The Verb-ing form is also referred to as a gerund. It is a verb with its “ing” form that is used as the name of an activity, and it can be used with any action verb given. Whereas the infinitive works as other parts of speech in the sentence and it is formed by using to in front of the base verb that you want to use.

Grammar Explanation: -ing Forms and Infinitives
The -ing and infinitive forms of verbs are very common in English and can act as subjects, objects and complements of verbs. When used like nouns, -ing forms are often referred to as ‘gerunds’. This unit looks at the use of -ing forms and infinitives after certain verbs, determiners, adjectives and nouns, and at the special use of infinitives to describe purpose and result. (For the use of -ing and infinitive forms in clauses and phrases and in the passive and perfect forms of participles and infinitives).
As subjects and objects
We can use -ing forms of verbs in the same way that we use nouns – as the subject, object or complement of a verb. We often refer to-ing forms used in this way as gerunds:
- Swimming makes you fit.
- The whole family has taken up cycling.
- Lying is her worst habit.
Sometimes -ing forms can have their own subjects and objects:
- I’m looking forward to my wife returning (subject + -ing form)
- Meeting new people is one benefit of taking evening classes (-ing form + object)
We can make a negative with not + -ing:
- Not getting a refund on faulty goods is what really annoys me.
Note: But we use no + -ing to explain that something is impossible or not allowed:
X There’s not smoking in this office/ There isn’t smoking in this office.
✓ Could you go outside? There’s no smoking in this office.
- There’s no skiing here in the summer season. (= Skiing is impossible.)
- No Parking (= Parking is not allowed here.)
-ing form patterns
We can use determiners, eg. the, this, possessives, e.g. Peter’s: possessive adjectives, e.g. his: or object pronouns, e.g. him, before -ing forms. Object pronouns are more common in informal English:
- All this complaining won’t get you anywhere, you know.
- Peter’s complaining didn’t do him any good.
- Exorbitant tax rates led to his leaving the country.
- Exorbitant tax rates led to him leaving the country. (informal)
We often use an object + -ing form after verbs of the senses :
- I heard Alagna giving a marvellous rendition of ‘Nessun Dorma’
Note: We always use the object pronoun after sense verbs:
X Have you seen our performing yet?
✓ Have you seen us performing yet?
Note: When we use the + -ing form and we want to link it with an object, we use of:
X The giving presents is a traditional part of the Christmas festivities.
✓ The giving of presents is a traditional part of the Christmas festivities.
We also use -ing forms as adjectives
- The remaining items will be sold in our January sale.
Many adjectives and nouns are followed by a preposition + -ing form:
- Lara isn’t capable of lying and she has no reason for not telling the truth.
Infinitives with to can be the subject, object or complement of a verb:
- To give is better than to receive. Everyone loves to win.
We make a negative with not + infinitive:
- I tried not to look at the accident.
An infinitive can have its own subject, introduced with for:
- For evil to succeed it is only necessary for the good to do nothing.
Note: In informal English, we sometimes put an adverb between to and the infinitive. This is known as a ‘split infinitive’ and we usually avoid it in formal English by putting the adverb in another position:
- The doctor started to carefully remove the bandages.
✓ The doctor started to remove the bandages carefully.
There are also perfect, continuous and passive forms of the infinitive. If, for example, the person who is doing the action described by the infinitive is not the subject of the sentence, we usually use the passive infinitive:
X The report is to hand in first thing tomorrow morning.
✓ The report is to be handed in first thing tomorrow morning.
Infinitives of Purpose and Result
We can use an infinitive to describe the purpose or reason for an action:
- Cover the turkey in silver foil to keep the meat moist.
- To stop the train, pull the lever downwards.
We use for before the infinitive when the subject of the infinitive is different from the subject of the sentence:
X She went to Walmart for to get some groceries.
✓ She went to Walmart to get some groceries.
✓ We bought a cage for John to keep his hamster in.
In more formal English we can use in order or so as to + infinitive of purpose:
- Interest rates have been raised in order to reduce inflationary pressures.
- We have removed the warning signs so as not to alarm members of the public.
The infinitive can also describe a result or something surprising, especially with only and verbs such as find, discover, realize, etc.:
- They queued for hours at the box office only to discover that the show was sold out.
We also use infinitives after too and enough to talk about results:
- That blue outfit was too informal to wear to the reception.
- There isn’t enough (food) to go around, I’m afraid.
Infinitives after adjectives and nouns
Many adjectives, especially those describing feelings, can be followed by to + infinitive (some common examples are in the box below):
- We’re thrilled to welcome this year’s prize winner onto the podium.
- The Bensons are lucky to be having such good weather.
adjective + to + infinitive: able / unable, afraid, anxious, ashamed, bound, careful, certain, crazy, curious, due, eager, fit, happy, impossible, likely, lucky, pleased, right, shocked, stupid, sure, surprised, thrilled, welcome, wrong.
Many nouns can be followed by to + infinitive (some common examples are in the box below):
- She’s finally made a decision to leave.
- Clare would be a fool to marry him.
noun + to + infinitive: attempt, bid, decision, desire, incentive, need, nuisance, opportunity, place, pleasure, reason, time, wish.
Note: We can use a noun + to + infinitive after there is / are and have (got) to express an obligation:
- Don’t disturb me, I’ve got a report to write this evening.

With some of these verbs (marked * in the box below), we can also put an object before the -ing form. Compare:

Verb + -ing Form/ Infinitive
Some verbs can be followed by an -ing form or an infinitive, with no difference in meaning:
- I can’t stand to see/ seeing animals in pain.
verb + -ing form or infinitive: attempt, begin, bother, can’t bear, can’t stand, cease, continue, deserve, fear, hate, intend, like (= enjoy), love, prefer, start.
Note: We usually avoid putting two infinitives or two -ing forms together:

✓ He wanted to start taking lessons.
We use to + infinitive after would like, would love and would hate:
X When we get there I would like taking a nap.
