Young hares (8)
I believe the answer is:
leverets
'young hares' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for leverets that I've seen before include "Set elver to get young hares" , "Let verse envisage young hares" , "small creatures" , "big-eared youngsters" , "Set elver among young hares" .)
