Lit. Avar for an unclear reason has lost the -n-conjugation (still preserved in the Chad. dialect). Cf. also Cham. Gig. =ač̣n- 'to bend' and derivates: PA *=iḳVn- 'curved, bent' (Akhv. =ĩḳa-da, Cham. =ič̣anna, Gig. =ač̣a-m, Tind. =iḳ́ã-b, Kar. Tok. meḳ́a-b); Av. boḳón, Chad. buḳún, PA *bi(r)ḳun 'corner' (And. biḳun, Akhv. meḳu, Tlan. berḳen, Ratl. berḳʷen, Cham. beḳũ, Kar. buḳun, Tok. boḳun, God. biḳun). Av. boḳon > Cham. Gig. boḳon, Gunz. boḳon 'corner'; Av. suḳ- 'to bend' > Tind. suḳ-ij-, Kar. suḳ- id.
