TV room (3)
I believe the answer is:
den
'tv room' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for den that I've seen before include "Hidden lair of an animal" , "Animal lair or gent's study" , "Habitation of wild animals (3)" , "Wild animal's home" , "Room for work or play" .)
