kaligimo n. camel chameau (3 groups, 6 languages) A syn: ɮɨgʷamɨ ʸ, ᵑgʲaluba.
This root is a borrowing from the old Kanuri /kaligimo/, and is found in three of the Kotoko groups. There were no back vowels in these groups at an earlier point in their history, and this has led to the displacement of the back vowel next to velar consonants in Lagwan, Mser and Mazera. The back vowel was reanalysed as labialisation of the velar consonants, which then condition a following *ɨ to be realised as [u].

katakam n. mouse mouse (3 groups, 4 languages) B syn: kʷɨhɨm, kʷɨsɨm.
This root is found in a few languages in the south-eastern part of the Central Chadic area. The labialisation prosody in Proto-Maroua is a common sporadic innovation in that language.

kɨdɨm nm. crocodile crocodile (11 groups, 33 languages) C syn: rigɨ.
This well-attested root is surprisingly difficult to reconstruct. It is probably borrowed from Nilo-Saharan at an early stage of the history of Central Chadic, but does not come directly from the Kanuri 'karam'. The initial *k has the unestablished reflexes *g in Mbuko and some of the Mofu group languages, and *h in Proto-Musgum. *d is reconstructed as the second consonant. There was a change of word-medial *d→r in the North sub-branch, though the *d is not retained in Proto-Bata or Proto-Sukur. The presence of *d coincides with the presence of *g. The original root may have been *gɨdɨm, and developed into *kɨrɨm in the North sub-branch, and then the two competing roots spread between languages at a later stage. Alternatively, two different cognates may have been borrowed into Central Chadic from different directions. In Proto-Mandara, the final *m has become *w as part of a regular change.

kɨja nm. moon lune (7 groups, 23 languages) A syn: tira.
The basic sense of this root is 'moon', but it has the extended sense 'month' i.e. a period of time, in almost all languages. This is one of two roots for 'moon', with *tira being used widely across Chadic languages. The *k is realised as *h in Proto-Margi, an unestablished change, and also in Zina where this is a regular change. In some Mofu group languages the *j has triggered the creation of the palatalisation prosody, which is a common sporadic process.

kɨɬɨɗ n. broom balai (5 groups, 9 languages) D syn: sɨmɨt ʸ, sɨrɨkʷ.
This root is found in a mixed group of languages. This, and the variation in the reflexes, make it uncertain that these are all cognate. The word is undoubtedly an innovation that was not in use in Proto-Central Chadic.

kɨr v., n. steal voler (16 groups, 49 languages) B
This is one of the best attested roots in Central Chadic. Some of the entries are for the verb 'to steal', and some are for the nouns 'theft' and 'thief'. It is not clear which form is the basic root. The *k has the reflexes *h, *hʷ, *ɣ and *ɣʷ, which are unestablished reflexes. No labialisation is reconstructed since the support comes only from an unusual reflex in Lagwan, and from the Giziga languages where sporadic labialisation is common. It is not clear whether the proto-form had *h or *k, but *k is preferred as *k→h is more common than the opposite change in Central Chadic. The *r has the regular reflex *l in the North sub-branch and Proto-Daba. The *r in Proto-Kotoko North is an exception. In a few languages *r has the reflex /ɗ/, which is an unestablished change. There is some evidence for reconstructing *i, but the mix of noun and verb forms makes it difficult to reconstruct the vowels with confidence. For this reason the root is given the confidence level B rather than A.

kɨri nm. dog chien (13 groups, 35 languages) C
This root may have come into Central Chadic from Kanuri or from Nilo-Saharan. The root presents some unusual difficulties. *r has the reflex *d in some languages, and *l in others. If this root were a Proto-Central Chadic root, then we would expect *r→l in the North sub-branch, but this is the case only in a few groups, some of which have a separate, later *r→l change. A Proto-Central Chadic root with *d in medial position should give *r in the North sub-branch. There is a reasonable degree of consistency in this, but there are many exceptions. The best explanation for the forms is that the word entered Central Chadic at the time of the group proto-languages. The final vowel is reconstructed as *i, as in Kanuri, and this is reflected in Proto-Margi, Proto-Lamang and Proto-Higi. In the Higi group the *i has been reanalysed as palatalisation of *l.

kɨrɨp ʸ nf. fish poisson (15 groups, 46 languages) A
This is one of the best attested Central Chadic roots. The initial *k has the regular reflex *j in the Tera group, and the unestablished reflex /h/ in Vulum. There was a regular change *r→l in the North sub-branch, the Daba group and Cuvok in the Mafa group, though the /l/ in Mafa itself is irregular. *p was realised as [f] in word-final position in Proto-Central Chadic, and /f/ was then phonemicised, but in this word it has the reflex *p in Proto-Lamang and Proto-Higi. These are unestablished changes. The palatalisation prosody is retained in all groups where the palatalisation prosody exists.

This is one of three widely-attested roots for 'ten'. It is found in the area around the Mandara Mountains. The *r is expected to be realised as *l in the North sub-branch, but this is only the case for the Mandara group, and not for the Maroua and Mofu groups. In the Mafa group, /l/ is found in Mafa where /r/ is expected and /r/ is found in Cuvok where /l/ is expected. This indicates that the root may not be very old, and that it spread by borrowing rather than being inherited. The *w is variously interpreted as labialisation of *k or as the labialisation prosody.

This is one of four well-attested roots for 'six'. It has the widest distribution, and is the most likely candidate for the Proto-Cental Chadic root. The *w has been reinterpreted as labialisation of *k in several groups. The final *h has been lost in most groups. These are common sporadic processes. In common with some other numerals, a nasal has been prefixed to the root in most cases.

This is a widespread African root that may have come into Central Chadic from Kanuri. Many Central Chadic languages do not have back vowels, and the *o has been reinterpreted as labialisation of *k, the labialisation prosody or as the sequence /aw/. The *r has not changed in any languages, which indicates a very short time depth for the introduction of this root into Central Chadic.
