Taking part in warfare, natives reveal battle ground (5)
I believe the answer is:
arena
'battle ground' is the definition.
'arena' can be an answer for 'ground' (I've seen this before). I am unsure of the 'battle' bit.
'taking part in warfare natives reveal' is the wordplay.
'taking part in' indicates a hidden word.
'ARENA' can be found hidden inside 'warfare natives reveal'.
Can you help me to learn more?
(Other definitions for arena that I've seen before include "Area of activity, boxing perhaps" , "Scene of gladiatorial contest, perhaps" , "Gladiatorial venue" , "Battleground" , "Venue for boxing, circus and other action events" .)
