The regular verb enjoy means ‘get pleasure from something’. It usually has an object:
We enjoyed the movie so much.
Enjoy your holiday in Ireland.
Not: Enjoy in Ireland.
We also use enjoy to talk about getting pleasure from a situation we are in. In this case, we say enjoy myself, yourself, herself, himself, etc.:
Did you enjoy yourself last night?
We always enjoy ourselves when we go to Lynn’s house.
We use the -ing form after enjoy but we don’t use a to-infinitive:
I never enjoyed cycling.
Not: I never enjoyed to cycle.
They enjoyed meeting people on their trip around Italy.
Not: They enjoyed to meet people on their trip …
In informal situations, enjoy is sometimes used on its own without an object. This is especially common in American English:
A:We’re now going out for dinner.
B:Enjoy!
