Cash exchanged in pure monetary transaction (8)
I believe the answer is:
purchase
'monetary transaction' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'cash exchanged in pure' is the wordplay.
'exchanged' indicates an anagram.
'in' indicates putting letters inside.
'cash' with letters rearranged gives 'chas'.
'chas' put into 'pure' is 'PURCHASE'.
Can you help me to learn more?
(Other definitions for purchase that I've seen before include "that has gone through the barcode reader?" , "Pay money" , "Leverage" , "become an owner" , "secure an advantage" .)
