Introduction to gerunds and infinitives

Consider the differences in meaning between the following sentences:

• Watching a lot of tv is not good for you!• I want to watch The Simpsons at 8.• Saving money is hard.• My parents want to save 2000 euros this

year.• I love playing football.• We are going to play football tomorrow

What is a gerund and what is an infinitive?

• A gerund is a word that ends with –ing

• An infinitive is combination of to + verb

• For example to buy, to show, to find etc


• Watching a lot of tv is not good for you!

• Reference to the activity

• Specific intention

• I want to watch The Simpsons at 8.


Saving money is hard.

Reference to the

activity• Specific intention

• My parents want to save 2000 euros this year.


I love playing football.

Reference to the activity• Specific intention

• We are going to play football tomorrow

What is a gerund?

• A gerund = a reference to the activity.• A gerund is a word with –ing that refers to

an activity in general NOT a specific moment or intention. Examples:

• I love travelling!• Buying a house is complicated.• Getting up early is not easy.

What is an infinitive?

• An infinitive= a verb + to= to go, to buy• An infinitive= a specific intention to do an

action at a specific moment.• We need to buy the ticket tomorrow.• I need to show you something now.• What do you want to do tomorrow?

Important rules for the infinitive

• Exceptions for the infinitive= MUST + CAN• Must or can never take “to”• Examples:• I can do it never I can to do it

• We can’t find it never I can’t to find it

• We must show her never we must to show her


• Look at the following incorrect sentences

• I came for to tell you the news• For to go there, you need a car• I am here for to show you what to do.


• The infinitive is already two words in English. To go, to buy etc.

• When you are speaking about a logical progression of events it is not necessary to put for in front of the infinitive= for to go there.

• I came to tell you the news• To go there, you need a car• I am here to show you what to do.
