Which is correct
"Could have" - always. "Could of" is an error.
Why people write "could of"
In spoken English, "could have" contracts to "could've" (sounds like "could-uv"). When people write what they hear, they write "could of" - because "of" sounds like "uv."
This is called an eggcorn - a word or phrase misheard and reinterpreted as something that sounds similar.
The same mistake happens with
- "Should of" β should have (should've)
- "Would of" β would have (would've)
- "Must of" β must have (must've)
How to spot the error
"Could" is a modal verb. Modal verbs are always followed by a base verb ("have"), never a preposition ("of"). Ask: does "of have" make sense? No. "Have" always follows.
In formal writing
Always write "could have." "Could of" is considered a grammatical error.
