Play / Have Fun / Enjoy / Hang Out

[english grammar man]

Play without an object is only used with children. Often in my ESL classes, my adult students use the word "play" when describing how their recent weekend was.

Example:

- Can Jimmy come out and play?
- The children are playing in the yard.

Adults "have fun" or "relax" or "enjoy themselves" or "hang out / around" or "go".

Example:

- I had a lot of fun when I was a student.
- I go to the city every Saturday night.

NOTE:
The word "enjoy" is not really very popular in English. We prefer "like".

Example:

- I enjoy studying English. -> I like studying English.
