Notes: Reconstructed for the PEC level. The root is very close phonetically to *ʡwĭlʡĭ 'eye', and in Lak. and Avar the two words are indeed homonymous. However, reflexes differ in PD and Bezht., thus the homonymy is most probably accidental.
It is interesting to note an analogous homonymy in Georgian (twali means both "eye" and "wheel") - this could be due to an influence of EC languages, where the two words coincided by chance.
