Grammar 101: Could of, Would of, Should ofAugust 18th, 2009 by Michael Kwan
Do you know the difference between should of and should have? Do you know which one is correct?
Well, I’ll make it easy for you: Should of is wrong. It is always should have and the same applies to similar constructions like could have and would have. They are not could of and would of. The of/have confusion is much like the confusion that some people have with then and than. It’s because these pairs of words sound similar when spoken; it can become challenging to differentiate between them when writing them.
Try saying should’ve out loud. That can sound a lot like should of, but that would be wrong. It can either be should have or should’ve, but never should of. This is an easier distinction than affect/effect, since there is only one right answer.
Correct: “I should have gone when I had the chance.”
Incorrect: “I should of gone when I had the chance.”
Correct: “He would have ordered a drink, but he was sick.”
Incorrect: “He would of ordered a drink, but he was sick.”
