Check credit rating that's out of place (5)
I believe the answer is:
audit
'check' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for audit that I've seen before include "Investigate" , "Financial check" , "Thoroughgoing check" , "Inspect accounts" , "review of books" .)
