Source of honey (7)
I believe the answer is:
beehive
'source of honey' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for beehive that I've seen before include "nickname of US State" , "Enclosure where honey is first made" , "unusually high overheads?" , "Get hairdo" , "Realm with queen, but not king" .)
