Wound from rabbit even! (4)
I believe the answer is:
bite
'wound' is the definition.
(bite is a kind of wound)
'from rabbit even' is the wordplay.
'from' indicates the answer is hidden within the clue.
'BITE' can be found hidden inside 'rabbit even'.
(Other definitions for bite that I've seen before include "Cut with the teeth" , "Injury from teeth" , "Small amount to eat" , "Use one's teeth" , "Mouthful" .)
