Comment: Cf. also Lezg. daḳ-ar 'window; niche', Khl. ṭag (erg. ṭaḳa) 'window', Ag. Fit., Burk. ṭag-ar id. The Arch. word has a specific meaning: "collar for a calf" (*'a hole to put calf's head through'). Several forms reflect suffixed buildings: in *-ar (plural), in *-an (Arch.) and *-aj (Bud.). Labialisation of *t:ʷ- is suggested by the Kryz. and Bud. vowel -o-, having disappeared in other languages. Obl. base *ṭʷaḳa- is indicated by Lezg. daḳa-, Khl. ṭaḳa-. 4th class in Shakhdagh and Archi.
