Randi's Spelling Post, found on another board

It’s = it is. As in "It’s a crying shame that Firefly was cancelled." Also used for it has, as in "It’s rained every day this week."

IT SURE IS!

Anyway, I've always been kind of the "grammar police" but I have atrocious spelling. I'm also prone to typos.

Thanks for the apostrophe site, one of my biggest pet peeves is unnecessary use of apostrophes.

I'd like to add this site:

It is VERY good in outlining the ONE SIMPLE RULE to apostrophe use. It also explains why I read "boy's" as "boys-es"

Come to think of it, that's probably why I'm so annoyed by overuse of apostrophes!
