Something to eat, little one (6)
I believe the answer is:
shrimp
'something to eat' is the definition.
(shrimp is a kind of food)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for shrimp that I've seen before include "little fellow" , "Small prawn-like creature" , "very small one" , "colour?" , "Small edible crustacean" .)
