In a song I know, there's the line:
Who's more of a beast?
The rest of the lyrics around this makes it clear that it should mean something like "Who is more like a beast?" or "Who as more characteristics of a beast?".
So the 's, does it refer to is or has in this context?
How would one say this?
Who is more of a beast? or Who has more of a beast?
I would think "is", but in German one would rather use the direct translation of "have"...
