Get in RADA to become such a player? (9)
I believe the answer is:
tragedian
'such a player?' is the definition.
(tragedian is a kind of player)
'get in rada to become' is the wordplay.
'to become' indicates an anagram.
'get'+'in'+'rada'='getinrada'
'getinrada' with letters rearranged gives 'TRAGEDIAN'.
(Other definitions for tragedian that I've seen before include "Dramatist" , "Egad, I rant about dramatic actor" , "A great din (anag) - actor" , "Serious actor" , "actor in Macbeth?" .)
