What modal verbs can be used in Zero Conditionals (Present Real Conditionals)? For example, I have stumbled across such examples:
- If you want to go to university, you must study hard.
- If it can be dreamed, it can be done.
So, what modal verbs (from will, would, shall, should, can, could, may, might, must) and in which clauses can we use when forming this kind of conditionals in general?
