Indignation after making the first daughter good bait for those down here (7)
I believe the answer is:
gudgeon
'indignation after making the first daughter good bait for those down here' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
This is all the clue.
Can you help me to learn more?
(Other definitions for gudgeon that I've seen before include "Swimmer" , "Small freshwater fish" , "angler's bait" , "Small carp-like fish" , "Fish, or person easily cheated" .)
