Infinitives with to
The marker to is normally used before infinitives. Note that this to is not a preposition; after the preposition to we use -ing forms.
The to-infinitive has many functions.
Infinitive as subject
An infinitive can be the subject of a sentence. This was fairly common in older English.
- To err is human, to forgive divine.
- To find fault with others is easy.
In modern English, this is unusual. We more often use it as a 'preparatory subject', and put the infinitive clause later.
- It is human to err.
- It is easy to find fault with others.
Infinitive as object
Many verbs can be followed by an infinitive clause in the place of the direct object.
- She wants some exercise. (noun object)
- She wants to dance. (infinitive object)
- I don't want to go to bed.
Infinitive clause as complement
An infinitive clause can be used after be as a subject complement.
- The best thing to do now is to vanish.
- You are to sit in that corner and keep quite.
- The main thing is to stay calm.
To-infinitives can be used as the object or complement of a verb, adjective or noun.
- You have the right to remain silent.
- She was anxious to contact her husband.
- That was a sight to see.
- Automation has come to stay.
- It is time to go.
