Comment: In Tsakh. the stem is used in imperative (in pres. it has the shape -(h)aI, cf. aIl-ha 'to go', qI-ā 'to go away', aor. q-a=ɨ;s-āI 'to gather', aor. s-a=ɨ). In Rut. it is used both in the paradigm of the verb 'to go' and as a constative in the paradigm of the verbs 'to be, to become' ("is becoming...").
Comment: Cf. also Ud. Vart. b-ajinq: id. The PL reconstruction is highly hypothetical (since Ud. intervocal zero can reflect many PL consonants): it just means that the Ud. form can correspond to the other EC reflexes of *c̣VwnV-.
Comment: Cf. also Tab. Düb. uliš̌um, Ag. Bursh. ulus:um. 3d class in all class-distinguishing languages. Although the first vowel is hard to reconstruct (because of the reduction in the first syllable of a polysyllabic word), the general root structure and other phonemes are clear. In Tab. and Ag. there occurred a metathesis (ulus:um < *ʔum(u)s:ul < *ʔVms:ʷäla); in most languages the first weak syllable with a laryngeal was altogether lost.
Comment: The root is attested only in Archi, and has rather an exceptional conjugation there (baq̇Iá-s, pres. baq̇Iá-r, aor. boq̇Ió with a final stress), suggesting that b- is a former class prefix, and that the initial vowel of the root is reduced. The -n-conjugation is extremely hypothetical (suggested only by the external data).
Comment: Attested only in Archi (therefore the vocalic reconstruction for PL is hardly possible because of reduction in unstressed syllables), but having good external parallels.
Comment: Bud. ʕič is the MSU recording (Meilanova writes ħič which is probably wrong). A Shakhdagh isogloss (but with good external correspondences). The PL paradigm may be reconstructed as *ʔʷä(r)čʷ,*ʔʷi(r)čʷV-. The oblique base with -i- became dominating both in Kryz. and Bud., but the former direct base is preserved in Kryz. as a separate word ʕuč meaning 'colour' (PL *ʔʷä(r)čʷ obviously had meant both 'skin' and 'surface, colour' - as is clear from the external evidence).
Comment: Cf. also Lezg. Khl. on id. In several languages (Ag., Lezg., Rut.) serves as a base for the compound verb 'to hear'. Belongs to the 4th class in Rut. and Tsakh.; oblique base unknown.
Comment: Tab. -in is a rather productive suffix (cf. rak:-in 'door' etc.); without it cf. ur-ar (a former plural form) 'gate'. The root is attested only in Tab., but has rather probable Andian parallels.
