Records verified in duet aid fix-up (7)
I believe the answer is:
audited
'records verified' is the definition.
I can't judge whether this definition defines the answer.
'duet aid fix-up' is the wordplay.
'duet aid' can be anagrammed to 'AUDITED'.
But, I am unsure how this is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for audited that I've seen before include "Checked books" , "not cooked?" , "Checked (someone's accounts)" , "officially checked" , "Examined (accounts)" .)
