Comments: Dumézil (1932, 120) relates Ub. -da in aj-da 'that, another' (cf. also -da- in mā-da-ḳ́a 'where') to Abkh. -da in á-la-da 'down', á-ʕʷa-da 'above' ( < PAT *-da, cf. Abaz. ʕʷa-da 'ascent, climbing'). While this may be true, we would also adduce the AT pronominal (agentive) prefixes of the 3d person singular and plural (*dǝ- > Abkh., Abaz. d(ǝ)-) and probably also the 3d person plural pronoun *da-ra 'they' (Abkh. da-rá, Abaz. da-ra).
In AK the stem is preserved in *a-dá 'there' (Ad., Kab. āda); cf. also Ad. tǝ-da 'where' and the PAK locative preverb *da- (Ad., Kab. da-). See Шагиров 1, 57.
