A minder turned out to be native (7)
I believe the answer is:
amerind
'be native' is the definition.
Although both the answer and definition are adjectives, I cannot see how they can define each other.
'a minder turned out' is the wordplay.
'turned out' indicates an anagram (turn out can mean to organise).
'minder' with letters rearranged gives 'merind'.
'a'+'merind'='AMERIND'
'to' is the link.
Can you help me to learn more?
(Other definitions for amerind that I've seen before include "A native of the Americas" , "US native" , "US inhabitant" , "One from the New World" , "Indigenous American" .)
