Card trick taking in broadcasters, say (8)
I believe the answer is:
comedian
'card' is the definition.
(thesaurus)
'trick taking in broadcasters say' is the wordplay.
'trick' becomes 'con' (a con is a fraud or trick).
'taking in' means one lot of letters goes inside another.
'broadcasters say' becomes 'media' (broadcasters are part of the media).
'con' enclosing 'media' is 'COMEDIAN'.
(Other definitions for comedian that I've seen before include "Demoniac kind of funny man" , "Humorous entertainer" , "I'm not taken seriously" , "Stand-up" , "Demoniac sort of funny man" .)
