What is a Gerund

• Gerunds are formed by adding “-ing” to the verb: “sleeping,” “drawing,” “swimming.” But they are not the “-ing” verb forms that you see in the present or past continuous tense. 
• They look the same, but gerunds are actually verb forms used as nouns.

Gerunds are formed by adding “-ing” to the verb: “sleeping,” “drawing,” “swimming.” But they are not the “-ing” verb forms that you see in the present or past continuous tense. They look the same, but gerunds are actually verb forms used as nouns.

Let’s take the infinitive of the verb “to sleep” and use it in two different sentences: I am sleeping.

This is the present continuous. “Sleeping” here is part of the verb. It is not a gerund. 

Here’s the second sentence: I don’t like sleeping.

This is present simple, but it contains a gerund. “Sleeping” is the direct object of this sentence.

 Gerunds can be used as a subject of a sentence.

EXAMPLES

Eating people is wrong.

Hunting tigers is dangerous.

Flying makes me nervous.

Brushing your teeth is important.

Smoking causes lung cancer.

 Gerunds can be used as an object of a sentence.

You may say: “I enjoy drawing.”

You may also say: “Yesterday, I decided to draw.”

Both sentences are correct, but one has an infinitive as the object and the other has a gerund as the object.

Some verbs require a gerund and some will require an infinitive. 

In the examples, we can see that the formula is “enjoy” + [gerund] and “decide” + [infinitive].

With practice, you will be able to remember which one is which.

Here are a few examples of verbs that need to be followed by an infinitive:

agree: I agreed to go to a party with my friend.

decide: The president decided not to participate in the discussions.

deserve: Everyone deserves to be respected.

expect: I expect to know my exam grade by tomorrow.

hope: We were hoping to avoid traffic by leaving early.

when to use a gerund?

Gerunds (ing)

1. After a preposition - She is good at playing games.
2. When it is the subject of the sentence - Smoking is bad for your health.
3. After some verbs (verbs of preference: hate, don't mind , like) - I don't mind running in the rain.

Gerunds and Infinitives

Gerunds are nouns formed from verbs. Gerunds are formed by adding –ing to the end of a verb. Some examples are eating, playing, and listening. Infinitives use to before the verb so the examples above would be to eat, to play, and to listen. Both can be used as the subject or object of a sentence. 

to + infinitive

 when to use it?

1. After adjectives - My house is easy  to find.
2. To express purpose  - She is saving money to travel 
3. After some verbs (want, need , learn, hope, expect, decide ) - I want to ride my bike

Using the infinitive without "to" 

1. Any modal verbs; (would, could, might, must) - I might go home. 
   
2. With the verbs; make/let - I make him walk the dog 

We let them win at football because they were only little children.
