ooc: If not stated in the character background or specific languages, you won't understand it but, if it seems likely that you've heard it in your travels, then you can recognize it. Also, even if you've never heard elvish before, you can most definitely tell that the melody and language is NOT goblin. As a Cleric of Knowledge, I'd agree that it seems likely that Eddicus would be able to say that it sound a lot like Elvish. Real world example: you hear some people talking in Polish, you don't know Polish but you can tell from the sound of the language that it is eastern European and definitely NOT German.
