The verb is attested only in Bezht. Much wider spread are the nominal derivates: 1. PTs *rɔLV A: Tsez. reʎa-j, Gin. reʎa, Khvarsh. loʎe, Inkh. lolo (PTsKh *RoLV), Bezht. Tlad. ral, Gunz. rɔl 'threshing' (PGB *rɔl).
2. PTs *mɨLǝ A: Tsez. meʎi, Gin. meʎe, Khvarsh. meʎa, Inkh. mulo-lo (PTsKh *mɨLǝ), Bezht. Tlad., Khosh. mur, Gunz. mɨlu (PGB *mɨl(u)) 'threshing board'. Bezht. has here -r- instead of -l- probably because of dissimilation which occurred in the oblique base (cf. Tlad. mur-li-, Khosh. mur-li-) and later was extended to the direct base.
