Turning over stylish reading (9)
I believe the answer is:
inversion
'turning over' is the definition.
(I've seen this before)
'stylish reading' is the wordplay.
'stylish' becomes 'in'.
'reading' becomes 'version' (a reading can be an interpretation or version).
'in'+'version'='INVERSION'
(Other definitions for inversion that I've seen before include "upsetting change" , "The opposite of" , "turning around" .)
