Very little élan (4)
I believe the answer is:
dash
This clue is a double definition.
'very little' is the first definition.
'elan' is the second definition.
(both can mean energy)
(Other definitions for dash that I've seen before include "gratuity" , "Hurry ("must ____!")" , "Go quickly" , "Run hurriedly; hyphen" , "Stroke < > to frustrate" .)
