English Review of Gerunds and Infinitives

When one verb follows another, the second verb is either an infinitive (decide to apply) or a gerund (enjoy cooking). Which one you use depends on the first verb, so learn them in pairs.

This unit offers a review of gerunds (verbs ending in “ing”) and infinitives (e.g. to play, to see, to sleep) for learners who have studied this grammar before.

Infinitives

Some verbs require the use of the infinitive marker “to”, when followed by another verb. The second verb will be in the infinitive.

Examples:
I hate to bother you. (Not: I hate bother you)
If you decide to apply for the job, then give me a call. (Not: If you decide apply, ….)
She refuses to answer the question. (Not: She refuses answer the question).

Other verbs that are commonly followed by “to + infinitive verb” are: choose (to), promise (to), intend (to), hope (to), expect (to), plan (to), seem (to).

Note: Using any of these words does not automatically require the use of “to + infinitive verb”. We do not use “to” when there is no other verb in the sentence.

Examples:
I hate broccoli. (Not: I hate to broccoli.)
She promised me. (Not: She promised to me.)
He expected them. (Not: He expected to them.)

Gerunds

A gerund is the -ing form of a verb used as a noun.

Verbs that are commonly followed by a gerund are: detest, enjoy, avoid, miss, keep, remember, consider, suggest.

Examples:
I avoid driving at night. (Not: I avoid to drive at night.)
I enjoy gardening. (Not: I enjoy to garden.)  “gardening” could also be viewed as a noun.
She denies calling him that night. (Not: She denies to call him that night.)
I am considering leaving my current job. (Not: I am considering to leave.)
I keep thinking it’s Wednesday. (Not: I keep to think…)
I don’t remember leaving my wallet in my car. (Remember + gerund = recall a past action. Remember + infinitive = not forget to do something: Remember to lock your car.)

Note: Not every verb ending with -ing is a gerund.

I enjoy baking. (Gerund)
I am baking. (Present participle, not gerund!)
