Comments: VEWT 95, TMN 3, 80-81, Лексика 373. Kypch. > Chuv. čakma 'fire steel', whence > Mari, Udm. (Федотов 2, 387). The verb is usually regarded as one of the meanings of *čak- 'hit, strike', but the semantics 'strike fire' is attested quite early and allows to use the Turkic material in the Altaic comparison.
