Actor that is serious at reading play (9)
I believe the answer is:
tragedian
'actor that is serious' is the definition.
'tragedian' can be an answer for 'actor' (tragedian is a kind of actor). I'm unsure of the rest of the definition.
'at reading play' is the wordplay.
'play' indicates anagramming the letters.
'at'+'reading'='atreading'
'atreading' anagrammed gives 'TRAGEDIAN'.
Can you help me to learn more?
(Other definitions for tragedian that I've seen before include "Serious actor" , "A great din (anag) - actor" , "Egad, I rant about actor in sad drama" , "actor in Macbeth?" , "Egad, I rant about dramatic actor" .)
