Conflict concerning new underground accommodation (6)
I believe the answer is:
warren
'underground accommodation' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'conflict concerning new' is the wordplay.
'conflict' becomes 'war' (war is a kind of conflict).
'concerning' becomes 're' (both can mean on a particular topic).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'war'+'re'+'n'='WARREN'
Can you help me to learn more?
(Other definitions for warren that I've seen before include "Area of rabbit burrows" , "Colony of rabbits" , "Network of caves as built by rabbits" , "Rabbit home" , "Rabbit burrow" .)
