Fishy character shed clothes jumping bail (7)
I believe the answer is:
halibut
'fishy character' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'shed clothes jumping bail' is the wordplay.
'shed' becomes 'hut' (I've seen this before).
'clothes' indicates putting letters inside.
'jumping' indicates an anagram.
'bail' with letters rearranged gives 'alib'.
'hut' enclosing 'alib' is 'HALIBUT'.
Can you help me to learn more?
(Other definitions for halibut that I've seen before include "Utah lib (anag)" , "Fish found in Bali hut" , "Large edible flatfish" , "Large food fish" , "Something fishy here" .)
