Comments: Cf. also Av. s:únṭ-ize 'to smell'. Historically -ṭ may be an expressive suffix; cf. also s:úns:u-di-ze (a reduplicated form) 'to puff', s:ún-χ:i-ze 'to blow one's nose'. Cf. also Kar., God. s:unḳ- 'to smell'. Av. > Lak. s:unṭ 'snuff', s:unṭ učin 'to smell' (if these forms were not borrowed, s- would be expected in Lak.), probably also > Arch. s:unṭ-bos 'to smell', Darg. Chir. s:unṭ-ī id.
