Grammar - Conditional
In grammar, conditional can mean two things. Firstly, the conditional form (mood) of a verb, which is made from would (also should with ‘I’ and ‘we’) plus the infinitive without ‘to’:
He would see.
Should we stay or go?
Secondly, conditional is used to refer to a clause or sentence expressing the fact that something must happen before something else can happen, for example:
If I had more money, I’d buy a bigger house.
Should you change your mind, we’d be happy to help.
