Kera is an East Chadic language spoken by 45,000 people in Southwest Chad and 6,000 people in North Cameroon.
It was called "Tuburi" by Joseph Greenberg, a name shared with Tupuri.
In Cameroon, Kera is spoken by small, isolated and scattered groups in the southern departments of Mayo-Danay (Wina commune) and Diamaré (Ndoukoula district) in the Far North Region. It is mainly spoken in Chad. In Cameroon, the main group is near the border, south of Viri. There are about 6,000 speakers in Cameroon.[2]
Kera is a subject–verb–object language, using prepositions. It uses exclusively borderline case-marking.[citation needed]

Flap | ⱱ | ɾ |
Kera has a labiodental flap /ⱱ/, a rare sound attested in only 80 languages of the world. Out of the 60 or so words that contain this consonant, 95% of them are ideophones, which are sounds that evoke the very meaning of that word. Near-minimal pairs between the labiodental flap and the labiodental fricative /v/ exist: /vìw/ (hearing something pass by) and /ⱱīw/ (see something pass quickly).[5]
Kera allows almost all consonants to appear at the end of a syllable in word-medial position. However, At the end of a word as a whole, only the sonorants /l, w, j/ can occur. When a non-sonorant sound occurs at the end of a word, the vowel [i] is added at the end to avoid breaking this rule.[5]
Kera's syllables are relatively simple. It allows for a consonant to be followed by a long or short vowel and may take an extra coda consonant at the end. The initial consonant is optional in all cases. Additionally, there are several phonological rules at play that prevent consonant-vowel-consonant-vowel sequences from being possible. For example, [nèlɛ̀] and [fɛ́lɛ] are not allowed in Kera. To prevent these sequences from occurring, Kera will either lengthen the final vowel ([nèlɛ̀ɛ]), or remove the final vowel ([fɛ́l]).[5]
Kera has six contrastive vowels. In closed syllables, the mid and low vowels will undergo raising. Kera also has phonemic tones, whereby a change in pitch alone may differentiate words.[5]
