I searched the meaning of prison on Goggle, and it gave an example sentence: "He died in prison." I wonder why there's no "a" or "the" before it when it's a countable noun, right?
Somebody broke out of (a/the/no article) prison.
Following the pattern, I think I should put no article, but I wanna know the reason.
Also, could you tell me the difference if I change the preposition "break out of/from." Why not "break out from"?
