E.g. penny for the guy -- that's long-established easy profit (5,3,3,4)
I believe the answer is:
money for old rope
'easy profit' is the definition.
(I've seen this before)
'e g penny for the guy that's long-established' is the wordplay.
I cannot quite understand how this works, but
'e' is within the answer.
'g' could be 'm' (synonyms) and 'm' is found in the answer.
'penny' could be 'p' (short for pence) and 'p' is present in the answer.
'long' could be 'l' and 'l' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for money for old rope that I've seen before include "Reward for little effort" , "dealing with elderly guys?" , "Easy profit" , "as made by oakum pickers?" , "A piece of cake" .)
