Ring performer to spoil her gift (7)
I believe the answer is:
fighter
'ring performer' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'spoil her gift' is the wordplay.
'spoil' is an anagram indicator.
'her'+'gift'='hergift'
'hergift' with letters rearranged gives 'FIGHTER'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for fighter that I've seen before include "Fast military aircraft" , "See 12" , "Combat aircraft" , "Professional boxer - a person with determination" , "Boxer; warrior" .)
