Performer in part is televised (7)
I believe the answer is:
artiste
'performer' is the definition.
(artiste is a kind of performer)
'in part is televised' is the wordplay.
'in' says the answer is hidden in the clue.
'ARTISTE' is hidden within 'part is televised'.
(Other definitions for artiste that I've seen before include "Attires like entertainer" , "Attires (anag.)" , "One entertaining" , "Professional performer" , "Player" .)
