Proto-North Caucasian: *jājV
Meaning: mother, grandmother
Proto-Avaro-Andian: *jaja Notes: A nursery word (like many EC kinship terms). As far as the Andian form is concerned, regularity of correspondences is violated (*j should not be preserved in PA), which is not surprising in a word like this. The PTs - PL parallelism, however, makes the PEC reconstruction probable.
