"Can" or "be able to" ?
Can and be able to
Be able to often has the same meaning as can.
- I am unable to/can’t understand his motive.
- He is able to/can support her.
Can is preferred in expression like can see, can hear etc. It is also used in the sense of ‘know how to?’
- I can knit. (More natural than I am able to knit.) (= I know how to knit.)
- I can see a ship. (More natural than I am able to see a ship.)
Be able to is preferred in cases, where can/could is not grammatically possible.
- I might be able to help you. (NOT I might can help you.)
- Someday scientists will be able to find a cure for cancer. (NOT Someday scientists will can find …)
