Swivelled rear end for a show (6)
I believe the answer is:
render
'swivelled rear end for a show' is the definition.
I can't judge whether this defines the answer.
'rear end for a show' is the wordplay.
'rear' becomes 'r' (this could be a standard abbreviation of which I'm unaware).
'for' is a charade indicator (letters next to each other).
'a show' becomes 'ER' (US medical drama).
'r'+'end'+'er'='RENDER'
Can you help me to learn more?
(Other definitions for render that I've seen before include "Depict artistically" , "Provide (help), plaster" , "Hand over; plaster" , "Melt fat or perform song" , "Give performance or melt down fat" .)
