Little bounder devoid of ecstasy and elation (3)
I believe the answer is:
joy
'elation' is the definition.
(I've seen this before)
'little bounder devoid of ecstasy' is the wordplay.
'little bounder' becomes 'joey' (little kangaroo - animal that bounds).
'devoid of' indicates named letters should be taken away.
'ecstasy' becomes 'E' (informal term for the drug).
'joey' with 'e' removed is 'JOY'.
'and' acts as a link.
(Other definitions for joy that I've seen before include "Elation" , "Delight" , "Intense gladness" , "Subject of 11 [ODE]" , "Great happiness" .)
