These are two usages of the preposition for for which I couldn't find a suitable definition. Maybe I should ask two separate questions, but since they are about two senses of the same word, I figured asking them in one post might be acceptable.
So, what does for mean in the sentences below? Are these standard usages of for?
- I finally saw him for what he was and broke up with him.
- I know I have flaws, but why don't you accept me for what I am?
The only way I could make sense of them was by replacing "for what" with "as" (saw him as he (really) was -- accept me as I (actually) am). But what about "for" alone?
- It's too late to melt all this fat now. I've got a sagging bag for a belly, and I always will.
- After I told her everything I realized I had a cheat for a friend.
My guess is, here "for" means "instead of" or "as". Am I right? Is this sense always used for complaining?
