Fish half cut, still eating one (7)
I believe the answer is:
halibut
'fish' is the definition.
(I know that halibut is a type of fish)
'half cut still eating one' is the wordplay.
I cannot quite see how this works, but
'still' could be 'but' (I've seen this in other clues) and 'but' is located in the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
The remaining letters 'hal' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for halibut that I've seen before include "Utah lib (anag)" , "Swimmer" , "Marine food fish" , "Largest flatfish" , "Large food fish" .)
