Swallow greedily (7)
I believe the answer is:
engorge
'swallow greedily' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for engorge that I've seen before include "Eat ravenously" , "Eat immodestly" , "Overeat" , "Swell with blood, water, etc" , "Guzzle" .)
