Proto-North Caucasian: *=iƛ̣ɨ̆lV
Meaning: thin
Notes: A common NC root with regular correspondences. Class prefixation is retained in Andian languages and Darg.; labialisation in PWC is probably also a vestige of class prefixation (*ƛ̣́ʷa < *w-iƛ̣ilV with vocalic assimilation). However, a prefixless variant *ƛ̣ɨ̆lV (reflected in Av., Lak. and PL) may also have existed already in PNC or PEC.
The Lak. form has a pharyngealized vowel, which may reflect some lost laryngeal; but since other languages do not reflect it (see above about the secondary nature of pharyngealization in Tsakh.), it is probably new (expressive).
