Proto-West-Caucasian: *bawǝ ( ~ p:-)
Meaning: cattle-shed
Abkhaz: a-bóra,-bówra
Abaza: bora
Kabardian: bow
Comments: PAT *bawǝ-ra (with a common suffix -ra). Abkh. > Megr. aboura, abuura 'cattle-shed'; Kab. > Balk. bau id. See Shagirov 1, 101 (despite Klimov's opinion, quoted ibid., the Abkh. word - since it is clearly related to Kab. bow - has nothing to do with Slav. обор(а)).
