takʷ n. horse cheval (5 groups, 10 languages) B syn: pɨrɨs ʸ, bɨskʷan.
This is one of three main roots for 'horse' in Central Chadic. There is an irregular change *t→d in Proto-Daba and Sukur, and the sporadic change *kʷ→hʷ in Proto-Bata.

taɬ v. to be cold être froid (8 groups, 12 languages) A cf: hɨmɨɗ ʸ.
This word probably had a verbal sense 'to be cold', which gave rise to nominal forms, many of which are cited here. The root *hɨmɨɗ ʸ 'wind' is also used for the concept 'cold' in many languages. *ɬ should have the reflex *ɮ in Proto-Mafa, but *ɬ is found.

tasɨraɗ num. seven sept (3 groups, 12 languages) A syn: mɨɗɨp.
This root is less well-attested than *mɨɗɨfɨn. It is found on or around the Mandara Mountains. There is a regular change *r→l in the North sub-branch, of which the Mofu group is part, and in Cuvok. The same change took place in the Daba group, but that is not evident in the limited data here. The final *ɗ has been lost in the Mofu group, which is a common sporadic change.

tip v. to spit cracher (14 groups, 31 languages) A
This common root is almost certainly onomatopoeic in origin. A similar word is found in both Hausa and Kanuri. It is significant though that *i is present in almost all the groups where this vowel is part of the phonemic inventory. This implies that the word may have been adopted as a word rather than as a sound at an early period in the history of Central Chadic. *p was realised as [f] word-finally in Proto-Central Chadic, so the presence of the final *f in all groups does not contradict the early origin of the word.

tira nm. moon lune (10 groups, 31 languages) A syn: kɨja.
This root is the original Proto-Central Chadic root, and goes back at least as far as Proto-Chadic. There is a regular change *r→l in the North sub-branch, though here Proto-Higi has *r, and Proto-Kotoko North and Proto-Kotoko Centre have *ɗ. It is expected that Sukur has /r/, but this is not the case. Evidence for *i comes from the three groups where *i exists as a phoneme, i.e. the Mandara, Lamang and Higi groups. In Glavda, *i has been reanalysed as the palatalisation of *t. There is a regular process in Glavda where palatalised alveolar consonants become palatalised velar consonants, and this explains the presence of /kʲ/. The change *t→k in Muskum is regular.

tɨɣis num. eight eight (4 groups, 11 languages) B
It is unlikely that Proto-Central Chadic had a root for 'eight', This is the most widely attested root, and it is only present in four groups. These groups are not genetically related at a close level, so the root may be a comparatively recent coinage that has spread.

tɨma nm. sheep mouton (11 groups, 34 languages) B
Sheep farming probably did not take place amongst the Proto-Central Chadic speaking people. The word entered Central Chadic at a later point. Many languages have either /-ŋ/ or /-k/ suffixed to the root. These could be historic gender suffixes which have become fossilised. The change *m→w took place in the Mandara group as a regular change in word-final position, but it is not expected in intervocalic position. In the Lamang group *m
→w was a sporadic change. In several languages there has been a sporadic change *m→ᵐb. The /ɓ/ found in Proto-Tera and in the Mofu languages is probably a development *ᵐb→ɓ. In Mandara and Malgwa the *i has palatalised the *t. There is a regular process whereby palatalised alveolars become palatalised velars in these languages, giving /kʲ/ in these languages.

tɨsaw v. to roast rôtir (5 groups, 10 languages) A cf: d, sɨwra.
The basic meaning of this word is to cook food in a fire. It contrasts with *sɨwra 'to fry'. *d is a generic term for cooking. The *w has resulting in the creation of the vowel /u/ in Muyang, Gemzek and Giziga Marva, creating exceptions to the general rule of vowel harmony.
