Fighter in ring turning to drama (7)
I believe the answer is:
matador
'fighter in ring' is the definition.
'matador' can be an answer for 'fighter' (matador is a kind of fighter). I am not sure about the 'in ring' bit.
'turning to drama' is the wordplay.
'turning' is an anagram indicator.
'to'+'drama'='todrama'
'todrama' anagrammed gives 'MATADOR'.
Can you help me to learn more?
(Other definitions for matador that I've seen before include "The one who kills the bull" , "Ring butcher" , "Spaniard that fights" , "fighter in the ring?" , "he aims to get a bull" .)
