кефир

Noun

 * 1) kefir

Etymology
Borrowed into Russian from a language of the Caucausus; compare 🇨🇬, 🇨🇬, 🇨🇬. The ultimate origin is. The fact the word has an f instead of a p indicates possible transmission to Russian through 🇨🇬, which would have served as a lingua franca in the Muslim parts of the Caucasus. Relation with a potential Kipchak substrate *köp-ür- is unknown; if that is the case, cognate with 🇨🇬 ("to foam"), 🇨🇬 ("to swell") and 🇨🇬 ("foam").

Noun

 * 1) kefir (a yogurt-like beverage made from fermented cows' milk)
