Pleat; food (4)
I believe the answer is:
tuck
This clue is a double definition.
'pleat' is the first definition.
(I know that tuck is a type of pleat)
'food' is the second definition.
(I've seen this before)
(Other definitions for tuck that I've seen before include "Position for diving" , "Friar friend of Robin Hood - to gather - food" , "Food for schoolboys" , "stuff" , "Cosmetic procedure" .)
