Impish type converted by priest (6)
I believe the answer is:
sprite
'impish type' is the definition.
(I've seen this before)
'converted by priest' is the wordplay.
'priest' can be anagrammed to 'SPRITE'.
But, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for sprite that I've seen before include "Puck, say" , "Pet, sir, could be a goblin" , "Naiad" , "Elf, fairy" , "Dainty type" .)
