Begrudging feeling (4)
I believe the answer is:
envy
'begrudging feeling' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for envy that I've seen before include "Be green" , "Resentful longing" , "The green-eyed emotion" , "Wish for thing or quality belonging to another" , "Jealousy, begrudgery" .)
