infinitive

An ‘infinitive’ is the basic form of a verb that usually goes after ‘to’.
Usually, when we say ‘infinitive’ we mean the most common: present infinitive after ‘TO’ (the basic/base form of verbs that we learn first or find in dictionaries).
The infinitive can also take a perfect, continuous, and passive form or a combination of those.

It can function as a noun, adjective, or adverb

like | want (verb patterns)

Like and want are transitive verbs that can take objects. For example, “I like football” and “I want money.”

After like, we can use either the to-infinitive or the -ing form. For example, “I like to use the internet” and “I like using the internet” are both correct.

After want, we can only use the to-infinitive. For example, “I want to use the internet” is correct, but “I want using the internet” is wrong.

The choice between the to-infinitive and the -ing form after like can convey subtle differences in meaning. Using the to-infinitive emphasizes the preference or habit, while using the -ing form emphasizes the action itself and the experience or enjoyment derived from it.

In the English Grammar Profile, A1 point 2 in the category of VERBS/patterns is defined as ‘like’ followed either by a ‘to’-infinitive or an ‘-ing’ form, with no change in meaning.

A1 point 6 in VERBS/patterns is defined as ‘limited range of verbs followed by a ‘to’- infinitive.

The most common verbs followed by a to-infinitive after like are: use, work, play, see, go, get, make, take, watch, read.

Here are some examples of sentences using like and want in A1 English:

I like to use the internet.
I want to go to the movies.
I like playing football.
I want to learn English.
