Naturalist piloted priest around (13)
I believe the answer is:
lepidopterist
'naturalist' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'piloted priest around' is the wordplay.
'around' indicates anagramming the letters.
'piloted'+'priest'='pilotedpriest'
'pilotedpriest' is an anagram of 'LEPIDOPTERIST'.
Can you help me to learn more?
(Other definitions for lepidopterist that I've seen before include "Butterfly enthusiast" , "one with commas to check?" , "Butterfly expert" , "Student of moths and butterflies" , "One who studies butterflies and moths" .)
