Home for a queen (4)
I believe the answer is:
hive
'home for a queen' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hive that I've seen before include "Place swarming with activity" , "Bee colony" , "busy scene" , "Bee box" , "Insects' home - site of much activity" .)
