Its a mistake to be led astray over gold (5)
I believe the answer is:
error
'gold' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'its a mistake to be led astray over' is the wordplay.
I cannot quite understand how this works, but
'mistake' could be 'err' (to err is to make a mistake or blunder) and 'err' is found within the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is located in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for error that I've seen before include "Solecism" , "Gaffe" , "Boob" , "Faulty judgment" , "Mistake, lapse" .)
