Help cure an eccentric creature of folklore (10)
I believe the answer is:
leprechaun
'creature of folklore' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'help cure an eccentric' is the wordplay.
'eccentric' indicates an anagram.
'help'+'cure'+'an'='helpcurean'
'helpcurean' with letters rearranged gives 'LEPRECHAUN'.
Can you help me to learn more?
(Other definitions for leprechaun that I've seen before include "He helps Irish housewife" , "Mischievous Irish sprite" , "Elf in Irish folklore" , "Mischievous Irish elf" , "Mischievous imp" .)
