"a door to the room"

Translation: дверь в комнату

[itajaja]

How do I know if дверь в комнату is "to the room" or "in the room"?

[mightypotatoe]

В + accusative indicates direction (into, towards) and в + prepositional indicates location (in, inside). Here комнату is the accusative case, so it's "to the room." If it the door was inside the room it would be в комнате.

What about "дверь к комнате"?

[AkaBatoru]

Russian people don't say "дверь к комнате". It's not correct

[susanashe]

in my grammar book на means 'to' in this sentence
