May return something to eat (3)
I believe the answer is:
yam
'something to eat' is the definition.
(yam is a kind of food)
'may return' is the wordplay.
'return' says the letters should be written in reverse.
'may' reversed gives 'YAM'.
(Other definitions for yam that I've seen before include "Edible tuber" , "vegetable plant" , "Potato-like vegetable" , "May be a sweet spud" , "Tropical climber" .)
