Venue in Aberdare named (5)
I believe the answer is:
arena
'venue' is the definition.
(I've seen this in another clue)
'in aberdare named' is the wordplay.
'in' indicates a hidden word.
'ARENA' is hidden in the letters of 'aberdare named'.
(Other definitions for arena that I've seen before include "place involving conflict?" , "Place of great activity" , "Scene of gladiatorial contest, perhaps" , "Stadium - battlefield" , "dramatic situation" .)
