What gets me as a non-native speaker far more than "a vs an" is the "a vs the" conundrum. I still don't quite get when something needs to be "indefinite" and I've been speaking English for close to forty years. My native tongue lacks articles altogether and it's soo bloody hard I feel hopeless I'll ever master them fully.
I was going to start by stating the difference is “a” is unspecific, “the” implies the subject is already known.
However as I thought more about it I realized it gets a little more complicated. I’m not academically studied in English, though I am a native speaker.
For example if you say, “Our town has a castle” - that’s a specific castle but you wouldn’t say “our town has the castle.”
Why? It has to do with what the listener knows. “Definite” means the subject is known to the listener. If I’m introducing a castle into the conversation that you don’t know, I’m talking about _a_ castle. Now that it’s introduced, I can tell you about _the_ castle.
It's because the town has one out of the set of all castles.
You can also say "Our town has the castle", which... now there it gets weird. I think it means it doesn't have much, but it has that. Well I guess it's specific in that it is one of the few (specific) things it has going for it.
I would take "Our town has the castle" to imply that there's a group of towns that collectively only have one castle, and your town is the one that has it.
Compare: "Sacramento is the capital." You could say Sacramento is a capital if the reference group includes Albany, Austin, Tallahassee, etc. Or you could say Sacramento is the capital if the reference group includes Los Angeles, San Diego, San Francisco, etc.
