    Grammar Point could / should / would havecould / should / would haveA common mistake is to write ‘could of’ instead of could have or could've
    • I could of told you that.
    • I could've told you that.
    The reason for the mistake is that the pronunciation of ’ve is the same as that of of when it is not stressed. This is a common error but it is definitely considered wrong in standard English.
