Talk to man in labyrinthine building (6,6)
I believe the answer is:
rabbit warren
'labyrinthine building' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'talk to man' is the wordplay.
'talk' becomes 'rabbit' (rabbit can informally mean to talk).
'to man' becomes 'warren' ().
'rabbit'+'warren'='RABBIT-WARREN'
'in' is the link.
Can you help me to learn more?
(Other definitions for rabbit warren that I've seen before include "Bunnies' home" , "Group of burrows" , "Cony burrow" , "Bunny home" , "Bunny's subterranean maze" .)
