In duck way to produce quack? (9)
I believe the answer is:
homeopath
'produce quack?' 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?
'in duck way' is the wordplay.
'in' becomes 'home' ('he's in' can mean 'he's home').
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'way' becomes 'path' (synonyms).
'home'+'o'+'path'='HOMEOPATH'
'to' is the link.
Can you help me to learn more?
(Other definitions for homeopath that I've seen before include "therapist" , "Quack perhaps" , "one offers treatment" , "he treats you, naturally" , "Health practitioner" .)
