Source of pricy information for a swimmer in the nude (7)
I believe the answer is:
barcode
'source of pricy information for a' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'swimmer in the nude' is the wordplay.
I cannot really understand how this works, but
'swimmer' could be 'cod' (cod is a kind of fish) and 'cod' is found in the answer.
'nude' could be 'bare' (I've seen this before) and 'bare' is found in the remaining letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for barcode that I've seen is " may be scanned".)
