It is not acceptable in a post beginning "Judging by the standards of written language"; it is an error of written language, whatever you may say, Mr H.

Thread drift is scarcely unprecedented on this forum, is it? And it's you who have 'accomplished' it, not we, by persisting in arguing with Eliza and me over a matter in which we knew better. You still haven't furnished a respectable example of what you claim, inaccurately, to be a correct and accepted usage.
