で

at, in

indicates location of action; にて is the formal literary form

Noun (Location) + で

The particle で is used to indicate the location where an action or an event takes place. It is equivalent to 'at', 'in', or 'on' in English. It is specifically used for actions, not for indicating where something simply exists.

Location + で + Verb

Attach で directly after the noun representing the place where the activity occurs.

I eat at the restaurant.

I bought a book at the bookstore.

I ran in the park.

Note

The particle で cannot be used with verbs of existence like いる or ある. In those cases, the particle に must be used instead. For example, '図書館にいます' (I am at the library) uses に, but '図書館で勉強します' (I study at the library) uses で. In formal or literary writing, にて is sometimes used instead of で.
