I have given up on the "your" thing instead of "you're" for you are. Fully over half of the people here (and this being a fairly intelligent bunch) can't figure that one out. I suspect about half the teachers in the US don't know either because obviously they didn't correct many for all 12 to 16 years of education.

As a result, I expect "your" to become an acceptable use for the contraction in the dictionary sooner rather than later.

Did someone bring up there, their and they're? Well, that's just too difficult for way too many. If you don't have that down by now, you'll never get it right.

Here's an obscure one: complimentary/complementary.
