Only in the bay does one find rubbish (7)
I believe the answer is:
baloney
'one find rubbish' is the definition.
'baloney' can be an answer for 'rubbish' (thesaurus). I'm unsure of the 'one find' bit.
'only in the bay' is the wordplay.
'only' becomes 'lone' (synonyms).
'in' indicates putting letters inside.
'lone' put inside 'bay' is 'BALONEY'.
'does' acts as a link.
Can you help me to learn more?
(Other definitions for baloney that I've seen before include "Nonsense; lean yob (anag)" , "foolish talk!" , "deceptive talk" , "Cobblers" , "Tripe < , smoked sausage" .)
