Score-settler against English in rage (7)
I believe the answer is:
avenger
'score-settler' is the definition.
I can't judge whether this definition defines the answer.
'against english in rage' is the wordplay.
'against' becomes 'v' (abbreviation for 'versus').
'english' becomes 'E' (abbreviation).
'in' means one lot of letters goes inside another.
'rage' becomes 'anger' (I've seen this in another clue).
'v'+'e'='ve'
've' inserted into 'anger' is 'AVENGER'.
Can you help me to learn more?
(Other definitions for avenger that I've seen before include "One who exacts reparation for a wrong" , "Inflicter of retribution" , "Someone wanting to get even" , "one retaliating" , "Bringer of retribution" .)
