Gerunds or Infinitives?

Part I

The basic difference between gerunds andinfinitives is the following:

Using a gerund suggests that you are referring
to real activities or experiences.
Using an infinitive suggests that you are
talking about potential or possible activities or experiences.

So let's say youeat ice cream every day. This is an actual action you are doing. Then you could say: "I like eating ice cream".
On the other hand, if you are on a diet, and you don't usually eat ice cream,then you are talking about a potential action. You could say: "I like to eat ice cream."
When used before the main verb, gerunds tend to sound more like natural English.
For example, the sentence "Playing tennis is a lot of fun" sounds more natural than"To play tennis is a lot of fun". The later sentence sounds more theoretical.

Part II

After the main verb, both gerunds and infinitives can be used.
Themain verb in the sentence determines whether you use a gerund or an infinitive.
Some verbs can take both gerunds and infinitives, with only a slight difference in the meaning (as explained inPart Iabove).
A fewverbs take both gerunds and infinitives, but with an significant difference in the meaning.

Part III

So when you need to decide which one to use, first check whether the main verb is limited only to gerunds, or only to infinitives.
If the verb is not on any of the lists, you can use the following guidelines:

  • The word"go" + sports or recreational activitiesusually take a gerund.
    Examples: "Let'sgo shopping", "Theywent skiing".
  • After a prepositionyou should use a gerund.
    Examples: "I will talk with youbefore goingto lunch" "I am looking forwardto workingwith you".
  • Expressions with the words"have", "spend" and "waste"take a gerund.
    Examples: "Shehad fun skiing", "Hewasted all his time worrying".
  • In many cases, the infinitive form is used to show theintention orpurpose.
    Examples: "We are hereto help", "He leftto catch the train".
  • The infinitive form is also used to show thereason.
    Examples: "we were sadto hearabout your difficulties", "She was shockedto learnthe truth".
  • Ifneither of these guidelines apply, simply use the principle inPart Iabove.
    Does it describe aconcrete action? Then use a gerund.
    Does it describe ageneral or potential action? Then use an infinitive.
    Examples: "As a painter, I truly love painting",
    "I love to paint. I wish I would paint more often".

Anyhow, whenever you are in doubt,you can always use a dictionary to help you out!
