Place the apostrophe in the spot where a letter(s) has been removed to make a contraction.
It is = it’s, there is = there’s, cannot = can’t, was not = wasn’t
Tip: The number one mistake writers make is to use the word it’s when they should write its or your when they should write you’re. Read your sentence adding the word that a contraction has deleted to determine if it makes sense.
