Energetic wit (6)
I believe the answer is:
esprit
'energetic wit' 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 "Sprightliness" , "... de corps, team spirit" , "French morale as in de corps?" , "Liveliness - priest (anag)" , "wit from France" .)
