[T Minus Four]

OK, here's another one that makes me crazy, and lots of a lot of many educated folks do it - using an apostrophe in the possesive form of "it".

it is = it's
belonging to it = its

I believe it's the only possesive form that doesn't use an apostophe.

No pronouns have apostrophes.

Contractions always have apostrophes at the point at which the extra letters were squeezed out.

It is = it's (the "i" was squeezed out by the contraction, and in its place, you must put an apostrophe.

I've = I have (The "ha" was squeezed out by the contraction [like muscles squeeze when they contract]...in their collective place, one puts the apostrophe.)
