Bully-boy grew up, lived and died here (9)
I believe the answer is:
labyrinth
'died here' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'bully-boy grew up lived and' is the wordplay.
I cannot really see how this works, but
'boy' could be 'ab' and 'ab' is present in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for labyrinth that I've seen before include "listening equipment" , "Complex network of passages" , "Complicated network of passages or paths" , "perplexity?" , "It may be difficult to get out of" .)
