Brown room? (5)
I believe the answer is:
study
This clue might be a double definition.
'brown' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'room?' is the second definition.
(study is a kind of room)
Can you help me to learn more?
(Other definitions for study that I've seen before include "Room for work/reading" , "Read to learn" , "Dusty (anag.)" , "Examine carefully" , "Scrutinise" .)
