	Jê languages proper (clear yellow) and other Macro-Jê languages (dark yellow) in modern times. Shadowed area represent approximately extension in the past.

The Jê languages (also spelled Gê, Jean, Ye, Gean), or Jê–Kaingang languages, are spoken by the Jê, a group of indigenous peoples in Brazil.

Genetic relations

The Jê family forms the core of the Macro-Jê family. Kaufman (1990) finds the proposal convincing.

Family division

According to Ethnologue (which omits Jeikó), the language family is as follows:

Jeikó (†)
Northern Jê
- Apinayé (2,300 speakers)
- Mẽbengokre (Kayapó) (8,638 speakers)
- Panará (Kreen Akarore) (380 speakers)
- Suyá (350 speakers)
- Timbira (Canela-Krayô, with the Canela and Kreye dialects) (5,100 speakers)
Central Jê
- Acroá (†)
- Xavante (9,600 speakers)
- Xerente (1,810 speakers)
- Xakriabá (†)
Southern Jê
- Xokleng (760 speakers)
- Kaingáng
  - Kaingáng (18,000 speakers)
  - São Paulo Kaingáng (†)
  - Ingain (†)
  - Guayana (†)

Ramirez (2015)

Internal classification of the Jê languages according to Ramirez, et al. (2015):^[1]

Jê

Southern Jê (dialect continuum)
- Ingain ↔ Xokleng ↔ Kaigáng
Northern Jê
- Jê proper (Timbira-Kayapó dialect continuum)
  - Canela-Krahô ↔ Gavião-Krĩkati ↔ Apinajé ↔ Kayapó ↔ Suyá-Tapayuna ↔ Panará-Kayapó do Sul
- Akuwẽ (various microdialects)
  - Xavante
  - Xerente (including Xakriabá, Akroá, Gueguê)

Ramirez excludes Jaikó as a possibly spurious language.

Nikulin (2020)

According to Nikulin (2020), the internal branching of the Jê language family is as follows:^[2]^[3]

Some sound changes and lexical innovations that define various Jê subgroups:^[4]

Proto-Southern Jê *a < *Proto-Jê *ô
Proto-Cerrado *wa < Proto-Jê *ô
Proto-Goyaz Jê: *am, *um, *ɨm > *ãm, *ũm, *ɨ̃m
- Proto-Northern Jê: replacement of *kakũm ‘dry season’ (as in Panará akũŋ and Proto-Central Jê transl. mis – transl. '*wahum) with *aŋgrə
- Proto-Timbíra: *c > *h
- Proto-Trans-Tocantins: replacement of *a-mbə ‘eat (intransitive)’ with *ap-ku
