Goes for the lettuce? (6)
I believe the answer is:
leaves
'goes' is the definition.
(leaving is a kind of going)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for leaves that I've seen before include "Abandons" , "exits" , "Departs from the sheets" , "Departs with book pages?" , "takes off" .)
