Other Grammar Rules

It can be tricky to remember which verbs are followed by the infinitive (the to form) of the verb and which are followed by the gerund (the ing form) of the verb. Sometimes the use of a gerund or an infinitive can change the meaning of a sentence.

Using Gerunds or infinitives

One of the difficulties of the English language is to know whether to use a gerund  (ex : doing) or an infinitive (ex : to do).

Generally speaking we can use the following rules:

Examples		Rules	Explanations
Verb + gerund	1. I enjoy playing 2. I denied stealing	Often we use the gerund for an action that happens before or at the same time as the action of the main verb.	1. I enjoy myself at the time of playing. 2. I deny having stolen anything before.
Verb + infinitive	1. I decided to visit my uncle 2. I want to go out	Often we use the infinitive for actions that followthe action of the main verb.	1. Visiting my uncle was an action of my decision. It comes after. 2. What I want (now) is to go out (after/later)

These rules are helpful but DO NOT always explain all uses of gerunds and infinitives.

Verbs commonly followed by a gerund

1- After verbs that express likes/dislikes :

• like
• love

Example:

Note "like/love/hate..." can be also followed by an infinitive:

Example:

2- After verbs  such as :
