Experienced type, true pro theatrically (7)
I believe the answer is:
trouper
This clue could be a double definition.
'experienced type' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'true pro theatrically' is the second definition.
I can't judge whether this definition defines the answer.
Can you help me to learn more?
(Other definitions for trouper that I've seen before include "Travelling performer" , "reliable worker" , "Loyal, hard-working type" , "Very reliable performer" , "Old stager" .)
