Comment: Cf. also Tsakh. Gelm. dedäj 'grandfather' ( < *t:at:a-j), Kryz. Al. dadaj 'mother'. In Arch. there occurred an irregular change *dida > dija (cf. *buba > buwa 'mother). There are several forms presupposing a partially reduplicated protoform *ʔadaj: Bud. ada 'father', Tab. edej 'grandfather', Kryz. däj 'mother'. Ruite irregular and contracted reflexes of the same "children's word" may be observed in Tab. daši 'father' (cf. Darg. *t:ut:e-š) and Tsakh. da-ḱ id. Within Lezghian languages forms meaning 'father' ('daddy') and 'mother' ('mummy') are usually in complementary distribution, so it is hard to separate them from each other.
