    "Can" and "able to" are the same in the present tense:
  • Can you take on this project?

    Yes, I can take on this project.
  • Are you able to take on this project?

    Yes, I'm able to take on this project.

    The negative forms are can't and not able to - or unable to:
  • Sorry, I can't take on this project.
  • Unfortunately, I'm not able to take on this project
  • Unfortunately, I'm unable to take on this project.

    Can/can't are more informal and more common in everyday speaking. Able to and not able to / unable to are a little more formal.

    In the past, we use could/couldn't or was/wasn't able to (or was unable to):

    In general, both are used in the negative form:
  • I wasn't able to finish all my homework yesterday.
  • I was unable to finish all my homework yesterday.
  • I couldn't finish all my homework yesterday.

    But in the positive form, "was able to" is a little more common than "could":
  • I was able to leave work a little early yesterday.

    In the future, there is only will/won't be able to. Don't say "will can" or "won't can" - it's a common error in English!
  • I have some free time tomorrow, so I'll be able to work on this project.
  • Sorry, I won't be able to go fishing tomorrow. I have another commitment.

    When you are making a polite request for someone to do something, use "could" (more formal) or "can" (more informal):
  • Could you please bring me a glass of water?
  • Can you please bring me a glass of water?

    When asking about someone's abilities, you can use either CAN or ABLE TO:
  • Can you read Japanese?
  • Are you able to read Japanese?

    Can is probably more common in spoken English, simply because it's shorter.
