Noone is bad enough, I'll warrant (see thread below), but the offense against not only Oxford, but against Webster, that eclipses them all is the use of your when you mean you're. This one is enough to drive both the Devil and Daniel Webster straight up the wall; and it's everywhere you look. How did some of you gentle folk ever get out of eighth grade?
Your going to regret this (likely I will).
Your traveling over the speed limit.
Why tell anyone what your doing?
Why use your when you mean you're? As in ALL the examples above? Anytime you think about using "your" just say the sentence out loud substituting "you are" and see what you decide to do.
But I've brought this up before only to be ignored.
Maybe I would be lots better off letting the Brits have it for making words way, way too long, e.g. draught for draft, and such as that. And if bough rhymes with cow, then why doesn't cough rhyme with cow? And such as that? It's enough to push the more sensitive over the edge. And we may as well leave scissors and muscle completely out of this discussion.
