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
We use to + infinitive after certain verbs: 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.
We also use to + infinitive after certain verbs and their object: ask, tell, want, need. He asked me to go there with him.
She told me to help her.
