Gerunds and Infinitives
after prepositions and adjectives


Preposition + Gerund

After a preposition, we always use a noun or the -ing form of a verb - the gerund. For example:

I'm very good at speaking English.

I went home after finishing my work.

Adjective + Infinitive

After many common adjectives, we often use "to + verb" - the infinitive. For example:

It's rude to eat with your mouth open.

It's difficult to remember all this grammar.

Unfortunately, this isn't always true, but it is a useful, general rule.


Don't forget that "to" can also be a preposition, not just part of the infinitive. For example:

I'm looking forward to seeing you this weekend.

I'm used to getting up early in the morning.

I object to smoking in public.

He confessed to stealing the money.

It's difficult to know when it's a preposition - just try to learn expressions like these when you see them.
