Hey H Lewis, I shall provide you with information regarding the difference amongst these three verbs: * These words are used to talk about ability, awareness, and possibility. They are also used to say that someone has permission to do something. ''Can and ''could'' are called modals. Both ''can'' and ''could'' are followed by an infinitive without to. E.g.: ''I envy people who can sing.'' E.g.: ''I could work for twelve hours a day.'' E.g.: ''Do not eat this - it could be poisoned!'' E.g.: ''I can go for a walk now.'' E.g.: ''You should not tell her about your secret - she could make it public! ''Might'' and ''may'' can be used in a similar way. E.g.: ''It might be a trap.'' E.g.: ''Her career may be ruined.'' E.g.: ''I might finish this work when I get home.'' E.g.: ''I may not be able to help you.'' Here is a hint for you: 'Might' is the past tense form of 'may' and it is used to talk about a future event that is a remote possibility. CONSIDER the following sentence: ''This camera is a bit cheaper than the other one, although it might not be as good, of course''. Here, the usage of ''might not' is justified by the fact that there is a remote possibility that the camera concerned could not be as good as the other one. Now, if you are certain (almost a hundred percent sure) that the camera is not as good as the other one, then you could use 'can' instead of 'might'. Examples: 1) It may not rain today = (you are 50% sure that it is not possible that it will rain today) 2) I might do my homework = (I am 50% sure that I will do my homework) 3) That camera might not be as good as the other one (that camera is not likely to be as good as the other one) 4) I won't buy that camera - it can't be as good as the other one = (I am stating that the camera is not that good - in this case, I am 70% sure that the camera is not worth buying) **** NOTICE: The usage of 'Can' reveals a stronger possibility as opposed to that of 'might / may'. Hope that helps!!!

"Can" refers to ones ability to do something. Such as, I can speak English, she can bake cookies, or he can drive a car. Along a similar line "can" can also refer to ones ability in terms of permission or availability. Such as, "My mom says I can go to the movies with you" or "I cannot come visit you this weekend because I am busy". "Can" is also used when talking about doing something for someone else, particularly in the form of a question. An example would be, "can you please walk the dog (for me)?". In this case the "for me" can be said or it can be dropped and is therefore implied. "May" refers to ones ability to do something but only in terms of gaining/giving permission. Examples would be, "may I please go to the movies on Friday?" or "Yes, you may" or "No, you may not". In cases where you use "may", you are actively seeking permission to do something or you are giving/taking away permission. Often in spoken English "may" is replaced with "can" even though that is not grammatically correct. Two main examples of this would be, "Can I go to the movies on Friday?"(incorrect) vs. "May I go to the movies on Friday?"(correct) and "Can I please be excused from the table?"(incorrect) vs. "May I please be excused from the table?"(correct). Finally, "might" is used when the speaker is unsure of various different situations. Some common uses of "might" would be, "I might to the movies on Friday but I also might stay home instead", "She might get the job or it might go to him instead" or "Be careful when you talk to John. He had a really bad day so he might be mad". I hope this has been helpful:)
