sɨhʷani ʸ n. dream rêve (15 groups, 37 languages) B
The *s has the reflex *z in West Tera as part of a regular change. The change *n→r in Proto-Kotoko North and Mser is a common sporadic change. *hʷ is realised as /hʷ/ only in Podoko. The reflex is *w in several groups, and the consonant has been completely lost in other groups. This is a common sporadic process. In Proto-Margi it has the irregular reflex *ʔʷ. The palatalisation prosody is easily reconstructed, with evidence from all groups. *i can also be reconstructed based on the evidence from the Bata, Margi, Mandara and Lamang groups.

sɨk ʸ n. leg jambe (3 groups, 15 languages) B syn: ʃi, sɨraj.
This root is only found in three adjacent groups. In Mafa, this root has the meaning 'foot', whilst the reflex of the root *sɨraj has the meaning 'leg'. In some languages of the Mandara group *k→g, which is an unestablished change.

sɨka n. field champ (3 groups, 5 languages) C syn: gʷɨvɨh, raj, ɣʷɨr.
This is the least widespread of four Central Chadic roots for 'field'. The great distance between the Bata group languages and the Kotoko languages makes it most probable that the forms presented here are not cognate.

This root is found in the south-west of the Central Chadic area. The *ᵐb has reflexes including /ɓʷ/, /w/ and zero, none of which are known to be regular. The root is difficult to reconstruct with confidence.

sɨmɨt ʸ nm. broom balai (9 groups, 16 languages) D syn: kɨɬɨɗ, sɨrɨkʷ.
This is one of three common roots for 'broom'. There is a high degree of inconsistency between the forms that are attested, which may be partly due to the fact that this root has only been found in one language in several groups.

1Proto-Bata *sɨmtɨ ʸ broom balai 1.1) Gude (Hoskinson) ʃíntá -ə broom 1.2) Sharwa (Gravina) ʃimtə balai

There was a regular word-final change *n→r in the Margi-Mandara-Mofu major group, though here Proto-Margi has retained *n. *n has been lost in Sukur, which is an irregular process.

sɨraj nf. leg jambe (12 groups, 26 languages) B syn: ʃi, sɨk ʸ.
This root is the most widespread of the roots for 'leg'. In Proto-Tera, *z is expected from a regular *s→z change, but *s is present. There is a regular change *r→l in the North sub-branch, the Daba group and in Cuvok. However, in the Mandara, Maroua and Higi groups we have /r/, and in Mafa we have /l/. In the Bata group *r has the unestablished reflex /ɗ/. *j has been reanalysed as *i in Proto-Margi and Proto-Kotoko North, a common sporadic process.

sɨrɨk ʸ n. jealousy jalousie (11 groups, 25 languages) B
This root, along with 'shame', is one of only two roots relating to emotional states that have been reconstructed. There is a regular change *s→z in Proto-Tera, and *r→l in the North sub-branch. *l is also expected in Proto-Daba, though *r is found. Support for the palatalisation prosody is not complete, but is present in most groups where it is a feature. The final *k has the reflex *h in some groups, and has been lost in others. This is an unestablished process. *n is found in its place in Proto-Maroua, which is also an unestablished change.

sɨrɨkʷ n. broom balai (5 groups, 13 languages) A syn: kɨɬɨɗ, sɨmɨt ʸ.
This root is found primarily in the Mofu group. There was a regular change *r→l in the North sub-branch, though Vulum has /r/. The labialisation from *kʷ has been reanalysed as the labialisation prosody in three groups and as a vowel in Giziga Marva. These are common sporadic processes. The change *k→h in Gidar is unestablished.

This well-attested root has a complex history. *w has been lost in many cases. Where it is present, it has been reanalysed as a vowel, or else as the labialisation prosody, which is a common sporadic process. This process has led to the loss of a syllable, and in several languages the first syllable of the root has been reduplicated to compensate for the lost material, which is also a common sporadic process. In the Kotoko groups, the *ɓ has transferred its glottal component to the *s, resulting in *ts or *sʼ. There is good evidence in support of the palatalisation prosody, and *i is found in those groups where it is expected.

This is one of two very common cooking verbs, with the other being the generic *d. There was a regular change *r→l in the North sub-branch and in Cuvok. This change should also have affected the Daba group, but this is not the case here. There was a regular change *s→z in Proto-West Tera. *w has been lost in many groups, and reanalysed as a vowel in some other groups, which is a common sporadic process.

This root is not well-attested in Central Chadic, but evidence from other branches indicates that this was probably the Proto-Chadic root. *w has been reanalysed as a vowel or the labialisation prosody, or has been lost. These are common sporadic processes. There was a regular change *r→l in the North sub-branch, though *r is present in Proto-Mandara, and /d/ is present in Bura.
