What's the semantic difference between muri/oi kai\ a)perei/sioi?
I can't quite tell, but I think the former simply means "uncountable" for a noun while the latter would be used for some intrinsic aspect of something, like "his limitless rage".
Or, do they both simply mean the exact same thing? When would I use one over the other?
Also, is there a word: perei/sioj? I get the impression that there is, but it isn't in any ...
