I am afraid that when I hear it (if I hear it) I may introduce palm to forehead aggressively (an action some of you might in fact encourage me to do):
Is there one word to express "not belong"? As in:
That book does not belong on that shelf. It belongs on this one with the other compilations of Manitoban poetry.
I really feel I don't belong here. I mean, everyone is dressed so nicely and speaks so properly, while I in my oversized plaid shirt mumble nonsensically.
Thus, I mean an antonym to belong in the sense of "used to say that someone or something should be in a particular place or situation" (from M-W).
