Comments:Cf. also Evk. sirahun 'whey' (possibly reflecting an unattested Mong. *sira-sun). MMong. širxe 'vinegar' (HY) is most probably borrowed < Turk., see Щербак 1997, 145. The vowel in Turkic is not quite clear (*sürke or *sörke would be expected); cf. also Karakh. (MK) sorquč (perhaps sarqɨč or sɨrquč - vocalization is uncertain) 'a k. of spicy plant (chicory?)', see EDT 848.
