by inspection of the enclosed test page, which was prepared at random. (Real published examples can be much worse.) "Precomposed [and simultaneously subdotted] accented characters for Yorùbá were rejected from Unicode" (Filip Blažek), but why exactly? Polite inquiries to The Unicode Consortium about this unsatisfactory status quo were replied (email of M.D., 25 September 2008, available on request) with a smooth blend of bureaucratic indifference ("The disclaimer you mentionned [sic] in your email *is* absolute, and these combinations will not be encoded, so you should not waste your time making a proposal for them") and lazy palming off of the problem to apocalyptic and politically radioactive SIL/WBT missionaries, who are assumed to 'own' subdotted roman scripts, maybe based on an implied metaphysical 'ownership' of the speakers of the respective languages: "Those look fine with a font like Doulos SIL that can handle them". Funny enough, δοῦλος/doulos is New Testament Greek for 'slave'—the kids at Camp Wisdom must have been dreaming of Sigmund Freud when they named their Africanist digital type. Such self-outing nightmares aside, anyone who thinks that pentacostal interventions are harmless has not observed the condition of civil society in evangelized West Africa of recent decades. This typographic nicety nicely illustrates how priorities are set, who benefits and so on, under globalized neoliberalism. Not to excuse the Abuja ruling elite, who could have taken a benevolent interest in the problem, whereas the opposite has been the case. For example, in late 2006 while preoccupied with funding the PDP's 2007 auto‑succession campaign, the ò̩‑at‑the‑top General Káńkpé experienced a fit of pique at the second executive director of the National Institute for Nigerian Languages, who had failed to parse the plain meaning of the expression o̩mo̩lúwàbí percentage, so the general "ordered its scrap and stoppage of its budgetary allocations" (Wakili 2012, cf. Aziza 2011 and emails of A.A. and O.E., 19 January and 3 September 2007; note that the euphemism for ministerial kickbacks (sc. kickfronts) continues to evolve, e.g. "Chúkwu said because he was not carried along, he would not release the money under his ministry" (Oyèbádé & Gyamfi 2014, emphasis added).

[Update 6 April 2017] Stray signs from 2015 suggest that generalissimo O̩básanjó̩'s 2006 revenge gambit to dash NINLAN to Ǹsú̩ká eventually collapsed — an outcome that did not need a díbi̩à áfá to foretell, given the condition of the 200 km. of federal roads separating Wáàwa Land from Ńgh̩wà Land in the Oriental Province of 9ja! Apparently in the less longthroated (post-PDP) era, Prof. Elugbe was recalled to resume his occupātus interruptus and resurrect the àbíkú/ògbáńje institute as "an Inter-University Centre for Nigerian Language Studies" (references below, archived here).

A project to accommodate the subdot and other Nigeriana in typewriters, letterpress and desktop publishing took shape in 1983 with support from the Federal Ministry of Education in Lagos and from Hermann Zapf (cf.  Hermann Zapf, ein Arbeitsbericht. Maximilian‑Gesellschaft Hamburg 1984, p. 82. ISBN 3921743281). Like other nationalist efforts, PanNigerian vanished into "the chaotic complex" when the appropriation vortex shifted to Babangidan Abuja (cf. O. Láwúyì, "Understanding the Nigerian state; popular culture and the struggle for meaning", The Transformation of Nigeria; essays in Honour of 'Tóyìn Fálọ́lá, edited by A. Oyèbádé, 511‑30. Africa World Press, Trenton New Jersey, ISBN 0865439982). Current hopes rest on civil society efforts like Lagos Analysis Corporation Technologies and African Languages Technology Initiative (Ìbàdàn).
[NOTE: Technically savvier discussion of these points, plus more doctrinal pushback from Unicode defenders, appeared on Language Log shortly after my own hapless collision with the planet's typographic authorities. See also this forthright critique, cited as an undated update by Language Log. Maybe we need to update Max Weinreich's immortal wisecrack about glossopolitics to something like "A language is a dialect with precomposed/precomposite diacritics."]
Thanks to the clout of Vietnamese and romanized Indic languages in corporate software's higher echelons, an integrated (precomposed), therefore correctly aligned and (we can hope) unambiguously searchable subdot has been made available for upper and lower roman vowels and s. This resource accidentally represents real progress for any users of 9ja orthographies who choose not to mark tone, or even for those who are prepared to play the lottery of combining tonemark alignment. Here are the Unicode and HTML (remove wordspaces) bit addresses for the subdotted letters most commonly used in 9ja orthographies, and for the nonintegrated but nonspacing (i.e. possibly "combining") acute and grave accents as well as the less important macron, plus a more fully descriptive link for each:
U + 1 E A 1 = & # 7 8 4 1 ; = LATIN SMALL LETTER A WITH DOT BELOW
U + 1 E B 9 = & # 7 8 6 5 ; = LATIN SMALL LETTER E WITH DOT BELOW
U + 1 E E 5 = & # 7 9 0 9 ; = LATIN SMALL LETTER U WITH DOT BELOW
U + 1 E 6 3 = & # 7 7 7 9 ; = LATIN SMALL LETTER S WITH DOT BELOW
U + 1 E 6 2 = & # 7 7 7 8 ; = LATIN CAPITAL LETTER S WITH DOT BELOW
U + 0 3 0 1 = & # 7 6 9 ; = COMBINING ACUTE ACCENT
U + 0 3 0 0 = & # 7 6 8 ; = COMBINING GRAVE ACCENT
U + 0 3 0 4 = & # 7 7 2 ; = COMBINING MACRON
Unfortunately the "combining" superscript accents are just as blunt an instrument as the "combining" subdot, so it would still be more reasonable for the wise bosses of Unicode to kindly provide precomposed subdots for all of the five roman vowels upper and lower case EVEN WHEN THESE VOWELS ALSO BEAR PRECOMPOSED ACUTE AND GRAVE ACCENTS. But until that glory day arrives, southern 9ja literates will be forced to choose their poison: either to tweak the alignment of the combining subdot, or that of the acute and grave accents. At least, thank goddisses, there's no need to drink both poisons at the same time; instead, the prudent 9ja typist will ensure that either the subdot or the accent is used in the composed or integrated (not the "combining") form. A fortiori, the "combining" superscript accents should emphatically not be used with plain (non‑subdotted) vowels or tonebearing nasals for which composed/integrated tonemarks exist (see complete list below). Some text editors are programmed to automatically substitute the respective composed/integrated character for the sequence of letter plus combining diacritic, but it would be naive to trust this to happen on any given day. Apple's tablet‑like OS10.8 (enervatingly named after yet another cat species — can Civettictis civetta be next?) is the worst of both worlds: all the illegibility of combining characters, wrapped in a pseudo‑composed display format so that diacritics can't be tweaked.
U + 0 0 E 1 = & # 2 2 5 ; = LATIN SMALL LETTER A WITH ACUTE
U + 0 0 E 0 = & # 2 2 4 ; = LATIN SMALL LETTER A WITH GRAVE

U + 0 1 F 8 = & # 5 0 4 ; = LATIN CAPITAL LETTER N WITH GRAVE
By whatever means tones manage to be typed, the tonemarks given here for any of the Benue‑Kwa (BK) languages follow a dual convention, consistent with best practice known to me although not necessarily matching current popular or official usage — fully explicit tonemarking being rare outside of Yorùbá. Throughout BK, [ ́ ] = high, [ ̀ ] = low, but marking differs in a principled way between the BK1 and BK2 subgroups correlated to prosodic type as discussed in Manfredi (2009a). For clarity, the pitch labels H, M, L and ! (downstep juncture) are added parenthetically. In BK2 (comprising the Gbè, Yorùbá, Nupe and Ìdọmà macro‑clusters) with 3 lexical tones, marking economy is paradigmatic i.e. syllable‑by‑syllable, thus no mark = mid, but in BK1 (the historic remnant including Àkan, Ẹ̀dó, Ìgbo, Tiv, "Bantu" &c.) with only 2 lexical tones, marking economy is syntagmatic, thus no mark = same as preceding and a sequence of two high marks = downstep starting on the second (Welmers & Welmers 1968, cf. Christaller 1875, Nwáchukwu 1995), e.g. Ẹ̀dó Ólokún (HH!H) '[tutelary supernatural, from Yorùbá]'. Furthermore, following Bám̄gbóṣé (1966) and Ámayo (1976), downstep preceding nonhigh is marked by a word‑internal period, e.g. Yorùbá Oló.kun (MH!M) 'possessor/epitomē/personfication of òkun (LM) [the ocean]' vs. Olókun (MHM) 'possessor/epitomē/personfication of okun (MM) [energy]' and the same expedient conveniently generalizes to a non‑spreading juncture between high and a following low, e.g. Yorùbá oló. (MH!L) 'possessor/epitomē/personfication of an òdù (LL) [clay cauldron]' vs. olódù (MHL) 'possessor/epitomē/personfication of an odù (ML) [8‑bit oracle sign]', cf. also Ẹ̀dó .̩ (H!L) 'yesterday'.

JolanPanNigerian, the 20 year old PostScript face created in order to accommodate Nigerian orthographies (see p. 396 for details), looks grizzly on the screen but prints out smoother. (Not only people get grizzled with age — a consoling thought!)

As to content, an apologia is called for. Much of the document de travail has been superceded in recent years, especially due to two steps which I took in response to the intractable mysteries faced by more standard kinds of analysis: (i) a shift from the autosegmental‑metrical hybridity of Chapter 1, to toneme‑free metrics (also here); and (ii) a move from the projected lexical conceptual structures of Chapter 2, to compositional lexical syntax (also here and here). In the interim I've also (iii) backed off of the strong WYSIWYG morphology conjecture of Chapter 3, to settle for an indispensable minimum of overt structural cueing, consistent with parametric, derivational phases (here) and irreducible to Distributed Morphology — a style of hyper‑ or meta‑phonology cum recapitulation of syntactic "debris" (Halle & Calabrese p.c.). All these changes were prefigured in the 1991 text, but not so for (iv) "scopophobia", a principle of syntax‑semantics mapping — Chapter 3 scrupulously avoided QR but offered nothing in its place apart from appeals to intelligent pragmatics. My current interest is (v) to combine the foregoing claims in order to treat focus phenomena without cartographic/criterial feature checking (here and here), and in order to capture subject/object and argument/adjunct asymmetry in wh‑dependencies.

My best luck came at the start of the journey, to compare Ìgbo and Yorùbá while learning about each from eminent southern Nigerian scholars and traditional verbal artists. That happenstance was somehow inevitable for an alárìnso̩ (the efficient translation into Yorùbá, applied to me by my ASUU sister Dr. Yétúndé Olúwafisàn, of the concept of 'peripatetic linguist with theatrical and mendicant airs') working in the then‑thriving federal university system at a time of cheap and safe public transportation. Under such conditions, the comparative window opened wide enough to show one nontrivial difference in the relation between sound and meaning. The agenda of topics could have been shorter, though my committee kindly refrained from pointing out this fact. My revered colleague Dr. Frannie Oyèbádé gave me friendly grief about the book's polymathic title, but from my outsider's standpoint I can't imagine engaging with these languages to the needed extent without facing what Chomsky calls Orwell's Problem. Maybe a grammarian can untangle puzzles of ideology and demography in the cognitive science vein (cf. Wallerstein quoted here).

My worst typo is the omission of Kay Williamson's name from the Acknowledgements (p. 13), although her generous mentorship is writ throughout. She was too polite to mention my mistake; when a third party pointed it out in 1994, she gracefully accepted that no vendetta was behind the lapse.

Tone correction: LHL tones printed on the language name "Igala" on pp. 24 (fn. 15) and 31, due to Banfield (1914, 178) and Armstrong (1965, 78), are probably an anglicism. Ìlò̩rí (2009) gives the name with MHL, but that's a likely Yorùbáism, because two independent citations by speakers give initial H while mentioning the restriction that "[t]here is no noun in Ígálâ that begins with the mid tone" (Ètù & Mìáchî 1991, 7, cf. Ọmachonu 2012, 22). Loanword change HHL>MHL in Ìlò̩rí's Yorùbáphonic citation is likely, given that Yorùbá prohibits H on initial onsetless syllables (Ward 1952, 37). Tonal anglicization is common in proper names all over West Africa, e.g.

"Í ì g b o" HLL for Ìgbo LL [= colonial "Ibo"]

"Ọ̀ n ị́ ị̀ c h a" LHLL for Ọ̀nịcha LLL [= colonial "Onitsha"]

"À k á n" LH for Àkan LL

and so on. (The third of these caught me napping in this paper.) One more "Igala" confusion in public record: WorldCat's entry for Ètù & Mìáchî's school text mistypes the medial vowel of the language name as [i], but in fact the authors write it consistently as [a].

The limits of downstep in Ágbò̩ sentence prosody
IRCS Report 92‑37, edited by M. Liberman & C. Maclemore, 103‑15. Institute for Research in Cognitive Science, University of Pennsylvania, Philadelphia.

The complete list of 81 examples transcribed in the Appendix (pp. 110‑12) can be heard in the same order here. Here's a foto of the speaker, Julius Ògbú, and me.

Significant correction: Ex. (18a) as cited on p. 109 is observationally correct in some prominent Ìgbo varieties — e.g. it occurs as such in Ḿbàisén and adjacent areas — but not in Standard Ìgbo, moreover the form as given on p. 109 is seriously misleading with respect to considerations of clause‑typing. In Standard Ìgbo, the verb root plus suffix in a subject question of this inflectional type bears L, and not downstepped H:

Ònyé hù̩‑ru̩ Ézè? 'Who saw Ézè?' = [LH LL HL].

But Standard Ìgbo does maintain the downstepped H in subject relative clauses like (18a) = [H!H !HH H!H]. Accordingly, one might well claim that T‑to‑C (or Infl‑to‑C) does occur in (18a), just as indicated in the paper, but there is no prosodic evidence for parallel treatment of (18b), contra the little upward arrow to the left of ‑rV in the tree structure in (18b). Incidentally, the identification of Ìgbo finite ‑rV as a morphological instantiation of the Infl or Tense node of the clausal Middle Field, assumed in 1992 the paper, must be abandoned for independent reasons of temporal and aspectual quantification. Specifically, the longstanding controversy in the Ìgbo literature regarding the temporal content of ‑rV inflection dissolves, once ‑rV is recognized to have the distribution of an argument‑type clitic.

Otherwise, the general point of the paper remains unaffected: so‑called "upstep" is epiphenomenal, and is not an upside‑down counterpart of "downstep" as pretended in taxonomic ("tagmemic") work by E. Pike and maintained by many Africanists with the help of enriched autosegmental‑metrical notation. Rather, "upstep" is no more than the phonetic realization of antidownstep (downstep reset), a phenomenon itself constrained by syntactic phrasing. Several elementary and general observations support this conclusion, quite apart from the particular analysis of Ágbò̩ presented in my paper. First, there is no antidownstep without a preceding downstep in the relevant prosodic domain. Secondly — and this point was admitted anecdotally during the roundtable discussion at the 1992 UPenn workshop by the two invited SIL Mayanists — Mayan languages do not show upstep cumulation, contra E. Pike's published descriptions that started the whole upstep goosechase. Naturally, upstep retains support as a strictly phonetic category, my only purpose here being to show that it plays no role in the statement of linguistically significant generalizations. In sum, phonological use of the term upstep is, on current knowledge, nothing more than a hypostasis or in other words a mystification. SIL/Wycliffe may possess excellent soteriological reasons to look "upward" as much as "downward", but natural languages including Ìgbo and apparently also the Mayan family are quite innocent of this skyward temptation, and should not be blamed for it.

[Update 6 December 2012] Another telling indication that syntax is not 'different' (in the sense of Bromberger & Halle 1989) is that not only prosodic footing, but also syntactic agreement, has now been enthusiastically offered as grist for an upward‑looking parameter of structural variation across natural languages (Baker 2008). Automatic sacrifice of restrictiveness is always expedient in the short term, but always too a bad idea for constructing testable theory‑space (Martin & Osherson 1998) and at least as far as Niger‑Congo languages are concerned, always a recipe for exoticism.

Significant empirical wrinkle: contra the standard description exemplified in ex. (5b) on p. 92, Adéṣọlá (2005, 190f.) observes two examples of ōrātio oblīqua in which the possible reference of an embedded 3sg. nominative clitic can include the main clause subject. Specifically, ó may optionally share the referent of Olú in the following examples:

(i)   Olú ti       gbà      [kí          ó      má    .jẹ  ìrẹṣì mọ́].
  O.   AUX receive COMP 3SG AUX eat rice   any.more
  'Olú agreed that s/he (= Olú or someone else) should not eat rice again thereafter'

(ii)   Olú ti       kéde                      [pé         ó       ń       bọ̀      l'ọ́la].
   O.   AUX cry.proclamation COMP 3SG AUX come tomorrow
   'Olú announced that s/he (= Olú or someone else) is coming tomorrow'

Granting that these data entail a breakdown of referential complementarity between the independent (òun) and clitic (ó) 3sg pronominal expressions, such breakdown is not unusual for morphological competition among pronominals across the binding literature as a whole (as reviewed here). The more relevant question is whether Adéṣọlá's observations disprove domain extension and by implication any syntactic account of antilogophoricity, motivating instead an a‑syntactic mechanism for logophoric effects, such as a de se dreamtime operator (Anand 2006, cf. Lakoff 1970).
Note that the dreamtime account doesn't come free of charge: it must pay the incalculable price of insulating semantic interpretation from syntax in principle, via the general possibility of "overwriting semantic parameters" (Anand 2006, 64, cf. Chierchia 1998), besides incurring the more limited tax of treating as strictly accidental the uncontested absence of phenomena like (i) and (ii) in cognate languages where "logophoricity" has been studied, such as Gbè (BK2), Ìgbo and Abe (BK1).
Before jumping to unfalsifiable conclusions demanding unlimited bailouts from the Semantical Central Bank, it's worthwhile to check the more economical possibility, that some independent syntactic factor explains the nominative clitic's lack of antilogophoric behavior in Adéṣọlá's data. Pending systematic investigation, it jumps out from both examples that the indirect discourse containing the anomalously interpreted nominative clitic is presumptively not a syntactic complement, but rather a paratactic adjunct. If so, then domain extension (antilogophoricity) would not be expected to occur, so the data don't falsify the null, syntactic theory pace Anand.
To a casual observer, English translation may conceal what is generally accepted in Yorùbá literature, namely (i) that the surface L tone of gbà 'receive' diagnoses surface intransitivity and marks the subsequent clause as an adverbial adjunct (Déchaine 2001, cf. Rosenbaum 1965), and (ii) that the predicate kéde 'announce' decomposes transparently as an unergative expression with immediate constituents 'cry' plus òde 'proclamation' (Abraham 1958, 361), similarly entailing that an immediately following clause necessarily occupies a noncomplement position. Parallel considerations of philological adequacy refuse Schlencker's philosophical "plea for monsters" (2003). In general, logophoric construal may reflect a structurally loose condition on information flow in discourse (Safir 2004), but antilogophoric effects apparently reflect narrow c‑command. This noncomplementarity is obscured by the functionalist notion of "logophoric pronoun".

"Corrected republication" of subeditor's typographic botch in same journal vol. 29 pp. 95‑121.
Update: Holloway & Vass align the stereotype of the "Bantu" as a "homogeneous group" sharing a "common origin" (1993, xiv) with the latter half of a famous political dyad, "the house Negro and the field Negro back during slavery" (Malcolm X 1963, 10). They state as follows:
"In North America, Wolofs were primarily employed as house servants. …But as field workers the Bantus were kept away from the developing mainstream of white American culture." (1993, xx, xxv)
Their view however contrasts with a Caribbean
"discourse that has become widespread… wherein the 'Bantus' or 'Kongos' of central Africa stand for mixture, while the coastal Yorùbá and Dahomeyans (often referred to as Guinea or Nago) stand for purity and authentic Africanness" (Johnson 2007, 213).
Taking these indirect reports at face value, the question is then why, in the respective zones of plantation settler-economy, the "Bantu" demographic profile acquired opposite polarities on the scale of perceived cultural assimilation.

Significant correction: On p. 104, the gloss given for Yorùbá the left‑hand example in (53a) i.e. without the pluralizer àwọn should not include the definite plural 'the dogs'. The excluded reading is in fact available in a similar example of Mandarin, as reported on p. 29 of R. Yang [2001] Common nouns, classifiers & quantification in Chinese (Dissertation, Rutgers University, New Jersey), but the two examples are nonparallel: the Mandarin crucially lacks a sortal classifier which arguably corresponds to little n, and in the Yorùbá example the notional noun has a closed‑class prefix which again arguably corresponds to little n. The interpretive difference disproves any structural equation between the bare noun root of Chinese and the minimal free form of Yorùbá; the latter is structurally a bare singular as discussed below, and allows a plural reading if either indefinite or inanimate, as preciently noticed by Welmers [1973] African Language Structures (University of California Press, Berlekey), p. 220.
Ìgbo initiation; phallus vs. umbilicus
Cahiers d'études africaines 145, 157‑211. [ISSN 0008‑0055]
This article fills in a placeholder blurb in my dissertation (§4.5, pp. 304f.). The pertinent É̩hu̩gbò text, reproduced on pp. 195‑201, was copied verbatim from the dissertation (pp. 343‑48) where it was transcribed with more attention to content than to dialect‑particular inflectional morphology or to consistency of orthographic word division — both issues in need of reconsideration. The respective audio (runtime 7:31), posted here, was recorded on 19 June 1977 from Éléje Aghá, a renowned díbì̩a 'oraclist' of the Ńdi̩ Uchè Ú̩̩ moiety of Kpóghirikpó village, while seated in the veranda of Ńnàlí̩ Ì̩du̩ma whose supporting voice can be heard in the background.

Significant correction: On pp. 177f., I proposed in passing that the Ìgbo nouns for 'reincarnating spirit double' and 'day(light)', both of which are pronounced chí, share a common root which is still productive in the language as a so‑called 'verb extension' meaning either 'repeat' or 'return'. This idea is however disproved by one simple fact which I should have checked at the time, namely that the predicative root in question has an aspirated onset consonant in all Ìgbo dialects which include this phonological feature, whereas the two nouns do not (cf. pp. 110 and 119 of Rev. Ígwè's 1999 Ìgbo‑English Dictionary). Hence it is impossible for that predicative root to be historically connected to either of the two nouns, and so an alternative explanation is required if the nouns are etymologically linked to each other at all. (Of course the null hypothesis is also possible, that 'day(light)' and 'reincarnating spirit double' are accidental homophones in Ìgbo, but as astute a cultural commentator as Òdógwu Chínù̩á Àchebé ventures otherwise, in his famous 1975 essay "Chí in Ìgbo cosmology".) Moreover there can be no doubt that the 'day(light)' meaning of chí is ancient, indeed it is reconstructed by Mukarovsky (1976, 146, 152) all the way back to a stage close to the ancestor of the entire Niger‑Congo language family, therefore it would be highly unlikely for an etymology of this word to be still recoverable Ìgbo‑internally. Accordingly, a new proposal is made in the final section of this manuscript, taking into account a cosmological comment in Melzian's È̩dó dictionary for the analogous noun è̩hi: "It is believed to be 'with a man all the day' " (1937, 51). Based on this remark (which is probably attributable to Melzian's primary consultant, Mr. H.G. Amadasu), and on supporting evidence cited there, I suggest that the Ìgbo noun for 'reincarnating spirit double' is historically identical to the noun for 'day(light)' thanks to a trivial metonymy of a thing to its canonical context, motivated by an assumption which was originally made by Northcote Thomas (1914, 19) and which can scarcely be doubted by anyone who has compared the two neighboring civilizations, to the effect that the cosmological pragmatics of È̩è̩hi and Ìgbo chí are remarkably parallel. The analogy is further demonstrated at Ágbò̩ ("Agbor"), the intermediate border kingdom with strongly bicultural Ìgbo and È̩dó leanings, where è̩hi appears in countless personal names in the same 'slot' in which chí is found in the eastern Ìgbo counterparts, to all appearances synonymously, e.g. È̩hi edú = Chí nà‑edú 'the reincarnating spirit‑double leads'.
UPDATE 23 April 2014: The standard assumption that twins infanticide had economic utility, reducing investment in offspring of lower life expectancy, still begs a cultural explanation for a widespread but far from universal precolonial practice. Ethnographers may paraphrase local opinion about "uncanny" (Thomas 1913, 12) or "unnatural" births: "For a woman to bear more than one child at a time was regarded as degrading humanity to the level of beasts" (Úchèńdù̩ 1965, 58; cf. Basden 1921, 57f, Thompson 1971, 10, 79), but vague sentiments of aversion, potentially reflecting "secondary reasoning and reinterpretations" (Boas 1910, 67), fail to address intricately stratified legal‑cosmological codes like the 100‑plus ǹsó̩ àla 'communal taboos' (lit. 'things prohibited by the earth'), including birth omens, operant at Ǹri well into the 20th century (Ó̩nwu̩ejìó̩gwù̩ 1981, 52ff.). Schapera dismissed the "obvious explanation" of generic abnormality as circular, seeking instead "the meaning of the various customs related to twins" in indigenous ideas such as the "occurrence of two individuals with identical personalities" (1927, 134ff.), but despite this advice the most influential 'theory' of the matter merely rephrased the commonsensical account in elevated terms like "paradox", "anomaly", "dilemma" and "structural contradiction" (Turner 1969). In two adjacent northwest Cameroun communities speaking Benue‑Kwa (socalled wide Bantu) languages, terms rendered in English as "single twin" are ritually applied to biologically singleton births by oraclists seeking to interpret "individual and social problems in [terms of] the behavior of discontented ancestors" (Diduk 1993, 552, cf. Argenti 2011, 283, 286). Extending the idea to Ìgbo, hypothetically the chí could have been regarded as the individual's twin, and conversely one member of a biological twin birth — but which one?—was therefore the other one's chí. If so, then a twin birth could not lead to further reincarnation. This conjecture awaits relevant evidence pro or con.

Tone correction: LHL tones printed on the language name "Igala" on pp. 24 (fn. 15) and 31, due to Banfield (1914, 178) and Armstrong (1965, 78), are probably an anglicism. Ìlò̩rí (2009) gives the name with MHL, but that's a likely Yorùbáism, because two independent citations by speakers give initial H while mentioning the restriction that "[t]here is no noun in Ígálâ that begins with the mid tone" (Ètù & Mìáchî 1991, 7, cf. Ọmachonu 2012, 22). Loanword change HHL>MHL in Ìlò̩rí's Yorùbáphonic citation is likely, given that Yorùbá prohibits H on initial onsetless syllables (Ward 1952, 37). Tonal anglicization is common in proper names all over West Africa, e.g.

"Í ì g b o" HLL for Ìgbo LL [= colonial "Ibo"]

"Ọ̀ n ị́ ị̀ c h a" LHLL for Ọ̀nịcha LLL [= colonial "Onitsha"]

"À k á n" LH for Àkan LL

and so on. (The third of these caught me napping in this paper.) One more "Igala" confusion in public record: WorldCat's entry for Ètù & Mìáchî's school text mistypes the medial vowel of the language name as [i], but in fact the authors write it consistently as [a].

Tone typo: The second word in fn. 27 (p. 270) should be Ékpè [HL] and not Èkpe [LL]; the LL item refers to a dance genre (i.e. a subtype of the large category of performances called in Ìgbo égwu [HH]) rather than to the title society under discussion which happens to deploy its own proprietary masked dance representations. The latter institution is denoted by the HL item wherever it is found, including the southern and eastern Ìgbo‑speaking area (cf. Ígwè, Ìgbo‑English Dictionary, University Press Ltd., Ìbàdàn 1985‑1999, p. 155) and specifically in Árụ̀ (= colonial "Arochukwu", cf. video interview with Ézè Árụ̀ by I. Miller, 2008) where the title society has big political clout. Two observations show that the respective forms with HL and LL represent one single word which traveled distinct historical paths, as opposed to being random near‑homophones. First, festival songs of "Èkpe" [LL] in Ọ́màáhyá (= colonial "Ụmụahi̩a") include numerous emblematic references to ágụ́ [H!H] 'leopard' (cf. E. Íkeokwú long essay, Department of Linguistics & Nigerian Languages, University of Nigeria, Ǹsụ́ka 1984, pp. 18f.). Second, the Ẹ̀dó word for 'leopard' is è̩kpe̩n (cf. Melzian, Concise Dictionary of the Bìní Language of Southern Nigeria, London, 1937, p. 53), with the same LL as in the Ìgbo word for the dance genre. (The nasalization of the root in the Ẹ̀dó reflex is probably related to the syllabic nasal which constitutes the noun prefix, sometimes singular and sometimes plural, of 'leopard/panthère' in many of the languages sampled in the Benue‑Congo Comparative Wordlist, Ìbàdàn 1968, pp. 222‑25.) In sum, the existence of the form ékpè [HL] in Ìgbo‑speaking communities reflects the borrowing from Èfịk of the historic word for 'leopard' along with its Èfịk pitch pattern of [HL], used as the proper name for the leopard‑themed title society which flourished in the catchment area of the Èfịk trade empire known to European merchants and colonists as "Old Calabar" (cf. Talbot, Peoples of Southern Nigeria, 1926, pp. 183f.). This borrowing endowed many southern and eastern Ìgbo‑speaking communities with a secondary lexical item separate from the primary/inherited Ìgbo form of the word with LL, which had meanwhile lost in Ìgbo the literal denotation of 'leopard' (having been supplanted by the hypokoristic ágú̩, literally 'the ravenous one', cf. águ̩ú̩ or águ̩ó̩ [HH!H] 'hunger') and become semantically opaque in the specialized context of phrases like í̩gbá èkpe [H!H LL] referring to heroically vigorous dance‑play — so‑called from its emulation of what the 1986 Nobel laureate in literature might like to call the leopard's "tigritude" or more prosaically, "a type of dance requiring much energetic action and so restricted to able‑bodied young men" (Ígwè p. 155).

Significant empirical wrinkle: The cartographic errorism — what would today be called unavoidable and regrettable targeting error — responsible for sticking the name "Calabar" on the Efịk capital is much less complex in legendary inspiration, and slightly less farfetched in geographic distance, than modern historians have supposed. As quoted in the paper (p. 254), Jones wondered whether "the European attribution of the name Old Calabar to the Efịk people could be a reflection of the Korome myth of origin [… about] the place which the Opukoroye line of Kalaḅarị kings claimed as their original home" (1965, 159). More plausibly and prosaically, Ejituwu suggests that the intended referent of the "old" term in this myth was not the Efịk‑speaking village group on the "Rio da Cruz", but instead a Kalaḅarị‑speaking settlement (subsequently abandoned) on a branch of the "Rio Real" estuary labeled "Old Calabar River" by Barbot's 1699 "New Correct Mapp of Calbar River" (reprinted by Barbot 1732, 462 and Ejituwu 1998, 137). Further ambiguity (as if any were required) is supplied by the fact that "when New Calabar itself segmented from 1879 to 1885 […] [t]he Kalaḅarị in Bakana, Abonema and Buguma continued to regard New Calabar as Elem Kalaḅarị, which means 'Old Calabar', and the latter continued to appear in official documents till 1931" (Ejituwu 1998, 142). None of this confusion is surprising, given that adnominal modifiers like old and new are indexical "shifters" whereas map terms ideally aren't. But unlike Jones' frankly speculative account of the Efịk mistaken identity for "Calabar", Ejituwu's explanation of the mishap has independent documentary support and is moreover simpler: no need to assume that Dutch mappers of 9ja's eastern coast had even indirect access to Kalaḅarị dynastic tales, if what happened is that they ploddingly reproduced some coastal traders' casual misplacement of the older of the "Old" Calabars — i.e. the one so designated by locals in the 17th century — by a few hundred miles, to a different slaving depot a few estuaries further along to the east, albeit in a very different linguistic territory.

ABSTRACT: Niger‑Congo's Kwa and Benue‑Congo zones, jointly covering most of tropical Africa, run between isolating and agglutinative types. Historical phonology finds few shared innovations above the local cluster, but assuming the phase theory of generative syntax, a sharp division emerges based on the timing (early/VP vs. late/TP) of PF‑spellout.

UPDATE 18 July 2007: A letter in the current issue of Nature reports that paleontological and genetic data converge in reconstructing human origins to an area which — as I can't help noticing — happens to coincide closely with the current Benue‑Kwa speaking area. See this screenshot of Fig. 2. Likely origin of anatomically modern humans from p. 347 of A. Manica & al., "The effect of ancient population bottlenecks on human phenotypic variation" (Nature 448, 346‑48, 19 July 2007). Of course the observation is anachronistic, because the physiological reference point is >50K years old while BK's collective identity is presumably much younger, but the areal coincidence is still striking. A more neutral paraphrase: present BK‑speaking populations include the greatest phenotypic as well as genetic diversity of any large‑scale human aggregate. This result cannot lessen the general interest of comparative BK studies, but I predict that someone soon will conveniently forget the "K" (Kwa) part of "BK" (Benue‑Kwa) and try to interpret these maps in a Bantuist vein!

UPDATE 15 April 2011: It's disappointing that anyone would be counting "phonemes" nearly a century after Jakobson, Karcevsky & Trubetskoy discovered binary distinctive features and implicational universals (la regularité des rapports de corrélations), cf. "Quelles sont les méthodes les mieux appropriées à un exposé complet et pratique de la grammaire d'une langue quelconque?" (Actes du premier congrès international de linguistes à La Haye, du 10‑15 Avril 1928, 32‑36; reprinted in Roman Jakobson Selected Writings 1; Phonological Studies, 3‑6. Mouton, The Hague) and 25 years after Kaye, Lowenstamm & Vergnaud refined this idea as a sub‑syntax of unary/privative phonological elements, cf. "The internal structure of phonological elements; a theory of charm and government" (Phonology Yearbook 2 [1985], 305‑28). Nevertheless it's still probably significant that the demography of taxonomic (pre‑Jakobsonian) lexical contrast units — roughly, phonetic phenotypes — converges on the same originating population as does the demography of human anatomical genotypes: once again, the presently‑existing historically‑defined linguistic unit most closely corresponding to the set of languages in question is Benue‑Kwa. Twice lucky? See the top half of " Fig. 2. Likely area of language origin" from p. 347 of Q. Atkinson, "Phonemic diversity supports a serial founder effect model of language expansion from Africa" (Science 332, 346‑49, 15 April 2011) or this screenshot.

UPDATE 15 September 2012: Some of the same issues are covered in Hyman (2004), a learned survey enlarging Westermann's (1927) broad observation of east‑to‑west decline in morphosyntactic complexity and in the maximum size of predicate roots. In the absence of theory, of course, there can be no expectation of quantal restructuring. Instead, Hyman suggests (i) that the innovations under investigation "modified the proto system… in an areal fashion" (p. 71) and (ii) that the process was not unidirectional, since Ìgbo is cited as a language in which "doubtless… extensions have arisen via renewals" (p. 86). But how far can a theoretically untrammelled picture of reversible Wellen be maintained while still admitting a large‑scale structural shift towards isolating syntax and monosyllabic roots? Can such a dramatic diachronic asymmetry, expressed across vast stretches of time and space, be more than a statistical fluke? Part of the problem may be that Hyman bravely assigns himself the whole of "Niger‑Congo" (the world's oldest and most complex language family) as the canvas for his illustrations, whereas Westermann's original observations were restricted to the more tractable — but still impressively big — zone which came to be known as "Benue‑Kwa" (e.g. Elugbe & Williamson 1977). It's also surprising that someone who went on to write Hyman (2011) would not follow up his own observation that "almost all Bantu languages show stembound phonological prosodies" (p. 85) by mentioning the markedly richer tonemic inventories at the "Kwa" end of the spectrum. (Either that's another accident, or else tone is really "different" after all. Not both.) Aligning his three parameters of change, Hyman notes that "at least relics of the original morphology survive beyond the syntactic and phonological restructurings" (p. 86), entailing that "syntax" changed autonomously to some extent, and hinting at no mechanism connecting syntax to the shape of roots. Coincidence upon coincidence.

UPDATE 16 May 2013: BK2's birth being the hypothetical result of deletion (specifically, the erosion of finite inflection), or so I say, risks the irrelevance of a linear branching model of substantial inheritance — as opposed to disinheritance. It makes you wonder what share of i‑language speciations are of this general type, and whether identification of more such events could reduce apparent radiation/multibranching in archaic Stammbäume — a matter which continues to disquiet Indoeuropeanists, most of whom understandably were trained to study e‑language (e.g. Garrett 1999). Genetic reduction is a live topic in cellular phylogeny (Bapteste & Gribaldo 2003) though not as hot as incongruence/lateral transfer (Leigh & al. 2011).

"A recurrence of structures" in collapsing Nigeria
Radical Egalitarianism; local realities, global relations [publisher page], edited by F. Aulino & al., 119‑36 with consolidated volume endnotes and references (Fordham University Press, Bronx, New York, 2013, ISBN 0823241904).

[cover page plus 17pp. prefinal proofs of main text plus 4pp. A4 of individual endnotes and references, last modified 18 February 2012.]
ABSTRACT: If the Southeast Asian "galactic polity" is defined by centripetal‑centrifugal "pulsation between modalities" of power (Tambiah 1976), something similar is true of West Africa's 'Asiatic' social formations — indigenous tributary monopolies that flourished during the transatlantic slave trade before becoming "encapsulated" in British rule (Otite 1975). Structural ambivalence explains how Fortes & Evans‑Pritchard (1940) could lump "stateless" Ìgbo and nomadic Nuer together into the "acephalous" political type. This paper reviews three southern Nigerian examples of evanescent hierarchy. In April 1979, Íkenchúku the youthful ruler of Ágbọ̀ Kingdom died from nocturnal gunfire during a land case and an electoral campaign, as an elderly chief was rewriting Ágbọ̀ history to push back the pendulum from absolutist primogeniture towards collective lineage rights. In November 1995, the writer Ken Saro‑Wiwa was eliminated by "judicial murder" ostensibly because he had denounced a list of ten Ogoni chiefs — four of whom were subsequently lynched — as having sold out to Shell Oil Corporation and General Abacha. In November 2000, an Ìgbo anthropologist was roughly rebuked by an Ìgbo historian for refusing to parse the slogan Ìgbo énwé ezè 'Ìgbo has no paramount ruler' as synonymous to colonial cliches like "Biafran society is traditionally egalitarian" (Òjúkwu 1969 cf. Meek 1937). Instead of treating these perturbations as unrelated events, Tambiah's framework suggests they are causally linked in a long‑term social formation, within which the entrenchment of local political brokerage is complemented by the steady collapse of nationalism.
BIBLIOGRAPHIC NOTE: The main descriptive source of this study is Chief Augustin È̩gwabó̩ Ìdúùwe̩'s History of Greater Ágbò̩[r]. That irreplaceable text remains unpublished today, three decades after the author entrusted the manuscript to me, so I belatedly and apologetically post it here in its unfinished form of circa 1982. An unattributed ten‑page paraphrase/extract of Ìdúùwe̩'s manuscript is included in J. Butcher & al. "A critical analysis of the royal chronicle of Ágbọ̀r" (Benue Valley Project Paper 13, Dept. of History, Dalhousie University 1975). According to the introductory comment by Professor J. Webster, the material was forwarded by an unnamed history graduate of Ìbàdàn University.
Correction: as now debunked, the "Possible image of a salon in General Babangida's château" presented in an earlier draft of this paper as §5.6 actually shows a California mansion. Nevertheless Babangida's immense personal wealth has no legal explanation.
UPDATE1: The issues reviewed in this paper receive a less political take in a 25‑minute TV documentary, "George Oṣòdì: Kings of Nigeria", eliciting my response: "Déin in Abachan drag?".
UPDATE2: In northern 9ja, the British rāj ended Sokoto vassalage in 1902-03 (Smith 1960, 201), but Lugardian indirect rule breaks down in a context of democratic opposition, thus in June 2014 the APC state governor blocked the Abuja PDP from imposing a client, filial successor to the Kano emirate.

For some of these essays, the relevant tube of the pipeline can be regarded as clogged, and the items in question merely blogged. To steal a metaphor from my teacher Jochem Schindler, "modern linguistic publications have a very short half‑life" — the time it takes for "half of their claims to be proven wrong". If things are so bad for printed books and articles, then for these mere electrons it's a race against exponential decay before any scientific weight converges to the infinitesimal.

The etymology of ogan (ogã) proves the Gùn‑gbè origin of Candomblé Jeje
[3 pp. A4, last modified 13 October 2013]
ABSTRACT: Yorùbá ò̩ 'boss' (< ‑ 'stand aloof') is not cognate to Fọ̀n‑Gbè gán 'chief, patron' (< ‑gán 'support'), pace Herskovits (1956, 156). By standard criteria of form and meaning, the closest Westafrican correspondent of the Afrobrazilian ritual title ogan (Carneiro 1940, 274, cf. Landes 1947) is Gùn‑Gbè ògán, its functional counterpart in the vodun of Xọ̀gbónù alias "Porto‑Novo" (Rouget 2001, 97). This philological finding is demographically significant, because the most vodum‑oriented candomblé tendency happens to be called Jeje (also spelled Gêge), while Jeje (also spelled Djédjé) is also an exonym of the Gùn‑Gbè population (Capone 1999, 15 fn 6).

Plentiful typos aside, I also managed to reverse the meaning of the mathematical term "diagonalization", which Wagner had applied sarcastically to the mainstream literature of syntax‑free prosodic analysis. In fact the exact aim of this talk was to apply Wagner's syntactically non‑diagonalizing idea to Benue‑Kwa!
Ineffable tenses in Benue-Kwa and Romance
Research document, 12 September 2012.
[handout, 3 pp. A4]
ABSTRACT: Some natural languages can't distinguish past from present perfect without recourse to periphrasis or context. This expressive gap is unexpected if tenses are autonomous meaning postulates (Reichenbach 1947, Hornstein 1990, Giorgi & Pianesi 1997), but is grist for theories where tense interpretations emerge from syntax-pragmatics interaction indirectly (McCawley 1971, Vikner 1985, Enç 1987). English has an unambiguous present perfect (*I have danced yesterday, Klein 1992) but French doesn't (J'ai dansé hier taking over Je dansai hier), and the atrophy of the simple preterite in northern Romance coincides with several other developments related to case, agreement and aspect (Zamboni 2000, 87 cited by Ledgeway 2012, 314). In the Benue‑Kwa (BK) subgroup of Niger‑Congo, an unambiguous present perfect occurs in most of the major clusters, including Àkan, È̩dó, Ìgbo, Cross, Plateau and Bantoid, but does not exist in a substantial, contiguous subset — call it BK2 — comprising Gbè, Yorùbá, Nupe and Ìdo̩mà, where any finite affirmative episodic predicate in principle allows either present perfect or simple past construal. This bifurcation of BK arguably followed on the erosional loss of finite affixation in BK2, and introduced other correlated changes of a quantal nature in its wake (Manfredi 2005a, 2009). One reason UG doesn't need to stipulate a tense system is that time reference is partly redundant with default interpretation of lexical Aktionsart (Green & Ígwè 1963, 53; Welmers & Welmers 1968, 76; Dowty 1986, Déchaine 1991, Sorace 2000). But the crosslinguistic parallelism is incomplete: in southern Romance, present perfect morphology automatically codes for recent past, but in BK1 these two traits are orthogonal (Welmers 1973).
Tense parameters and serial verbs
[2nd draft, last modified 12 July 2005, 34 pp. A4]
Invited in 2002 to a project originally entitled Studies in the Syntax of Kwa; a generative perspective, edited by E. Aboh & J. Essegbey. Second draft, much revised in response to substantive comments from the editors, was withdrawn 9 May 2007 after the (technically anonymous) external reviewer refused to even read it on the creative excuse that it's "dense" and "flowery" — if he meant "al dente" and "floury" he may be pardoned on orthodontic and dietary grounds although he should nevertheless have been ethical enough to disqualify himself instead of shirking the job while accepting the reviewer's honorarium! Less excusable was the decision of the editors not to insist that the publisher obtain an actual review of the chapter, in the absence of which I was unfairly placed in the position of having to guess how much of the reviewer's problem was due to his delicate stylistic sensibilities and how much was an unwillingness to read substantive criticism of his own work and that of his close cumpari. (No empirical or theoretical errors were indicated in the non‑review which he provided.) Another debilitating confusion on the part of the editors was their concept of "Kwa" whose descriptive coverage doesn't coincide with any proposed historical use of this term (e.g. Greenberg 1963; Williamson 1989), conforming instead more or less to Westermann's lexico‑typological sense of those "Sudanic" languages which tend to monosyllabic roots (1927, 20). In this way the project lost its coherence as a comparative syntax handbook, and the volume which eventually appeared (chez Springer, with the title Topics in Kwa Syntax, ISBN 978‑90‑481‑3188‑4) would have been more transparently titled Syntactic studies in some of the more isolating Benue‑Kwa clusters, namely Gbè, Àkan & Yorùbá, with special reference to Gùn‑Gbè (cf. review by M. Dakubu, Studies in Language 34, 442‑52).
UPDATE: Ọmọruyi (1991) — a lucid article which has belatedly come to my attention — presents further massive evidence of the inflection of Ẹ̀dó finite predicates by prosodic morphology. It confirms and clarifies cited observations (Melzian 1942; Aikhiọnbare 1988) which were already enough to falsify the view of Stewart (1998a, 2001; cf. Baker & Stewart 1991, 199b, 2002) as to the position of Ẹ̀dó in the parametric division of Benue‑Kwa. To be clear, no one disputes that both finite inflection and serialization differ structurally across the vast and complex Benue‑Kwa group. The controversy concerns (i) what counts as finite inflection as well as serialization and (ii)  how these two nonuniform states of the human language faculty are causally related to each other. A revised version of my manuscript should integrate Ọmọruyi's generalizations about inflection, plus those of Ogie (2009) about possible serializations in the language. Both Ọmọruyi's and Ogie's studies also falsify the subsidiary claim that Ẹ̀dó needs to distinguish bare predicate roots with the diacritic labels "verb" versus "adjective" (pace Baker 2003).

BK1 alias 'Proto‑Potou‑Akanic‑Bantu' — a study of diachronic syntax
Department of Linguistics, University of Ghana, Legon, 6 October 2010.
[handout, 9 pp. A4]
ABSTRACT: John Stewart's many studies of Àkan yielded general findings about Niger‑Congo, including synchronic diagnostics of serial constructions (1963) and historic soundshifts (2002). Read together, his oeuvre confronts a more abstract issue: how phonology and syntax interact i.e. whether they share formal properties (KLV 1985; Bromberger & Halle 1989; Scheer 2008). In principle, language‑specific information could be transmitted on multiple, parallel paths; in practice, "external evidence" (Kiparsky 1971) decides. Since Westermann (1927) it's been unknown how to reconcile the strong diversity of the area later called Kwa and Benue‑Congo (Greenberg 1963; Williamson 1989) with weak lexical reflexes of historical discontinuity; three proposals are compared. Large‑scale dialect continua may well exist in general, but some restructuring must separate the agglutinating and isolating extremes subtended by Stewart's "Potou‑Akanic‑Bantu" (PAB); the task is to find causal chains and see whether various components of grammar shifted in synch. As it happens, PAB's reconstructed 4‑way stop contrast was reduced by half in BK2, and this 'catastrophic' phonetic change is matched by a fourfold mutation of grammar, with two inaudible interpretive traits, one piece of audible morphology and something traditionally but mistakenly considered as narrow phonology. The trigger for the lot, thus for bifurcation of PAB=BK, was arguably suffix erosion, a language‑external process (Manfredi 2005, 2009).

ABSTRACT: The device of "tonal morphemes" (Welmers 1959), a type of "featural affixation" (Akinlabí 1996), has been much applied in taxonomic and generative analyses of Niger-Congo languages, but it can't express nonlocal prosody. For example in Ìgbo object relative clauses, an obligatory and lexically spurious H tone marks the right edge of the crossed-over remnant subject:
íhe Ùgó [LH] mère __    'what Ùgo [LL] did __'
(Swift & al. 1962, 247f., 303ff.; Green & Ígwè 1963, 88; Welmers & Welmers 1968a, 152; Nwáchukwu 1976a, 102ff.). In a constructional analysis, this token of H has no conceivable morphological mechanism, but the matter appears differently in the architecture of Minimalism (Chomsky 1993), where representational levels are restricted to bare interfaces mapping internal syntax (i-language) to grammar-external modules of acoustic phonetics (PF), logical pragmatics (LF) and the lexicon (LRS), entailing that tonal morphology is completely undefined. Yet despite—or because of—such theoretical restraint, the phenomenon at hand is tractable under derivation-by-phase (Chomsky 2001, Dobashi 2003, Scheer 2008, Richards 2010) where it qualifies as direct phono-semantic SpellOut in the form of a cyclic accent, isomorphic to Germanic Nuclear Stress (Chomsky & Halle 1968, Bresnan 1971, Kiparsky 1979, Cinque 1993, Zwart 2004, Wagner 2005, Zubizarreta & Vergnaud 2006). This unexpected result has the further consequence to vindicate the reduction of tonemes to scalar (e-language) output (McCawley 1964, Clark 1978, Zubizarreta 1982, Odden 1985, Sietsema 1989, Purnell 1997, Kimenyi 2002, Dilley 2005), reinforcing the recent and reluctant retreat from tonal phonology by some leading autosegmentalists (Clements & al. 2010, 20f., Hyman 2010). Nothing viable or necessary then remains, not just of tonal morphemes per se, but even of the traditional concept of tones as exotic, phonemic quanta of paradigmatic minimal pitch contrast (Jones 1928, Chao 1930, Pike 1948, Williams 1971, Goldsmith 1976, Poser 1984, Clark 1989, Odden 1996, Hyman 2009 among many others).

ABSTRACT: Áfa and Ifá are two out of of many localizations of a farflung West African 'oracle' (spanning system capabilities of information retrieval and Llullian ars combīnatōria) whose digital processor keys natural language text to 256 ordered pairs of 4‑bit arrays (ordered binary sets), cf. Fo̩̩rúnso̩ & Akínwálé (2009). While being ported south and west from the Benue rivervalley some 500 years ago, the oracle's own name and other proprietary terms underwent sound change in the receiving languages. These phonetic shifts, plus paralinguistic mutations, remain behind as footprints on the transmission routes. The texts themselves and their uses also evolved along their branching path, as emergent élites turned from ancestral legitimation rooted underground, to novel ideas of authority dangling from the sky.

ABSTRACT: A scholarly reincarnation of Egharhevba's Ìha Ominigbo̩n (1936) is long overdue. This Ẹ̀dó classic has intrinsic value as cultural description but is virtually unobtainable today and readable only with difficulty. It's also relevant to wider historical relationships — even if not in the Ifè̩-centric way intended by its author — and requires critically-informed translation for both academic and popular access.

Preliminary comparisons with Yorùbá Ifá and Ìgbo Áfa show that Ẹ̀dó Òminigbo̩n — alias Ìha — breaks the presentist mold of an encompassing "Yorùbá-Ẹ̀dó world system" (Ògúndìran 2003, 57, cf. Burton 1863, 222). Ìgbo etymologies exist for core Ìha terms ògwé̩è̩ga and n'áàbe, as well as for "Ogbẹide" — the second appellation of the person who introduced the system to Ẹ̀dó (Egharhevba 1936, 3, no tone indicated). Respectively, the Ìgbo sources are òkwé è̩ja 'oracle seeds', n'áàbo̩ 'double' and ò-gbú ìre '[performing/possessing] very effective [sacrifices/medicine]'. An Ìgbo source is independently plausible from comparison of Òminigbo̩n's casting method with those of Áfa and Ifá (Emọvọn 1984, Ọ́nwụejìọ́gwụ̀ 1978, Abím̄bọ́lá 1976). Transmission from Ìgbo to Ẹ̀dó is also consistent with evidence of loanword phonology as to how oracle-specific jargon crossed the southern 9ja area in medieval times (Manfredi 2009a). Obvious matches between the 256-part semantic keys of Áfa and Ìha surpass 35% — well above chance similarity — though it is harder to measure the extent of Ẹ̀dó innovation in the remainder, as well as in the relationship between Ẹ̀dó oracle narratives (èría no̩ dìmwín) and their functional counterparts in Yorùbá (e̩se̩ Ifá parts 2-6) and in the Gbè-speaking area (Maupoil 1943a, Kligueh 2011b).

These observations and a long list of others support the view that Yorùbá oral history has "confused Odùduwà with Ọ̀rúnmìlà" (Erediauwa 2004, 206) in the thrall of Ifẹ̀-centric narratives motivated by the modern politics of 9ja, the Nàìjá area, colonial "Nigeria" (cf. Ryder 1965; Vansina 1971, 457; Law 1973; Ọbáyẹmí 1979). The advanced codification of Ifá as compared to its 9ja relatives shows the mnemonic bias of several arguably modular cognitive domains — number, folk biology, folk sociology, theory of mind — plus the nonmodular but eminently memorable "genius of paganism" (Augé 1982) and its "superstimuli" (Sperber & Hirschfield 2004, 45).
UPDATE 12 January 2013: On Saturday 5 January 2013, the boss of Ifẹ̀ Central Local Government joined General Akínrìnádé and the Ọọ̀ni at "the commissioning of the gigantic Orí Oló.kun edifice […] at the Mayfair Roundabout" (Adéṣìnà 2013). This is the very spot where 9ja police (alias Sorrow, Tears & Blood) fatally stampeded a peaceful anti-Ṣíjúwadé protest on Sunday 7 June 1981 (cf. §3.5 of my paper). Public doubling down on the Frobenius myth shows the force of Wazobi̩an consciousness; in the same vein, Olúpọ̀nà (2011).

UPDATE 14 April 2014: Prof. Akin Oyèébò̩dé, progressive eminence of international law at the University of Lagos, explains in this engaging interview (20 min.) his recent proposal at the improvised and unsovereign National Conference to drop the name "Nigeria" because of its dubious colonial antecedents, its negative notoriety acquired during the past 54 years and its indelible etymological association with the "N‑word" of racist usage.
UPDATE 30 April 2015: Incomplete English translations of 73 chapters of Ìha Ominigbo̩n, prepared on request by Jeff Ò̩̩ruyì (Benin-City), can be read here alongside the second edition of Egharhevba's È̩dó text. The unfortunate disappearance of the first edition (1936) from public record leaves unexplained numerous obscurities and inconsistencies of the 1965 text — not to mention a dozen mysterious Bible interpolations!

ABSTRACT: Argument nP freely accesses unlexicalized referential D in certain languages (Cantonese, Wenzhou, Yorùbá, Gbè) but not in others (Mandarin, Taiwanese, Ìgbo, Haitian respectively) which are pairwise closely similar but whose lexical roots fall below a ternary threshold of prosodic complexity (§1). Consequences of this unexpected generalization are independently necessary.

At PF (§2), if 'more tones' cue 'more structure' then lexical tone is not phonology (pace Pike 1948; Goldsmith 1976; Ladd 1996) and/or phonology is not 'different' (pace Bromberger & Halle 1989). Instead, lexical tone is the pitch effect of metrical accent with phrasal distribution (Idsardi & Purnell 1997; Déchaine 2001) i.e. lexemes are phrases (Hale & Keyser 1993), and ternary tone makes available an 'extra' level of phrasal branching beyond what is required to host segmental material of the numeration.

At LF (§3), the minimal free form in Yorùbá, e.g. a notional noun like ajá 'dog', is at least nP (cf. Welmers 1973a, 189f.). But argument ajá is not a bare singular: it can refer to indefinite plural individuals, which its counterpart the Ìgbo animate nP cannot (Welmers 1973b, 220). In object position, the Mandarin nP (sortal classifier plus root) can only be indefinite singular, whereas root N (without SORT) is definite singular or (in)definite plural but not indefinite singular (Yang 2001, 29). The foregoing differences follow if so‑called 'little n' of an Ìgbo animate count noun like òké 'rat' is featurally singular, whereas Yorùbá little n is defective, being the pure spellout of an empty phrasal node but still with the status of a typed category, and Mandarin root N exploits pseudoincorporation and object pro drop. Yorùbá allows generic readings in episodic contexts with phonetic elision of semantics‑less little n as a pseudoincorporation cue, just as in Mandarin a similar interpretive effect is blocked by an overt classifier (Huang 2005). Ìgbo little n is not elidable under any circumstances, but Ìgbo makes episodic generics in a different way: in caseless configurations, nP is pseudoincorporated and not indefinite singular (Déchaine & Manfredi 1997). In addition to the foregoing, an unadorned nP can be definite in the ternary languages independently defined in §1. No alternative account of these generalizations is currently available.

As to learnability (§4), the varied conditions for free null D resist encoding as an abstract invariance/isomorphism of the computational system alias UG, but such failure is no loss, because the factorization of syntactic differences as (micro or macro) I‑language parameters is unfeasible on general grounds (Keenan & Stabler 1994, 2003). In Sinitic and Benue‑Kwa, the limits of possible mapping between referential and prosodic type in argument expressions can be modeled in the left‑peripheral prosodic template known as "the initial site" (Lowenstamm 1999), consistent with "inter‑modular argumentation" (Scheer 2010).
UPDATE: Literature on category determination at spellout, consistent with the architecture of argument‑type expressions ("substantives") developed in this paper, according to which the semanticist's notional "nouns" are not lexical heads, now includes:

UPDATE 2: For further reduction of semantic types to syntactic derivation, building on Longobardi's (1994, 2005) topology, see

Sheehan, M. & W. Hinzen. [2011]. Moving towards the edge [free manuscript version]. Linguistic Analysis 37, 405‑58. [ISSN 0098‑9053]

The PF side of their generalization that "the more 'edge-heavy' a phrase becomes… the more referentially specific…" (p. 408) helps to explain the Longobardian but article‑less patterns of prosodic 'activiation' of the D‑layer in both Benue‑Kwa and Sinitic, as reported in my paper and schematised in examples (91) ‑ (92). This makes sense only so far as ternary prosody is intrinsically 'heavier' than binary prosody (e.g. in terms of greater branchingness, assuming accentual reduction of tone).

ABSTRACT OF ABSTRACT: Before the British Anschluss, various Ìgbo-speaking communities and their neighbors deployed an ideographic (nonphonetic) initiation code of gestures and graphic designs which by nature had no need to represent "tone" (lexical contrasts of perceived laryngeal pitch or fundamental frequency). With alphabetic literacy came no less than four tonemarking techniques, all of which remain in use for different purposes, and this multiplicity of means uncannily fits the watchword of "strength in numbers" (ìgwe bu̩ íke) which is proverbial in the southeast angle of the 9ja geopolitical hexagon. Wahlverwandtschaft aside, this abundant methodological diversity is not about to be simplified by a (nonexistent) central planning office, and there's no imminent prospect of Ìgbo linguists, far less speakers, spontaneously settling on a single style of encoding linguistically significant prosody that's unrecoverable from immediate context. This abstract (and the substantive paper to which it points) reviews the clashing strengths and weaknesses of each type of tonemarking for various purposes — all of which are legitimate functions that Ìgbo literates may want to use. Apparently the only exit from the present muddle demands a more adequate theoretical approach to Ìgbo prosody than linguistic science can offer right now, combined with a greater practical commitment to public education and media access than is possible in the collapsing political economy of a vanquished province of a neoliberal neocolony.

UPDATE 12 December 2012: Recent grandstanding by a couple of southern white male Republican senators about snafus in Obama's "Arab spring" catchup game in Libya has inadvertently renewed public attention on Susan Rice's official as well as covert benevolence to client African dictators throughout her ascent of executive‑branch appointments in the past 20 years (interspersed with lucrative corporate lobbying). The most discussed examples are special favors to civilian‑clothed avatars of Generals Meles and Kagame, whereas similar indulgences to Generals Abacha and O̩básanjó̩ have scarcely elicited a mainstream peep, despite U.S. planners' "failed state" scenario of Nigeria "dragging down a large part of the West African region". Whether Clintonesque financial "conflicts of interest" have been in the last analysis either more or less determinant than power intoxication of the kind displayed on TV by her mentor Madeleine Albright, in explaining Rice's repeated record of framing/implementing shameful U.S. sellouts of the populations enclosed within the nominal boundaries of Nigeria, Ethiopia and Rwanda/Congo, is less certain than that the present scandal provides a teachable moment for anyone who wants to know why Africa "still dey suffer today".
UPDATE 20 April 2015: The perennial theme of "a pattern of financial transactions involving the Clintons that occurred contemporaneous with favorable U.S. policy decisions benefiting those providing the funds" is reviewed in a forthcoming book appropriately entitled Clinton Cash. Even if the study's coverage of the Clinton Foundation does not reach back to the Chagoury era, the pattern remains constant of presumptive influence-peddling to indulge resource-extraction industries and third-world dictators at the expense of immiserated indigenous populations — precisely the Abacha situation referenced here.

Phase bifurcation — causes and consequences in Benue‑Kwa (Niger‑Congo)
Departamento de Lingüística, Universidade de São Paulo, 22 April 2009
[handout, 8 pp. A4, last modified 2 July 2009]
ABSTRACT: Benue‑Kwa (BK), the main branch of the Niger‑Congo family, is an 'epigenetic' (or non‑parametric) typological space (Gianollo & al. 2008; cf. Keenan & Stabler 1994; Newmeyer 2004) created by interaction of the internal and external dimensions of the human language faculty (I‑ and E‑language, Chomsky 1986). §1 reviews a timing shift in cyclic spellout — the derivation‑internal branching to PF — apparently triggered by external factors (Manfredi 2005, 2009a). In the remnant area (BK1) the lowest spellout domain is TP, including finite inflection aligned on or after the predicate root, but in the innovating area (BK2, including Gbè, Yorùbá‑Igálà, Nupe‑Ebira and Ìdọmà) the lowest domain contains only open‑class predicators, thus is no bigger than VP, leaving closed‑class clausal superstructure to a separate, subsequent phase. §2 considers the mechanism of this bifurcation and the status of prosody therein as either determinant or determined. The initial state, today represented collectively by BK1, allows at most binary 'tone' (lexical discrimination of roots by pitch), whereas this contrast is at least ternary throughout BK2. Some BK1 languages (Ẹ̀dó, Western Ìgbo) maintained late spellout even after obligatory finite suffixation had eroded to zero; short of appealing to analogy with optional suffixes, the only explanation is externalist and accidental: acquisition in BK2 of early spellout was triggered by a ternary lexical pitch contrast, most likely pushed by phonation effects which are still transparent in Gbè (Stahlke 1971). Such an inference is ruled out by standard views of prosody as "phonology" (Nespor & Vogel 1986; Ladd 1996) and of phonology as "different" (Bromberger & Halle 1989), but is supported by syntagmatic/metrical analysis of 'tone' (Bamba 1992; Manfredi 1995a,b; Dilley 2005a,b,) and also on statistical grounds both in BK and in Sinitic (Manfredi 2009b). §3 claims that other cross‑BK differences are incidental to phasing: not just the pragmatic (narrow‑semantic) contrasts discussed in §1, but also certain options of overt morphosyntax: in‑situ variables, affixal anaphors and marked accusatives in BK1; modals, inverse copulas and marked nominatives in BK2. All these would standardly be treated as independent parameters, but within the BK typological space all are arguably contingent on prosody as understood in §2.

Cyclic accentuation in Yorùbá
To appear in Data-rich Linguistics; papers in honor of 'Yíwo̩lá Awóyalé, edited by A. Akinlabí & al. Cambridge Scholars Publishing, Cambs., England.
[prefinal proof, 24pp. A5, last modified 15 January 2017]
ABSTRACT: In Standard Yorùbá phonology, lexically spurious H tone marks each cyclic node, like English nuclear stress (Bresnan 1971, Cinque 1993, Wagner 2005, Zubizarreta & Vergnaud 2006). Squaring this fact with assumed tonal autonomy forces a choice between two ad hoc analyses: either (i) amnesty all spurious Hs as homophonous "tonal morphemes" (Welmers 1959) or else (ii) sprinkle them as pitch accents into an unrestrictive "autosegmental-metrical" mix (Ladd 1996). But the circularity is avoidable, because tones are generative impostors, first induced by structuralist discovery procedures (Jones 1928, Chao 1930, Pike 1948) then pasted wholesale into formalist notation (Williams 1971, Leben 1973, Goldsmith 1976). The critique of taxonomic phonemics (Halle 1959, Chomsky 1964) should favor the derivational theory "…that it will not be possible to classify languages into 'tone languages' and 'languages with pitch accent system' in any non-arbitrary way, but it will be possible to speak of a language as having a pitch accent system up to some point in the ordering of its rules and having a tonal system from that point in the rules on" (McCawley 1970, 529). Forty years later, Clements & al. finally concede the argument "against universal tone features" and accept that the role of perceived pitch in human language is limited to "monodimensional… scales… directly interpreted in the phonetics" where "observed patterns of alternation… are typically random and arbitrary" (2010, 20f., cf. Hyman 2010, pace Hyman & Schuh 1974).
