Very good to receive money for something that is breathtaking (4)
I believe the answer is:
smog
'for something that is breathtaking' is the definition.
The definition suggests a singular noun which matches the answer.
'very good to receive money' is the wordplay.
'very' becomes 'so' (both can mean 'extremely').
'good' becomes 'g' (abbreviation).
'to receive' is an insertion indicator.
'money' becomes 'm' (abbreviation used in economics).
'so'+'g'='sog'
'sog' enclosing 'm' is 'SMOG'.
Can you help me to learn more?
(Other definitions for smog that I've seen before include "Fog polluted by smoke" , "Visible air pollution" , "Pollution haze/fog" , "Bad visibility caused by emissions from chimneys" , "Pollution fog" .)
