Muddled priest showing little spirit (6)
I believe the answer is:
sprite
'little spirit' is the definition.
'sprite' can be an answer for 'spirit' (thesaurus). I'm not certain of the 'little' bit.
'muddled priest' is the wordplay.
'muddled' is an anagram indicator.
'priest' anagrammed gives 'SPRITE'.
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for sprite that I've seen before include "sports car" , "Goblin, elf or imp" , "Dainty type" , "Naiad" , "water pixie" .)
