New gold constituency accepted by government is disgusting (10)
I believe the answer is:
nauseating
'disgusting' is the definition.
(nauseating is a kind of disgusting)
'new gold constituency accepted by government' is the wordplay.
'new' becomes 'n' (abbreviation as in New Testament NT).
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'constituency' becomes 'seat' (House of Commons seats represent constituencies).
'accepted' becomes 'in' (I've seen this in other clues).
'by government' becomes 'g' (abbreviation for government. I am not sure about the 'by' bit.).
'n'+'au'+'seat'+'in'+'g'='NAUSEATING'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for nauseating that I've seen before include "Loathsome" , "being hard to keep down" , "Stomach-turning" , "Revolting" , "arousing unpleasant feeling" .)
