In connection with a discussion in another sub-forum I'd like to enquire about the etymology of samovar, which I think is Russian. This word is also used in Iran, Turkey and other places. This source http://www.etymonline.com/index.php?term=samovar gives the Russian etymology but suggest this is folk etymology and this word may have originated from Tatar language. What do Russian language sources say about it? Thank you very much.
