Hot priest shows wit (6)
I believe the answer is:
esprit
'wit' is the definition.
(I've seen this before)
'hot priest' is the wordplay.
'hot' indicates anagramming the letters (letters heated up or stimulated into a new order).
'priest' is an anagram of 'ESPRIT'.
'shows' is the link.
(Other definitions for esprit that I've seen before include "Vivacity - wit" , "French morale as in de corps?" , "Stripe (anag)" , "Lively wit" , "Vivaciousness" .)
