Questions & Answers about На кухне гремит посуда, потому что мама готовит ужин.

Why is it на кухне and not в кухне for “in the kitchen”?

Both на and в can mean “in/at,” but Russian uses them in different fixed expressions.

• With кухня, the natural phrase meaning “in the kitchen (as a place where activity happens)” is на кухне (literally “on the kitchen,” but understood as “in/at the kitchen”).
• в кухне is technically possible but sounds strange in normal speech. It would suggest being inside the physical volume of the kitchen as a container, which isn’t how Russians usually conceptualize this room in everyday speech.

This is similar to other set phrases:

• на кухне – in the kitchen
• на улице – outside / in the street
• в комнате – in the room

So you simply have to memorize: “in the kitchen” = *на кухне* (prepositional case after на).

What case is кухне in, and why does it end with -е?
