We use might: • when we are not sure about something: I might see you tomorrow. It looks nice, but it might be very expensive. It’s quite bright. It might not rain today. • As the past tense of may for requests: He asked if he might borrow the car. They wanted to know if they might come later. • For very polite requests: Might I ask you a question? Might we just interrupt for a moment? We use may have and might have to show that something has possibly happened now or happened at some time in the past: It’s ten o’clock. They might have arrived now.[= Perhaps they have arrived] They may have arrived hours ago. [= Perhaps they arrived hours ago.]
