The one under protection got peer in trouble
I believe the answer is:
protege
'the one under protection' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'got peer in trouble' is the wordplay.
'in trouble' is an anagram indicator.
'got'+'peer'='gotpeer'
'gotpeer' with letters rearranged gives 'PROTEGE'.
Can you help me to learn more?
(Other definitions for protege that I've seen before include "One guided and protected by another" , "Favoured pupil" , "One guided and supported by another" , "Blue-eyed boy" , "One under the patronage of another" .)
