Q: I have heard the word “kefir” pronounced a number of ways. I would prefer to use a pronunciation that gives honor to its etymological origin. My research shows Caucasian languages as the possible source for the name. Any data on this topic that you would like to pass along?
A: “Kefir” is the English name for the fermented, yogurt-like drink made from cow’s milk, and its usual pronunciation in standard English dictionaries is keh-FEER.
Although etymologists say the term originated in the Caucasus, English speakers wouldn’t understand if you used a Caucasian pronunciation for the drink.
For example, the Georgian word for the drink, კეფირი, is kʼepiri in Latin script, while the Mingrelian word, ქიფური, is kipuri, according to the multilingual dictionary Glosbe.
In fact, English adopted the word from Russian, where the term for the drink, кефир, sounds much like the standard English pronunciation of “kefir.” The Russian term may ultimately come from a Turkic language spoken in the Caucasus.
The American Heritage Dictionary of the English Language (5th ed.) says the Russian term is derived “probably ultimately from Old Turkic köpür, (milk) froth, foam, from köpürmäk, to froth, foam.
Getting back to your question, we’d recommend using the standard English pronunciation, keh-FEER. If you were to walk into a grocery and ask for köpür, kʼepiri, or kipuri, the clerk wouldn’t know what you were talking about.
The Oxford English Dictionary, an etymological dictionary, defines “kefir” as an “effervescent liquor resembling koumiss, prepared from milk which has been fermented.” Koumiss is a drink made from fermented mare’s milk.
The earliest example of the term in the OED is from the July 3, 1884, issue of Nature: “Kephir has only been generally known even in Russia for about two years.”
The next citation is from the Nov. 3, 1894, issue of the Lancet: “Koumiss and kefyr are examples of sour fermented milk containing an excess of carbonic acid gas.” (After checking the original, we corrected an OED typo—“are examples,” not “and examples.”)
