dirtydog said:Something else you see on these forums and lots of other places are things like:
"on it's own"
which makes as much sense as writing their's, your's or her's.
Most people seem to think it is correct though, but they are of course wrong.
They are not far from the correct usage though, so it's not exactly a million miles away.
It's can be used to abbreviate it is. (It's cold in here.)
