Morale (6)
I believe the answer is:
esprit
'morale' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for esprit that I've seen before include "Vivacity - wit" , "Vivacity, liveliness" , "Liveliness - priest (anag)" , "Vivacious wit" , "Liveliness of mind or spirit" .)
