The infinitive

 

 

 

 

 

WHAT IS AN "INFINITIVE"?

The infinitive is the base form of the verb. Sometimes the infinitive is used with to, and sometimes without to.

THE "TO" INFINITIVE

Remember that you use the to infinitive:

1

To express purpose.

Some examples:

I'm leaving next week to start work on the Mediterranean project.
He went to the Technology Centre to buy a computer.

 

2

To report orders, requests and advice.

Some examples:

He told me to look in the instructions manual.
He advised me to buy the more expensive model.

Some reporting verbs which can be followed by a to infinitive are: advise, ask, command, encourage, forbid, invite, order, persuade, tell, and warn.

 

3

After certain verbs.

Some examples:

I intend to begin in Spain and Morocco.
He's planning to visit all the Mediterranean countries.

Some verbs which can be followed by a to infinitive are: afford, agree, appear, arrange, attempt, decide, expect, forget, hope, intend, learn, manage, offer, plan, promise, refuse, seem, and want.

 

4

After certain verb + object patterns.

Some examples:

I'd like someone to phone me back immediately.
He wanted a technician to repair the fault.

Some verbs which can be followed by this pattern are: allow, enable, expect, force, get, help, like, permit, prefer, remind, teach, and want.

 

5

After certain adjectives.

Some examples:

It should also be fairly simple to operate.
It's unlikely to be cheap.

Some adjectives which are followed by a to infinitive are: difficult, easy, important, impossible, likely, pleased, possible, simple, unlikely, unusual, and usual.

 

THE INFINITIVE WITHOUT "TO"

Remember that an infinitive without to is used:

1

After modal verbs.

Some examples:

This camera must be fairly simple to operate.
It should be fairly simple to operate. It has just three buttons!!

 

2

After let, make, would rather (= prefer) and had better (= should).

Some examples:

Could you let me have your ideas as soon as possible?
I can't make it work.
He'd rather have a new computer than a refund.
He'd better write a letter of complaint.

 

TIPS TO REMEMBER

You may find the following tips about infinitives very useful:

A

1) Passive infinitive    to be + past participle

I don't want to be told it's my fault.

2) Perfect infinitive    to have + past participle

They seem to have forgotten their responsibilities to customers.

 

B

Although the infinitive without to is used after most modal verbs, there are some exceptions: have to (= must), ought to, used to:

Some examples:

I have to work overtime tonight.
You ought to take more exercise.
She used to drive to work but now she goes by bus.
