I don't mind manglings caused by naivete or by being a non-English speaker, but I do mind manglings caused by pretentiousness. The one that comes to mind most often is "comprise." Nobody seems to remember whether big things comprise little or little comprise big. (Do 50 states comprise the Union or does the Union comprise 50 states? I forget.) Anyway, most users don't even know there is a right way.I wish people would just quit using any form of "comprise."
BTW, I have heard perfectly cultivated English speakers say "hit" for "it." It depends what sounds preceded it. We probably all do it and have never thought about it.
