Proto-North Caucasian: *pVrVc_Ĕ
Meaning: wooden plough
Notes: A typical "culture word". Although similar words are widely spread in the Caucasus and nearby regions, only the Av.-And. and WC forms can be regarded as genuine. The Tsezian forms (Tsez. birus, Gunz. bǝrus, Bezht. boʔos, Khvarsh., Inkh. buruc; note that Av. Chad. burúš, because of its phonetic structure, is most probably a back-loan from Tsezian languages) are more or less recent loans from Av.-And. languages; the Av. word is also borrowed in Kum. purus. There is also a number of quite enigmatic forms: Bagv. Tlond. perec̣:, Ud. penec: 'plough' which are probably also borrowed, but the source is not clear. We should also mention Lezg. bazu "pole of the plough", obviously connected with Az. bazɨ id., but without a certain etymology (cf. the WC forms).
