Fighting and giving a cry of pain in the arena (6)
I believe the answer is:
rowing
'fighting and' is the definition.
I can't judge whether this defines the answer.
'a cry of pain in the arena' is the wordplay.
'a cry of pain' becomes 'ow' (I've seen this in other clues).
'in the' means one lot of letters goes inside another.
'arena' becomes 'ring' (I've seen this in other clues).
'ow' going inside 'ring' is 'ROWING'.
'giving' is the link.
Can you help me to learn more?
(Other definitions for rowing that I've seen before include "in dispute" , "Steven Redgrave's sport" , "Olympic event" , "Using oars" , "Sport associated with Henley" .)
