Proto-West-Caucasian: *ča(n)čǝš́ǝ (~c,š́:)
Meaning: lizard
Abkhaz: ajnč̌ǝ́š
Abaza: arcǝš
Ubykh: ca(n)cǝ́š́
Comments: An expressive and very irregular stem (cf. also Abkh. Bz. aʕʷǝ́nč̣̌ǝš, ajǝnč̣̌ǝš); details of its morphological structure and history of transformations are not clear yet, but if the root is *ča(n)čǝ- (as suggested by the Ub. form), it probably has some parallels in EC languages.
