8 Mistakes you should never make...

Modal verbs are auxiliary verbs (also called helping verbs).

After an auxiliary modal verb, the root form of the main verb is generally used, e.g., I can play the piano. 

An infinitive verb should not appear after a modal verb, e.g., I can to play the piano.

Also, remember that there is no infinitive "to can."  You have to say "to be able to."

I want to be able to play the piano.
