The Akuwẽ[1]: 12–4 or Central Jê[2]: 547 languages are a branch of the Jê languages constituted by two extant languages (Xavánte and Akwẽ-Xerénte) and two extinct or dormant, scarcely attested languages (Xakriabá and Acroá).[3] Together with the Goyaz Jê languages, they form the Cerrado branch of the Jê family.

Phonology
The Akuwẽ languages share a number of characteristic innovations, such as the Akuwẽ/Central Jê vowel shift,[4]: 61 [5]: 164 the sound change *ka- > *wa-,[5]: 161 [6]: 70–1 and the occlusive merger,[5]: 159–161 which distinguish them clearly from all other Jê languages.
A characteristic feature of the Akuwẽ languages is the existence of complex allomorphy patterns whereby the choice of the allomorph is conditioned by the position of the word within a syntagm (i.e. whether the word is in the middle or in the end of a syntagm).[7]: 139–43 It has been suggested that it is possible to derive both allomorphs (those that occur syntagm-internally and those that occur syntagm-finally) from uniform underlying representations, which involve underlying codas.[5]: 155–168
Historical development
The onsets of Proto-Cerrado have evolved in the following way in Proto-Akuwẽ.
| Proto-Cerrado | Proto-Akuwẽ | ||||
|---|---|---|---|---|---|
| oral nucleus | nasal nucleus | oral nucleus (Proto-Cerrado non-high vowel) |
oral nucleus (Proto-Cerrado high vowel) |
before a diphthong | nasal nucleus |
| *p */p/ | *p */p/ | *b */b/ | N/A | *m */b/ | |
| *mb */m/ | *m */m/ | ||||
| *pr */pɾ/ | *pr */pɾ/ | N/A | *mr */bɾ/ | ||
| *mbr */mɾ/ | *mr */mɾ/ | N/A | |||
| *w */w/ | *w */w/ | ||||
| *t */t/ | *t */t/ | *d */d/ | *∅ | *n */d/ | |
| *nd */n/ | *n */n/ | N/A | |||
| *r */ɾ/ | *r */ɾ/ | *∅ | *r */ɾ/ | ||
| *c */c/ | *c */c/ | *ĵ */ɟ/, *h */h/ (before *i) | *∅ | *c */c/ | |
| *nĵ */ɲ/ | N/A | N/A | |||
| *j */j/ | *ñ */j/ | *ĵ */ĵ/, *c */c/ (before *i) | *k */k/ | *ñ */ĵ/ | |
| *k */k/ | *k */k/ (unstressed *ka- > *wa-) |
*h */h/ | *∅ | *k */k/ | |
| *ŋg */ŋ/ | *ŋ */ŋ/ | N/A | |||
| *kr */kɾ/ | *kr */kɾ/ | *kr */kɾ/ | |||
| *ŋgr */ŋɾ/ | *ŋr */ŋɾ/ | N/A | |||
| *g */g/ | *g */g/ | N/A | |||
Note that the onsets *p, *t, and *k(r) are synchronically found preceding not only non-high oral vowels in Proto-Akuwẽ, but also preceding innovative high vowels (*i, *u < Proto-Cerrado *ê, *ô) and nasal vowels (such as *õ, *ə̃ < *u, *a). The reflexes *b, *d, and *h are found preceding only those vowels that were already high in Proto-Cerrado.
Lexicon
Predicate number
The Akuwẽ languages commonly employ different lexemes for singular, dual, and plural predicates.[8][9][7]: 203–7 Although the lexicalized expression of verbal number is pervasive in the Jê family in general, the Akuwẽ languages are remarkable in having triads (rather than dyads) of verbs contrasting in number.
