Sense rage damaged enthusiasm (9)
I believe the answer is:
eagerness
'enthusiasm' is the definition.
(eagerness is a kind of enthusiasm)
'sense rage damaged' is the wordplay.
'damaged' indicates anagramming the letters.
'sense'+'rage'='senserage'
'senserage' anagrammed gives 'EAGERNESS'.
(Other definitions for eagerness that I've seen before include "Keen attitude" , "Keenness, enthusiasm" , "'Keenness, avidness (9)'" , "Sense rage (anag.)" , "Avidity" .)
