Cobblers fitting sole in alcove (7)
I believe the answer is:
baloney
'cobblers' is the definition.
(I've seen this before)
'fitting sole in alcove' is the wordplay.
'fitting sole' becomes 'lone' (synonyms. I am not sure about the 'fitting' bit.).
'in' means one lot of letters goes inside another.
'alcove' becomes 'bay' (synonyms).
'lone' going into 'bay' is 'BALONEY'.
Can you help me to learn more?
(Other definitions for baloney that I've seen before include "Tripe < , smoked sausage" , "Tosh" , "rhubarb" , "foolish talk!" , "deceptive talk" .)
