ᵐbaɮa nm. beer bière (7 groups, 14 languages) A syn: ɣʷɨzɨm, vɨhʷ.
This is one of three widespread roots for 'millet beer'. It may be cognate with the Kanuri ᵐbal. If so, it is more likley that the Kanuri borrowed from Central Chadic than vice versa. If the word was borrowed from Kanuri, the change *l
→ɮ would have been natural at the time of Proto-Central Chadic when *l was not a phoneme in the language. *l developed in Proto-Central Chadic North as a result of the regular change *rl, so if the word was borrowed into Central Chadic after that time the change would have been unnatural. For this reason it is more likely that this is a native Central Chadic root.

ᵐbatuɓ n. baobab baobab (4 groups, 6 languages) C syn: kʷɨkaɗ.
This root is far less widespread than *kʷɨkaɗ. It is problematic in that it contains a back vowel, and back vowels were not present in Proto-Central Chadic. It must be assumed that this root was either coined in Proto-Mafa, or else was borrowed into the languages of the Mandara Mountains at an early stage.

This root has the basic sense 'to change', with extended meanings including 'to turn', 'to exchange', 'to translate' etc. There was a regular word-final change *ɗ→r in part of the Higi group, but otherwise this root has been transmitted largely unchanged.

ᵐbɨkʷɨm n. horn corne (4 groups, 7 languages) C syn: lagan, dɨrɨm, mahʷa.
This is one of the less common roots for 'horn'. The roots given come from three very distant areas, so this may be a root which had a far wider range, or it may be that this word exists in more languages but hasn't yet been recorded, or else these may simply be chance similarities.

1Proto-Tera *ᵐbaʔʷamⁿda horn corne 1.1) Gaʼanda (Gwaji) ᵐboʼomⁿda animal horn

ᵐbɨlala ʸ n. elephant éléphant (3 groups, 6 languages) A syn: dzɨwɨn ʸ, gɨwɨn, nɨvi.
This root is found in five contiguous languages, and in Tsuvan which is very distant from these languages. The Tsuvan root follows the right patterning to be the result of contact with the other languages, but the physical and genetic distance between it and the other languages makes it more likely that this is a chance similarity.

ᵐbɨr v. to get well guérir (6 groups, 17 languages) A
This verb has the sense of getting better after an illness, and can be used transitively with a human object for curing a person of an illness. The *r→l in the North sub-branch and in Proto-Daba is a regular change. The change *r→ɗ in the Bata group is an irregular change.

ᵐbɨw v. to give birth accoucher (3 groups, 9 languages) C syn: wahaj.
This is the less common of the two roots for 'to give birth'. The Proto-Musgum root is possibly cognate, but more likely to be a chance similarity.

ᵐbɨwran nm. tamarind tree tamarinier (10 groups, 28 languages) B
This, along with the baobab, is one of two tree species reconstructed for Proto-Central Chadic. There was a regular change *r→l in the languages of the North sub-branch and Cuvok, and in Sukur as an irregular change. In the Mandara group, Podoko has the expected /l/, but the other languages have /r/, which is unestablished. The final consonant presents problems. It is *m in Proto-Mafa, Proto-Sukur, Proto-Maroua and Proto-Lamang, *ŋ in Proto-Higi, *r in Proto-Mofu and absent in Proto-Margi and Proto-Mandara. There is a regular change *n→r word-final in the Margi-Mandara-Mofu major group, which accounts for the final *r in Proto-Mofu if the final consonant was originally *n. The absence of *r in Proto-Margi and Proto-Mandara may possibly be due to a constraint forbidding adjacent *l and *r, though this constraint has not been established. The presence of *m as the final consonant in the other groups is irregular. *w is reconstructed to account for the widespread presence of /u/ in groups where the proto-language had no back vowels.
