Spirit, liveliness (6)
I believe the answer is:
esprit
I believe this is a double definition.
'spirit' is the first definition.
(I know that esprit is a type of spirit)
'liveliness' is the second definition.
(I know that esprit is a type of liveliness)
(Other definitions for esprit that I've seen before include "Liveliness of mind or spirit" , "Group morale is . . . . . . de corps" , "Stripe (anag)" , "Vivacious wit" , "Sparkling quality" .)
