Dining room repeatedly gutted more seabass (4)
I believe the answer is:
mess
'dining room' is the definition.
(I know that mess is a type of dining room)
'repeatedly gutted more seabass' is the wordplay.
I cannot really see how this works, but
'more' could be 'm' and 'm' is found within the answer.
The remaining letters 'ess' 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 mess that I've seen before include "Jumble" , "Where one might eat" , "hash" , "Canteen - chaos" , "pap" .)
