Free marketeer to retain product in the majority of cases (10)
I believe the answer is:
monetarist
'free marketeer' is the definition.
The definition suggests a singular noun which matches the answer.
'retain product in the majority of cases' is the wordplay.
I cannot quite see how this works, but
an anagram of 'retain' is 'netari' which is present in the answer.
'product' could be 'os' (OS is an example) and 'os' is present in the remaining letters.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
A single letter 'm' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for monetarist that I've seen before include "Finance expert" , "Advocate of controlling the supply of financial resources" , "economic expert" , "Economic theorist" .)
