Breadwinner with listener beside north-east river (6)
I believe the answer is:
earner
'breadwinner' is the definition.
(I've seen this before)
'listener beside north-east river' is the wordplay.
'listener' becomes 'ear' (body part which hears or listens).
'beside' is a charade indicator (letters next to each other) (I've seen this in other clues).
'north east' becomes 'ne'.
'river' becomes 'r' (abbreviation for river).
'ear'+'ne'+'r'='EARNER'
'with' is the link.
(Other definitions for earner that I've seen before include "Coin collector" , "Something making a good profit (colloq.)" , "Worker with income" , "One in employment" , "Money-making activity" .)
