In English, the verbs "make" and "let" are followed by an object and the infinitive without "to":

They can't make you work late.
She made him do the exercise again.

She lets the students sing in class.
His parents let him paint his room black.

Be careful: in the passive, "make" is followed by the infinitive with "to":

They were made to do the exercise again.

"Have" can also be used in this pattern:

Please have your secretary call me as soon as possible.

(Please ask your secretary to call me…)

Other English verbs not followed by the infinitive + to

Modal verbs (can, will, would, etc) are followed by the infinitive without "to":

I can see him clearly.
They will leave early tomorrow.
If I were you, I would talk to her.

See / hear / watch someone followed by the infinitive without "to":

She saw the girl steal the money. (She saw all the action of stealing.)
I heard him tell her about the party." (I heard all about the party.)
I watched them do the exercise. (I watched them complete the exercise.)

But remember:
If you follow these verbs with the gerund form (ing), you only see part of the action.

She saw him talking to the teacher. (She didn't see the whole conversation.)
