Maiden in RADA performing emotional episode (5)
I believe the answer is:
drama
'emotional episode' is the definition.
(I've seen this before)
'maiden in rada performing' is the wordplay.
'maiden' becomes 'm' (cricket abbreviation).
'in' means one lot of letters goes inside another.
'performing' indicates anagramming the letters.
'rada' is an anagram of 'draa'.
'm' inserted inside 'draa' is 'DRAMA'.
(Other definitions for drama that I've seen before include "theatre performance" , "Literary genre for the stage" , "Theatrical performance" , "Highly emotional episode" , "Play - big emotional scene" .)
