Believe sailor is to get assessment for a loan (6,6)
I believe the answer is:
credit rating
'to get assessment for a loan' is the definition.
I can't tell whether this defines the answer.
'believe sailor' is the wordplay.
'believe' becomes 'credit' (I've seen this in another clue).
'sailor' becomes 'rating' (British term for a naval enlisted man).
'credit'+'rating'='CREDIT RATING'
'is' is the link.
Can you help me to learn more?
(Other definitions for credit rating that I've seen before include "Trust able seaman" , "Estimate of person's financial trustworthiness" , "justification for advance" , "loan may depend on it" , "lender's assessment" .)
