Leaves mum drinking half of pina colada (7)
I believe the answer is:
spinach
'leaves' is the definition.
(leafy vegetable)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for spinach that I've seen before include "Popeye the Sailor's favourite vegetable" , "something to eat" , "leaves on plate?" , "Popeye's strength-giver" , "Popeye the Sailor's vegetable of choice" .)
