Wit of a turbulent priest (6)
I believe the answer is:
esprit
'wit' is the definition.
(esprit can mean being witty)
'a turbulent priest' is the wordplay.
'a turbulent' indicates an anagram.
'priest' anagrammed gives 'ESPRIT'.
'of' acts as a link.
(Other definitions for esprit that I've seen before include "Vivaciousness" , "Lively and vivacious quality" , "Liveliness - priest (anag)" , "Stripe (anag)" , "Vivacity, liveliness" .)
