What coiner produces — good simoleon in counterfeit form (9)
I believe the answer is:
neologism
'counterfeit form' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'what coiner produces good simoleon' is the wordplay.
I cannot really understand how this works, but
'good' could be 'g' (abbreviation) and 'g' is located in the answer.
an anagram of 'simoleon' is 'neoloism' which is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for neologism that I've seen before include "Newly-coined word or expression" , "New word or phrase" , "Brexit maybe" , "new term" , "Newly coined word" .)
