Common mistakes

I can to swim. → I can swim.
Never put to after can. Learners add it by analogy with want to, like to.
He cans play football. → He can play football.
can never takes -s, not even with he, she or it.
She can sings very well. → She can sing very well.
After can, the verb stays in its base form with no -s.

Memory tip

Remember one line: after can the verb is bare — no to, no -s, no -ing. Anything extra is a mistake.

Summary

  • can + base verb, the same for every subject.
  • Negative: can't. Question: Can at the front.
  • No to, and no -s on can or on the verb.
