May or might?
May and might are both ways of expressing that the truth of something is unknown at the time of writing or speaking. Is there a difference between the way in which they should be used?
Some people insist that you should distinguish between may (present tense) and might (past tense), when you want to express this sense of possibility. For example:
I may go home early if I’m tired. (present tense)
He might have visited Italy before settling in Nuremberg. (past tense)
In practice, this distinction is rarely made today and the two words are generally interchangeable:
I might go home early if I’m tired.
He may have visited Italy before settling in Nuremberg.
