Proto-Turkic: *saja-
Meaning: to be rare, thinned out
Russian meaning: быть редким, прореженным
Tatar: sajɨq- (dial.) 'to become rare', sajaq 'rare'
Khakassian: saja-
Oyrat: saja-
Chuvash: sojak (dial.) 'bastard'
Bashkir: hajaq 'rare' (dial.)
Comments: VEWT 395, TMN 3, 306, ЭСТЯ 7. The root is not widely attested, but its likely derivative is *saja-k 'young male horses separated from the herd; lonely man, wanderer', spread much wider (see ЭСТЯ 7). Chuv. sojak definitely reflects the same form and is not borrowed from Mar. sajak, but rather vice versa, despite Федотов 2, 53.
