Common Mistakes in English - Have vs. Of in Conditional Forms

Have vs. Of in Conditional Forms

Of is used instead of have in conditional forms due to pronunciation (e.g. I would of visited New York if I had had the time.). "Of" is a preposition whereas "have" is an auxiliary verb used in conditional forms.
