    3. MAY vs. MIGHT
      1. Always Use “May” When Asking For Permission “May I open the window?” This question is correct, but it sounds rather formal. Most English speakers would probably say “Can I open the window?” in everyday life.
      2. Always Use “Might” With “Not” I may not go to the wedding. --> don't use In this case, may not sounds like I don’t have permission to go. I might not go to the wedding. In this case, might not means maybe I will go, maybe I won’t go.
      3. Many native English speakers do not make a major distinction between may and might, and the two words are often used interchangeably – so don’t worry too much about it!
