Enraged Eve rang one to settle score (7)
I believe the answer is:
avenger
'one to settle score' is the definition.
I can't judge whether this defines the answer.
'enraged eve rang' is the wordplay.
'enraged' is an anagram indicator.
'eve'+'rang'='everang'
'everang' with letters rearranged gives 'AVENGER'.
Can you help me to learn more?
(Other definitions for avenger that I've seen before include "He seeks satisfaction or retribution" , "One exacting payback on another's behalf" , "Hillman" , "Mrs Peel?" , "One doing harm to get their own back" .)
