Comments: PAT *ć̣ǝ-ćǝ 'new' - cf. Abkh. Bz. a-ć̣ǝ́ć. Historically this is probably a reduplication (with dissimilative loss of glottalisation in the second part). In the Abzh. dialect and in Abaz. the word was transformed to č̣ǝc under influence of another root, *č̣a q.v. The pure root *ć̣ǝ is preserved in Abkh. a-j-c̣-rá (Bz. a-j-ć̣-rá) 'to be younger, smaller', a-j-c̣-bá (Bz. a-j-ć̣-bá, Abaz. ajc̣ba) 'junior'.
The AK languages preserve this root only within the compound *c̣ǝ-ḳʷǝ́ 'small, young, youngster' (c̣ǝ- regularly < *ć̣ǝ-; the precise meaning of the second component is not quite clear yet).
