Hi, Do all of the above sound right and mean about the same to you? By the way, is it still all right to omit all of the prepostions, that is, over, on, and about? Thanks.

	Mr Wordy  +  543334 Sat, 19 Jul 08 02:26 AM I would omit the preposition altogether. "over" and "about" seem acceptable to me, but "on" sounds odd. This appears to be the exact opposite of what Google's hit counts are telling me, so that just shows how much I know. It could be that "debating on" is more a US usage I guess. (I think I would also say "beneficial to", but I don't think "for" is wrong.) Mr Wordy Joined on Tue, May 27 2008 Senior Member 2,359 Native British English speaker Prepositions
