I would turn more quiet as a drinks supplier (9)
I believe the answer is:
distiller
'a drinks supplier' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'i would turn more quiet' is the wordplay.
'i would' becomes 'I'd'.
'turn' shows that the letters should be reversed in order.
'more quiet' becomes 'stiller' ('still' can be a synonym of 'quiet').
'id' back-to-front is 'di'.
'di'+'stiller'='DISTILLER'
'as' is the link.
Can you help me to learn more?
(Other definitions for distiller that I've seen before include "One producing alcohol" , "Producer of spirits" , "Eg, whisky producer" , "Drinks producer" , "Spirits manufacturer" .)
