Fish and wedges hospital binned (4)
I believe the answer is:
eels
'fish' is the definition.
(eel is a type of fish)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for eels that I've seen before include "Feels small imprisoning water creatures" , "Slender fishes" , "Snakes wriggling in lees" , "Long thin fish" , "Lengthy fish" .)
