We may be late for the meeting. There may not be very many people there. - See more at: https://learnenglish.britishcouncil.org/en/english-grammar/verbs/modal-verbs/may-might-may-have-and-might-have#sthash.jGDOu7Z9.dpuf We use might : • when we are not sure about something: I might see you tomorrow.

Second conditional https://learnenglish.britishcouncil.org/en/quick-grammar/conditionals-1 The second conditional is used to talk about ‘unreal’ or impossible things. If I won a lot of money I’d buy a big house in the country. Where would you live if you could live anywhere in the world? If you didn’t smoke so much you’d feel a lot better. The structure is usually if + past simple and would + infinitive . It’s not important which clause comes first. Look at the difference between the first and second conditionals. In January: If it snows tomorrow I’ll go skiing. It might snow tomorrow. In August: If it snowed tomorrow I’d go skiing. It almost certainly won’t snow tomorrow. NOTE: Although many conditional sentences use if + will/would, conditional sentences can also use other words instead of ‘if’ – e.g. ‘when’ ‘as soon as’ ‘in case’ Other modal verbs can be used instead of ‘will/would’ – e.g. ‘can/could’, ‘may’ ‘might’.
