Doing well in town, following the crowd (10)
I believe the answer is:
conformity
'the crowd' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'doing well in town' is the wordplay.
'doing well' becomes 'on form' (someone on form is performing at a good standard).
'in' means one lot of letters goes inside another.
'town' becomes 'city' (city is a type of town).
'onform' placed into 'city' is 'CONFORMITY'.
'following' is the link.
Can you help me to learn more?
(Another definition for conformity that I've seen is " Acceptance of general standards".)
