No fish can make a foul noise! (4)
I believe the answer is:
fowl
'no fish' is the definition.
The definition and answer can be both animals as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'a foul noise' is the wordplay.
'noise' shows a homophone (sound like).
'foul' is a homophone of 'FOWL'.
'can make' is the link.
Can you help me to learn more?
(Other definitions for fowl that I've seen before include "eg Chicken" , "Bird to be eaten or hunted as game" , "Any farmyard bird" , "Poultry bird" , "Domesticated bird" .)
