Withdraw a claim, finding defender depressed (4,4)
I believe the answer is:
back down
'withdraw a claim' is the definition.
'back down' can be an answer for 'withdraw' (backing down is a kind of withdrawing). I am not certain of the 'a claim' bit.
'defender depressed' is the wordplay.
'defender' becomes 'back' (I've seen this before).
'depressed' becomes 'down' (synonyms).
'back'+'down'='BACK DOWN'
'finding' is the link.
Can you help me to learn more?
(Other definitions for back down that I've seen before include "Withdraw argument or avoid confrontation" , "Concede defeat" , "Abandon one's position" , "Withdraw (aggressive) claim" , "admit defeat" .)
