Question

Which corrects the incorrect pronoun or contraction in the sentence?

Why can't you put my coat in you're locker?

A.
cant'

B.
cannot

C.
you'er

D.
your

A?

Answer 1

Well A puts the apostrophe in the wrong spot.
Apostrophes never go outside the word unless it is showing possession of someone whose name ends with an s. For example:
It is James' pencil.
The kid's name is James, so we put an apostrophe after the s.
In all other cases, apostrophes always go between something, like so:
"It is Mary's pencil."

Answer 2

So, let's look at the different versions of "you."

You're: A contraction for "You are."
Your: Your possession: "It is your car."

Answer 3

So read your sentence aloud but instead of reading it with "you're," read it as "you are."
Does it make sense?
Why can't you put my coat in you are locker?
