Verb and to infinitive

When we have two verbs together in a sentence, the form of the second verb is influenced by the first verb.

This table shows which verbs require the second verb to take the to + infinitive (sometimes called the full infinitive) form.

Verb + to + infinitive

To + infinitive is used after such verbs as: agree, arrange, decide, offer, seem, plan, want, need, promise, hope, refuse, start, stop.

I have decided to lend him the car.
He offered to help me.
He promised not to say anything.

To + infinitive is used after certain verbs which can be followed by an object, such as: ask, tell, want, need.

He asked me to go there with him.
She told me to help her.
