Gerunds and infinitives

Some main verbs take a following gerund or infinitive – with slight nuances in meaning and slight contextual differences in use. Others take only one, depending on how the action is conceptualized in the language. These may vary in different languages, but that does not mean that each language views the action in a completely different manner, but rather, it is a matter of how these actions are profiled differently – the nuances and aspects of the action that are highlighted more.

The choice of using a gerund or infinitive form of a verb may depend significantly on the particular word it modifies, or a particular grammatical construction. In other cases, they may be fully interchangeable, with only a slight difference in nuance. In a few cases, both are possible, with a difference in meaning.

1 Examples

verb + GERUND	verb + INFINITIVE	verb + either (with different nuances)
consider anticipate discuss avoid	plan expect agree want	begin start like love prefer hate can't stand

2 Gerunds

Gerunds are traditionally treated as a type of noun, but modern syntacticians have differing views. Some regarded as a distinct mixed or in-between category with nominal and verbal features.

Taking exams is a waste of time.

This exam is a waste of time.(From Huddleston, 1983)

Noun-like because:
It can function as a subject/object	1a. Dancing is great fun. 1b. I like dancing
It can be modified by an adjective	1c. I like slow dancing
It can co-occur with a possessive form	1d. Homer's dancing was ridiculous
Verb-like because:
It can be modified by an adverb	2a. I like dancing slowly
It can take a direct object	2b. Dancing the tango is great fun 2c. I like dancing the tango

Context matters, also. Below, writing is more verb-like, as (1) it is modified by the adverbial actually, and (2) it takes a direct object NP (noun phrase).

Actually writing the email took only a few minutes

In the following, writing, is more noun-like, as (1) it is modified by an adjective and it is preceded a determiner, and (2) it is followed by a prepositional phrase (PP).

The actual writing of the email took only a few minutes

In this example, the gerund shows both verbal and nominal qualities.

They appreciate my visiting their parents regularly. (adapted from Greenbaum, 1992)

3 Dependent infinitives

The most common use for infinitives is the dependent infinitive after another verb, such as expressions of wishes, hopes, and intentions:

I just want to play on my drums all day. I hope to become a great drummer like Van Halen. So I plan to practice all day.

Infinitives are in a sense tenseless or not time-bound like other verbs; they don't refer to actual events so much as they refer to potential events, possible events, or events that haven't happened yet. Thus, they are used after main verbs like those above. Because of this semantic nuance, they are somewhat more abstract or generic (general) in meaning than infinitives or other forms of verbs.

4 Purpose clauses

Infinitives are used with purpose clauses, in which case they are similar to in order to. (The phrase in order to puts more emphasis on the purpose, or distinguishes a purpose infinitive from normal infinitives.)

He bought the car to impress his girlfriend. (in order to impress his girlfriend)

5 Interchangeable gerunds and infinitives

A gerund suggests an actual or real activity or experience that occurs (or would occur), while an infinitive implies a potential or possible activity or experience.

I like speaking Chinese when I'm in Chinatown.	≈ I enjoy the experience of speaking in Chinese.
I like to speak Chinese when I'm in Chinatown.	≈ I enjoy the option / ability / possibility of speaking Chinese
I tried speaking Chinese while I was in Taiwan.	≈ I tried actually speaking it
I tried to speak Chinese while I was in Taiwan.	≈ I attempted it – depending on the context, this may imply that I wasn't successful in doing so
I like living in Europe.	Implies that I actually have done so
I like to live in Europe.	Implies that I haven't done so, but would like to do so

In expressions like the following, they are interchangeable, with this sort of very slight nuance.

can't bear	He can't bear being alone.	He can't bear to be alone.
can't stand	Nancy can't stand working the late shift.	Nancy can't stand to work the late shift.
cease	The government ceased providing free health care.	The government ceased to provide free health care.
continue	She continued talking.	She continued to talk.
hate	He hates cleaning dishes.	He hates to clean dishes.
like	Samantha likes reading.	Samantha likes to read.
love	We love scuba diving.	We love to scuba dive.
neglect	He neglected doing his daily chores.	He neglected to do his daily chores.
prefer	He prefers eating at 7 PM.	He prefers to eat at 7 PM.
propose	Drew proposed paying for the trip.	Drew proposed to pay for the trip.

With these main verbs below, the choice between gerunds and infinitives depend on whether the dependent verb (the infinitive or gerund after the main verb, which depends on the main verb) has a subject. Expressing a subject with a gerund that is different from the subject of a main verb can be more wordy, or even awkward.

I advised seeing a doctor = I advised that they see a doctor; I advised them to see a doctor.

I advised their seeing a doctor: same meaning, but sounds awkward

advise	I advised seeing a doctor.	I advised them to see a doctor.
allow	Ireland doesn't allow smoking in bars.	Ireland doesn't allow people to smoke in bars.
encourage	He encourages eating healthy foods.	He encourages his patients to eat healthy foods.
permit	California doesn't permit fishing without a fishing license.	California doesn't permit people to fish without a fishing license.
require	The certificate requires completing two courses.	The certificate requires students to complete two courses.
urge	They urge recycling bottles and paper.	They urge citizens to recycle bottles and paper.

6 Significantly different gerund / infinitive meanings

With some main verbs, whether the following dependent verbal item is a gerund or infinitive changes the meaning altogether. For example, with the main verb stop, the type of following verbal item (which depends on the main verb) can have a very different meaning. With stop, the infinitive is a purpose infinitive (purpose clause, similar to in order to).

I stopped to buy some coffee.	= I stopped in order to buy coffee.
I stopped buying coffee.	= I no longer buy coffee (I quit drinking it; or it's too expensive)

	Gerund	Infinitive
begin	She began singing. She began to sing. When "begin" is used in non-continuous tenses, you can either use a gerund or an infinitive.	She is beginning to sing. When "begin" is used in continuous tenses, an infinitive is used.
dread	She dreaded taking the test. Usually "dread" is followed by a gerund.	He dreaded to think of the consequences of his actions. “Dread" is sometimes used with infinitives such as "think" or "consider." In the sentence above, "dreaded to think" means "did not want to think.”
forget	She forgot reading the book when she was a kid. When "forget" is used with a gerund, it means "to forget that you have done something." The sentence above means that she read the book when she was a kid, and that she has forgotten that fact.	She forgot to pay the rent this month. When "forget" is used with an infinitive, it means "to forget that you need to do something." The sentence above means that she forgot that she needed to pay the rent.
keep	She kept talking. “Keep" is normally used with a gerund to mean that you continue doing an action.	The attackers kept hostages to prevent the police from entering. “Keep" can also be used with an object followed by an infinitive, but then the infinitive takes on the meaning of "in order to..." In the sentence above, the attackers kept hostages in order to prevent the police from entering.
need	The house needs cleaning. When "need" is used with a gerund, it takes on a passive meaning (note: this may be considered more colloquial in style). The sentence above means "the house needs to be cleaned."	He needs to call his boss. He needs him to call his boss. “Need" is usually used with an infinitive or an object + an infinitive.
regret	I regretted being late to the interview. “Regret" is normally used with a gerund.	We regret to inform you that your position at the company is being eliminated. “Regret" is sometimes used with infinitives such as "to inform." In the sentence above, "We regret to inform you" means "We wish we did not have to tell you (bad news).”
remember	I remember mentioning the meeting yesterday. When "remember" is used with a gerund, it means "to remember that you have done something." The sentence above means that I mentioned the meeting, and that I remember the fact that I did that.	He remembered to turn off the lights before he left. When "remember" is used with an infinitive, it means "to remember that you need to do something." The sentence above means that he remembered that he needed to turn the lights off.
start	Marge started talking really fast. Marge started to talk really fast. When "start" is used in non-continuous tenses, you can either use a gerund or an infinitive.	Marge is starting to talk really fast. When "start" is used in continuous tenses, an infinitive is used. “I started to learn Russian, but it was so much work that I finally quit the class.” In other situations, an infinitive means that you did not complete or continue an action.
stop	He stopped smoking for health reasons. “Stop" is normally used with a gerund.	He stopped to rest for a few minutes. When "stop" is used with an infinitive, the infinitive takes on the meaning of "in order to." In the sentence above, he stopped in order to rest for a few minutes.
try	She can't find a job. She tried looking in the paper, but there was nothing. She tried asking friends and family, but nobody knew of anything. She also tried going shop to shop, but nobody was hiring. “Try + gerund" means to try or to experiment with different methods to see if something works. She tried eating the snake soup, but she didn't like it. "Try + gerund" is often used when you experiment with something, but you do not really like it or want to do it again.	She tried to climb the tree, but she couldn't even get off the ground. When you "try to do" something, you want to do it, but you do not succeed in actually doing it. In the sentence above, an infinitive is used because she cannot successfully climb the tree. Try not to wake the baby when you get up tomorrow at 5 AM. An infinitive is also used if you are asking someone to try something they may or may not be able to accomplish.

8 Infinitive and gerund clauses

8.1 Sentence roles

Infinitive clauses have nominal functions.

1. Direct object

1a. KJ wants to run his own language school

1. Subject complement

1b. KJ's aim is to run his own language school

1. Subject

1c. To run your own language school must be difficult

1. Subject clause extraposed

1d. It must be difficult to run your own language school

The use of infinitives, base forms, and gerunds is somewhat problematic for linguists. For example, the base form (some call it a bare infinitive, as if it were a second type of infinitive) is permitted with some verbs and not others; some verbs prefer full infinitives, others prefer base forms. For example, write in 2a is a base form – a verbal complement with no to infinitive marker.

2a. The professor helped write his statement of purpose.

2b. He hopes to visit India one day

3a. KJ helped to write the article.

3b. KJ helped write the article.[help takes either a full infinitive or a base form]

4a. Jay hoped to write the article.

4b. *Jay hoped write the article. [hope only takes an infinitive]

8.2 The base form (bare infinitive)

A number of common "perception" verbs (see, watch, hear, feel, sense etc.) take a direct object and a bare infinitive:

5a. KJ saw/watched/heard/ the accident happen.

Several common verbs of permission or causation, including make, let, and have take a base form complement.

5b. The professor made/let/had Jin Young rewrite her term paper

8.3 The full infinitive

To-infinitives are typically used after intransitive verbs:

6: a. I agreed to leave

To-infinitives can also be used after many transitive verbs; in this case, the infinitive generally has the direct object of the main verb as its subject:

6b. The professor persuaded KJ to rewrite her paper.

8.3.1 Subjectless infinitives

Many infinitive clauses lack an overt subject

7. She hopes to impress the professor with her term paper.

8.3.2 Infinitives with subjects

Other constructions involve an overt subject in the infinitive clause

8a. The dean asked the professors to revise their course objectives.

8b. The dean asked them to revise their course objectives.

8c. *The dean asked they to revise their course objectives.

Some verbs prefer an infinitive complement without an overt subject

9a. Most students try to study hard

9b. KJ continued to study all night

9c. Ricardo planned to study later

9d. Jean preferred to study now

9e. George refused to study at all.

Some verbs prefer an infinitive complement with an overt subject

10a. Dr. Frankenstein taught me to analyze syntax.

10b. The professor allowed Maria to submit her paper late.

10c. Bert hired a man to cut the grass.

10d. All the students implored the professor to grade generously.

10e. He reminded everyone to turn in homework on time.

Some verbs take either pattern.

11a. Everyone expected Freeman to win an Oscar.

11b. Freeman expected to win an Oscar.

11c. She loves the students to practice Korean with her.

11d. She loves to practice Korean.

11e. I want you to rewrite this.

11f. I want to rewrite this.

Some main verbs work better if the subject of the infinitive clause is introduced by for, a marker of infinitival subjects.

12a. He intended for her to revise the syllabus.

12b. ? He intended her to revise the syllabus.

12c. *The travel agent arranged me to visit Cheju.

Whether particular semantic or syntactic criteria or patterns for use of for with certain verbs seems unclear.

8.3.3 Gerund clauses have nominal functions

Direct object

13a. Natasha enjoys running her own language school

Subject complement

13b. Sun Hee's job is running her own language school

Subject

13c. Running your own language school is a great idea

8.4 Infinitives or -ing?

Infinitive complements are often associated with hypothetical and/or unfulfilled situations

14a. Raphael tried to go, but couldn't get the time off work.

Gerund complements are often associated with real, fulfilled situations

15. Raphael tried going, but didn't like it and left early

“Commitment" verbs generally take to-infinitive complements, either with or without subjects

16a. Sukki decided to leave.

16b. Maggie ordered her students to leave

Other verbs following this pattern:

17. allow, arrange, command, convince, hope, permit, persuade

Aspectual verbs (verbs that take a dependent verb to express special aspectual qualities, like beginning or ending an action) generally prefer gerund complements, but infinitive complements are possible.

18a. Natasha began/started working at dawn

18b. Natasha began/started to work at dawn

19a. Mirei continued/kept/remained working until lunchtime

19b. Mirei continued to work until lunchtime

19c. *Mirei kept/remained to work until lunchtime

20a. Homer ceased/finished working at five

20b. Homer ceased to work at five

20c. *Homer finished/ to work at five
