Styled in a fashion imitated, on the quiet (6)
I believe the answer is:
shaped
'styled in a fashion' is the definition.
I can't tell whether this definition defines the answer.
'imitated on the quiet' is the wordplay.
'imitated' becomes 'aped' ('ape' can be a synonym of 'imitate').
'on' means one lot of letters go next to another.
'the quiet' becomes 'sh'.
'aped' after 'sh' is 'SHAPED'.
Can you help me to learn more?
(Other definitions for shaped that I've seen before include "Cast or moulded" , "modelled" , "Formed or fashioned" , "Given a certain form - phased accordingly" , "Formed - moulded" .)
