There are three modal verbs used to show ability:

  • Can
  • Could
  • Be Able To


Examples:

Present
  • I can play the guitar.
  • She can speak German.

*
Can is always followed by a base verb.

Past
  • I could sing very well when I was young.
  • She could read when she was 2 years old.

Future
  • I will be able to drive a car in 2 years.
  • He will be able to buy a house next year.


"Able to" is used with many other verb tenses.  Take a look at
these examples:

  • I have been able to visit many countries in my life.
  • I used to be able to dance the Tango.
  • I will have been able to finish by tomorrow.


Negatives

Negatives are formed by using "not".

  • I can not play piano.
  • She can't play piano.

  • She could not finish her homework last night.
  • They couldn't finish their homework last night.

  • I will not be able to go to the party tonight.
  • Susan won't be able to go to the party tonight.


Questions

Questions are formed by changing the order of the words.

  • Can you drive a car?
  • Could he swim?
  • Will Doug be able to bring his boots?

Notice that "will be able to" is separated when used in a
question:

  • Will he be able to finish on time?
