Some of the English words,which are similar to Serbian comes from Latin language.
"Day" and "dan" only look similar, but they aren't derived from the same Indo-European root: "day" comes from PIE *dʰegʷʰ- meaning "to burn" (it's cognate with Serbian "žèći"); while "dan" is from PIE *dyew- meaning "to be bright" (it's the origin of the words for "day" in many other IE languages too, but in Germanic it was replaced by the other word and in modern English it only survives, as far as I know, as the -t in "Lent").
"Mill" and "mlin" are both ultimately borrowed from the same Latin word ("molinum").
