How do I know if дверь в комнату is "to the room" or "in the room"?
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.
Thanks!
Very good comment, thanks!
to the room :в комнату in the room :в комнатe
What about "дверь комнаты"?
What about "дверь к комнате"?
Russian people don't say "дверь к комнате". It's not correct
in my grammar book на means 'to' in this sentence
