The most common place to find gerunds and infinitives in English is in the object position, after the main verb. For example:
- I enjoy reading historical novels.
- We plan to go snorkeling next weekend.
- I promised to buy a bigger diamond for my wife on our fifth anniversary.
- Doctors recommend sleeping at least seven hours a night.
With each of these main verbs, you have no choice. Enjoy and recommend must be followed by a gerund. Plan and promise must be followed by an infinitive***.
There is another group of verbs that can be followed by either the gerund or the infinitive form of the verb. For example:
- It started to rain an hour ago. / It started raining an hour ago.
- I will continue to study Spanish next year / I will continue studying Spanish next year.
- Japanese people prefer to take baths at night. / Americans prefer taking showers in the morning.
In all of these examples, either sentence is ok and both sentences have the same meaning. However, sometimes either the gerund or the infinitive is better depending on the grammatical structure of the rest of the sentence. For example:
- It is starting to rain.
- It is starting raining.
To me, the first choice is ok but the second choice is bad because the gerund-gerund construction sounds weird. In the sentence The children are practicing writing in cursive, the gerund-gerund construction is unavoidable (sort of) because practice can only be followed by a gerund and you must use practicing because it is the continuous tense. However, with starting, you have a choice, so don't put two gerunds together. (I would eliminate writing to avoid the weird construction. The children are practicing cursive.) Here is another example of a weird structure you should try to avoid if possible.
- It is going to start to rain in a minute.
- It is going to start raining in a minute.
In this case, the sentence with to rain is a poor choice because the main verb, start, is also following to. (However, to start is not an infinitive. Is going to is a helping verb that is basically the same as will.) The second choice, to start raining, is much better. A good general rule of thumb is "avoid repetition whenever possible." (Unless, of course, there's a good reason to be repetitive. Ain't English fun?)
There is a small group of verbs that can be followed by either a gerund or an infinitive, but the meaning changes depending on which you use. This is the main point of the blog. (Finally, huh?) I will explain each one in more detail.
Like to do or Like doing?
In reality, the difference between the two is small enough that I generally say "Don't worry about it." You can use either form and nobody would really care. However, if you really want to be accurate, here's the difference.
- I really like to swim in the ocean.
- I really like swimming in the ocean.
In this case, the second choice, swimming, is the better choice because in this situation, like means enjoy. The chance to swim in the ocean is something I get excited about. Since enjoy must be followed by a gerund, it is better to use the gerund form when you are talking about a fun activity. On the other hand:
- Most Americans like to take a shower in the morning.
- Most Americans like taking a shower in the morning.
In this situation, the first choice, to take, is better because like means prefer. I don't jump up and down in anticipation of my morning shower. I don't go to bed dreaming about it. However, if you give me a choice, taking a shower in the morning is preferred. I just don't feel right if I don't.
If you were in my class taking a test, I wouldn't care either way. I don't think about this when I write or speak. In the immortal words of Gus Portokalos in My Big, Fat, Greek Wedding, "There you go." The next pairs, on the other hand, you do need to pay attention to.
Remember/Forget to do or Remember/Forget doing?
One of these means I'm going to get into trouble. The other means I have had a great experience.
- I forgot to do my homework.
- I will never forget watching the sun rise from the top of Mt. Fuji.
On the other hand, I've been very lucky to have had many wonderful experiences in my life. For example:
- I remember riding an elephant through the hill country of northern Thailand.
- I will never forget shaking Jimmy Carter's hand or meeting my wife for the first time.
The older I get, the more I look back on my life using gerunds.
Try to do or Try doing?
If I want to get ahead on my homework by finishing my research paper a week early, I would say:
- I will try to finish my research paper by Monday.
If my friend wants me to call him on Friday evening, but I think I might be out late, I would say to him:
- I will try to call you tonight.
Try to do means you want to do something, but you might not be able to. Try to do means you are not sure you will be able to keep a promise. Tried to do in the past tense is very often misused by non-native speakers. For example, a second-language learner might say:
- I tried to get a part-time job last summer.
What they mean to say is that they did get a part-time job and worked all summer. However, because of the verb tried, what they really say is they failed. They couldn't get a job. What they should say is:
- I got a part-time job last summer.
Short, sweet and factual. On the contrary, if there is something you've always thought about doing, but have never done, you would say:
- I would love to try skydiving.
Or if you did something for the first time on a really fun trip, you could say:
- I tried snowboarding for the first time in New Zealand.
Try doing is used for experiments, for something you are doing for the first time. If you are cooking a difficult dish for the first time, you will try making it. If you want to exercise your brain, you should try learning a foreign language. Success or failure depends on a gerund or an infinitive.
Stop to do or Stop doing?
The following sentences describe something I would say to my students during a test, something I did because I got old and something my mother said to me quite often when I was young.
- Stop talking!
- I stopped playing rugby.
- Stop hitting your brother!
When an activity is finished, you stop doing it. The following sentences describe what happened while I was driving to the North Shore, something that happened while I was writing this blog and something my father had to do frequently while we were driving from Pennsylvania to Texas. (Good Lord, those were long trips.)
- I stopped to admire the gigantic waves.
- I stopped to change a stinky diaper.
- He stopped to yell at my brother and me because we were fighting.
Stop to do explains why you interrupted what you were doing in the first place. Why did you stop?
Regret to do or Regret doing?
Everyone has done stupid things that they wish they hadn't done. Unfortunately, I have probably done more stupid things than most people. For example:
- I regret not asking Denise Brown out when I was in tenth grade. (Man, I was an idiot.)
- I regret spending so much money in Roppongi on weekends.
- I regret buying a laser disk player.
I just hope my wife never regrets marrying me. Regret to do is much less common and is usually used with the verbs inform or tell. It is used when you have to tell someone bad news.
- I regret to inform you that your credit card was declined.
- I regret to tell you that you will have to repeat this course in summer school.
Just like hitting a backhand or making a free-throw, it will take some practice and some concentration, and you will fail sometimes, but over time, you will fail less and less and you will learn to use these patterns correctly.
========================================================
*To make a gerund you add ~ing to the base form of a main verb. Sometimes you need to double the last consonant (CVC), and sometimes you need to drop the final "e".
- fishing / jumping / thinking
- running / getting / planning
- taking / smiling / biting
**To make an infinitive you simply put to in front of the base form of the verb.
- to fish / to run / to smile
