District must accommodate new stadium (5)
I believe the answer is:
arena
'stadium' is the definition.
(I know that stadium can be written as arena)
'district must accommodate new' is the wordplay.
I cannot really understand how this works, but
'new' could be 'n' (common abbreviation eg NT for New Testament) and 'n' is found in the answer.
'district' could be 'area' (I've seen this before) and 'area' is present in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for arena that I've seen before include "sports ground" , "Battleground" , "Place of public contest" , "Coliseum" , "Scene of gladiatorial contest, perhaps" .)
