Molon (accent on the last syllable) is a participle ("coming"), from the verb blosko meaning "to go," or "to come."
Labe (accent on the "e") is an imperative, "take!"
The ancient pronunciation of the "b" (beta) would have been like English "b," not "v" (as in the Modern Greek pronunciation of beta).
So literally, "coming, take!" but in better English "come and take them!"
Oh yes, I know. Just mean it got me to thinking about other languages. Probably could’ve worded that better. :o) Thank you for more information
