Comments: PTsKh *ʕö̃ƛ̣ (NB: Bokarev cites Inkh. eƛ̣ 'handle' - which must be the same word as the MSU recording ẽƛ̣ 'hammer-handle'); PGB *ʔãƛ̣ (the Gunz. form is not quite regular: PGB *ʔɔ̃ƛ̣ and Gunz. ɔ̃ƛ̣ would be regularly expected - one wonders if the Gunz. form is not a borrowing from Bezht., cf. Bezht. Khosh. aƛ̣ id.).
Comments: PTsKh *ʕöƛ̣; PGB *ʔãƛ̣ (cf. also Bezht. Tlad. ãƛ̣, Gunz. Nakh. ãƛ̣). The root is a full homonym of PTs *ʕɔ̃ƛ̣ B 'handle' (q.v.) - but this is probably due to a secondary merger, because external parallels for both roots are different.
Comments: PTsKh *ʕomoq̇e. The Bezht. form can be related here if it goes back to PGB *ʔɔ̃q̇u ( < *ʔɔm-q̇u).
The component *-q̇V in the PTs form is not clear etymologically. There also could have existed a PTs variant *ʕɨmVrV ( = PL *ʡimal), reflected (with a productive suffix *-ṭu) in PGB *ʔɨrmV-ṭu (Bezht. irmaṭo, Gunz. ɨrmǝṭu) 'ass'.
Comments: PTsKh *-aƛ-, PGB *χ-aƛ-. The root is used with expressive preverbs (cf. also Tsez. ħ-aƛ- 'to stick into'). Tsez. ƛaħʷ- 'to tear, burst' may be a parallel for the Proto-Av.-And. derivate *ƛ̣:ʷa-h- 'to burst, to shoot' (see above).
Comments: An irregular correspondence (ṭ/t) is explained by the grammatical nature of the morph. Cf. also Gunz. -iṭ- suffix of negative past gerund (showing that the vowel here does not belong to the negative affix itself).
Meaning:1 3d sing. and 1t plur. class marker 2 3d and 6th sing., 1t/2d (anim.) plur. and 6th plur. class marker 3 3d sing. and 1-2d plur. class marker 4 4th sing., 1t/2d (anim.) plur. and 6th plur. class marker
Comments: The original meaning was 'soft' (cf. the external evidence). Since in Caucasian languages the meanings 'soft' and 'warm' are often interrelated (cf., e.g., *tVntV ), we may think that another old derivate of the same root is PTsKh *bobo-RV 'hot' (Tsez. boboru, Gin. bobore, Inkh. bobolu), which otherwise has no etymology.
