Brilliant, I've thoroughly enjoyed this too. Of course, I take it all in the spirit in which it was intended.
A few of my own; when someone says they've 'learned' someone something instead of teaching them, or 'lent' an item when they borrowed.
Or when they 'won' someone else in a race instead of beat them.
And what about 'pacifically' instead of specifically.
And my point of the moment is 'less' instead of 'fewer'. Lynn Truss says she refuses to patronise supermarkets which have tills for 'ten items or less' when it should be fewer. [The rule is it's 'fewer' when there's more than one item (such as 'fewer people') but 'less' when it's a smaller amount of a single item ('less of a crowd'). It took me a little while to get the hang of, but once I did, it stick's out like a sore thumb.]
I'm terrified now about getting this post accurate, and realise that those who live in glass houses shouldn't throw stones, but just can't resist it. I would never correct someone I didn't know well, and make sure they always know the spirit I offer it in.
And I LOVE prostate for prostrate, but sometimes have to correct myself before it slips out .
