Anonymous  +  696809 Sun, 12 Apr 09 07:47 AM Hi, What's the difference between may have and might have? Are both these two interchangeably used as a third past conditional sentence, or there is any specifice difference between these two? Thanks in advance.

As reported speech, 'might' is past of 'may': 'I may go shopping.' John said that he might go shopping. As 3rd conditional, only 'might' (as the past form of 'may') works: If I had been in Tokyo yesterday, I might have gone shopping. .
