samovar (n.)

1830, from Russian samovar, literally "self-boiler," from sam "self" (from PIE root *sem- (1) "one; as one, together with") + 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."
