Hi Armsys
The is not used when
school is used to indicate
learning:
He still goes to school.
He doesn't like school.
I don't have to go to school today.
School will be over at half past three.In other cases an article is needed:
I went to the school yesterday to see my son. (I am a parent, I went to see my son at
the school.)
A new school has been built in Nothingville. (= a building)
Similar thinking helps choose the article with some other words as well:
He goes to church on Sundays. (He attends a divine service.)
I'll meet you at the church tonight. (We think of the building only. We need not go indoors at all. We certainly won't attend a religious service.)
He is in hospital. (AmE:
He is in the hospital.) (He is a patient.)
He works at a/the hospital. He is in jail/prison. (He is a prisoner.)
He works at a jail/prison.CB
