Topic: Infinitive Clauses
An infinitive clause is part of a sentence with a verb in the infinitive form. The infinitive form is sometimes without ‘to’, and we form negative infinitives with ‘not to’ + verb.
Section A: verb + (infinitive / verb) + object
After verbs such as advise, allow, ask, expect, force, get, hate, like, love, invite, need, pay, persuade, tell, want
Jake loves to visit museums.
I don’t want you to read my emails.
I advised him not to come to the party.
Section B: Infinitive clauses that function as the subject of a sentence
These sentences are usually formal or old-fashioned English
To make mistakes is human.
To say that he was here is simply not true
In information or neutral English, we say
It’s human to make mistakes.
It’s simply not true to say that he was here
Section C: Noun + infinitive
Do you have a pen to write with?
I’d like something to drink.
Section D: Explaining ‘why’ we do something
He opened the box to see what was inside.
He got home early to cook dinner.
They went to the station to buy a ticket.
Section E: verb + object + infinitive without ‘to’
After verbs such as help, let, make, watch, see, hear, have
Can you help me make dinner?
I saw him leave the house.
I won’t let you stay.
Section F: ‘for’ + (noun / pronoun) + infintive
If an infinitive has its own subject, we something use this structure
It’s important for you to arrive early. (= It’s important that you arrive early)
It’s necessary for him to stop.
It’s bad for you to eat too much chocolate.
It’s a good idea for him to arrive early.
