Surrealist 1D first to finish vegetable (4)
I believe the answer is:
'vegetable' is the definition.
(I know that leek is a type of vegetable)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for leek that I've seen before include "Vegetable symbol of Wales" , "Vegetable of the onion family" , "Plant; Welsh emblem" , "Vegetable emblem of Wales" , "Vegetable associated with Wales" .)
