3.1 Segments 27
Because of the variation between [d:] and [t:] as geminated counterpart of
d, we must accept that d and t are partially independent of each other as
phonemes. Moreover, there are a number of borrowings with ungeminated t,
e.g. VblN a-talla? 'making a profit' (<Arabic). I will therefore transcribe with
d or t based on pronunciation. In extracting consonantal "roots" for dictionary
alphabetization purposes, I use the conventions summarized in (20).
(20) "Root" Consonant Extraction Conventions for d and t
d a) for word-families that have at least one form with phonetic
[d], Example: Vdf 'seize, hold' because of VblN udaf.
b) for word-families where the relevant consonant occurs
only in [tX] clusters (where X is a voiceless obstruent),
so at least arguably the [t] is a /d/ devoiced by a CC-
cluster voicing assimilation rule.
t c) for word-families with [t] in at least one form where it is
ungeminated, and either prevocalic or before a voiced
consonant. Example: tabael 'table',
d) for word-families with invariant geminated [t:] with no
direct evidence for/d/. Example: t-aettael 'roasted meat'.
3.1.1.5 Alternations of s and ζ and of s and zz
The popular subdivisions of Tuareg (Tamashek, Tamajak, Tamahak) are
named after the predominant reflex of *z. Within the Tamashek dialects
studied, there are some interesting synchronic variations of s with ζ (this
section), and others of s with ζ (§3.1.1.6, below). As noted in §3.1, s is
pronounced hy in some Kidal-area dialects.
In (21), I list the stems known to me that vary subdialectally (sometimes
with more or less free variation within a subdialect) between forms with s and
forms with z, across most or all stems in the word-family.
(21) Dialectal s/z Alternations
a. Vshr and Vzhr 'be massive, well-fed'
b. Vsj and Vzj 'chase away'
c. Vsjr and Vzjr 'long, tall' (also Vsjr)
For 'be massive' we get e.g. MaSg participle ("adjective") suhaer-aen or
zuhasr-asn. For 'chase away' we get e.g. PerfP -asaej- varying with -szaej-. For
'long, tall' we get e.g. MaSg participle saejre-n varying with zaejre-n. In these
word-families, the s variant is the more common overall. For 'long, tall' I have
