Extra cash for something to eat (5)
I believe the answer is:
morel
'something to eat' is the definition.
I can't tell whether this defines the answer.
'extra cash' is the wordplay.
'extra' becomes 'more' (both can mean additional).
'cash' becomes 'L' (The pound sterling symbol is an elaborate L).
'more'+'l'='MOREL'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for morel that I've seen before include "Edible fungus" , "Edible mushroom" , "One has a cap" , "Type of mushroom" .)
