Comments: PAT *(bǝ)la (in Abkh. dialect variations: á-bla and á-la). Certain problems are connected with the PAK form *na : it is certainly related to PAT and Ub. forms (even several identical compounds with the component 'eye' may be observed in AK and other languages), but reasons for nasalisation are not clear (regularly *da would be expected; note that in this case the root would be homonymous with *da < *ĺA 'ear' q.v.).
