The grammatical principle -에 can be attached to nouns to indicate where or when something is happening. It attaches right to the end of the noun, with no special rules or alterations to the noun. It can be translated as “at”, “on”, or “in” depending on the usage, but the meaning is all the same really. Fairly simple stuff.

It can also be used to mean “to”, as in “I walked to school.” The verb used together with it in the sentence will sometimes help make it clear if that’s the usage you’re seeing. For example, you wouldn’t say “I’m going at school.” you’d say “I’m going to school.”

Some other particles can be attached to this one as well. Most commonly -도, meaning “too”, “neither”, or “even”. You’ll see a couple of examples of this below.
