· May have and might have are used when we wish to state that something has possibly happened now or sometime ago.
The bride groom’s party might have arrived by now. ( Perhaps they have arrived.)
They may have given the advance for the flat.( Perhaps they gave the advance, long back).
· Must have is used to express a probability in the past.
Geetha must have taken the umbrella.
The thief must have escaped through that window.
Now, go through the following sentences:
· They could have easily solved the problem. (It was possible for them but they did not do so).
· They will have finished writing the examination by now.
· I thought you would have informed your parents about this.
· You should have been more careful.( You were not and so you are in trouble now.)
· Nilesh may have repaid the loans.( Perhaps he repaid them long back).
· Meena is not at home now. She might have taken her child to the music class. ( Perhaps she has)
· Don’t worry about your cell phone. Your mother must have kept it safe.(It is quite probable that she has)
*We will discuss the difference between ‘possible’ and ‘probable’ in the next post.
