Recently I came across this great site called MAL (Master Any Language) with flash cards, games and lists of words in Serbian and English. It is obviously in an early phase, and there are a few mistakes, which really made me laugh. For instance, for the word 'train' we use 'voz', never 'komora' or for 'hot' we say 'vruć' not 'gorući', and for the part of the body called 'calf', we use 'list', never 'batak' (this is used for poultry or for women's legs in sleng, usu. in Pl 'koji bataci', but this is not suitable translation for a flash card at an official language learning site) :o) Nevertheless, I am sure these mistakes will be corrected.
"noga" or "list" not "batak"!
