Provisional and conditional essentially mean the same thing, IF something happens..., provided something happens... etc. For example: If I eat too much food, I will put on weight.......... Provided I revise for my exam, I will pass. Causative is the idea of making or causing someone to do something. In Japanese, the form can also mean to let or allow.
