‘Would Of’ or ‘Would Have’?

When people say or write would of, should of, could of or might of, they really mean would have, should have, could have or might have. For example:
✅ I would have been an only child if it weren’t for IVF.
❌ I would of been an only child if it weren’t for IVF.
✅ You should have studied harder for the exam.
❌ You should of studied harder for the exam. (Hope it wasn’t an English exam!)
The conditional perfect, or the type 3 conditional
The conditional perfect is a verb tense that refers to a hypothetical or alternative event or situation in the past. Essentially, it represents a missed opportunity, often hinging on something else happening. Could have, should have and would have are the modal verbs used for the conditional perfect, expressing past occurrences that didn’t happen. For example:
✅ I would have given it to her if she had asked.
✅ I could have run the race, but I decided to wait until my leg was better.
✅ I should have told her; now she’ll never know how I feel.
Why do people mistake would of for would have?
When you say would of instead of would have, you’re substituting the preposition of for the auxiliary verb have, which is grammatically incorrect.
