why is it that we can structure a sentence like “I’m in school” but not “I’m in nightclub”?

Question

Some nouns have to have “the” before it but seems like not all of them need it, so any explanations would be helpful!

edit: wow, didn’t expect so much traction on this. Thank you for your explanations! Interestingly, I’m actually a native English speaker but don’t really know grammar terminology all that well. Thanks for sharing your knowledge!

I thought it’s “I’m at school” and also, there’s only really one school you can be going to at a time, which is defined in the word itself. If you say “I’m at a school” it has a different meaning. Someone who’s touring schools and teaching things could say they’re at a school.
