samovar (n.)youdaoicibaDictYouDict[samovar 词源字典]
1830, from Russian samovar, literally "self-boiler," from sam "self" (see same) + varit "to boil" (from Old Church Slavonic variti "to cook," from PIE root *wer- "to burn"); but this is perhaps folk-etymology if the word is from Tatar sanabar "tea-urn."[samovar etymology, samovar origin, 英语词源]
