Wherein to fight for a warm-hearted woman (5)
I believe the answer is:
arena
'wherein to fight' is the definition.
I can't tell whether this definition defines the answer.
'a warm-hearted woman' is the wordplay.
'a warm' becomes 'toast' (toast can mean to heat up).
'hearted' says to take the centre.
'woman' becomes 'rena' ().
The central letter of 'toast' is 'a'.
'a'+'rena'='ARENA'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for arena that I've seen before include "Field of combat" , "Where gladiators fought" , "Sit around here being entertained" , "Battleground" , "bowl? Possibly" .)
