Comment: Cf. also Lezg. Kur. gʷeṭi 'narrow'. Initial *gʷ- may be also reconstructed on basis of Lezg. data (but in Lezg. gʷ- may be < *k:ʷ- before the following glottalized stop). In Shakhdagh there occurred an assimilation (-ṭ- > -d-), usual in roots of this type.
Vocalic quality is not clear (because of reductions in the first syllable); pharyngealization is probable because of front-vocalic reflexes in Lezg. and Ag.
