Overstuffs (5)
I believe the answer is:
sates
'overstuffs' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sates that I've seen before include "Fills with food, stuffs" , "Fully satisfies" , "Stuffs or cloys with excess" , "Fills to satisfaction" , "Gluts or cloys with excess" .)
