Cobblers lacking companions to stop by (7)
I believe the answer is:
baloney
'cobblers' is the definition.
(I've seen this before)
'lacking companions to stop by' is the wordplay.
'lacking companions' becomes 'alone' (I can't justify this - if you can you should give a lot more credence to this answer).
'to stop' is an insertion indicator (stopping can mean blocking a gap).
'alone' placed inside 'by' is 'BALONEY'.
Can you help me to learn more?
(Other definitions for baloney that I've seen before include "rhubarb" , "Tosh" , "Tripe < , smoked sausage" , "foolish talk!" , "Cobblers" .)
