Comment: Labialisation in Lezg. is clearly secondary (all other languages point to *χ). The original meaning was probably 'to lie; to throw, fall', cf. Ud. b-arχi 'horizontal' ( < *'lying') (perhaps also, with prefixation and Ablaut, Rut. qa-ruχa-s 'to throw'). A local derivate from this root is Tab. aχin (Düb. aχin) 'bed', Ag. Bursh., Fit. aχun id., Rich., Burk. aχun 'mattress'.
