Writer of plays: mark as completed for audience (7)
I believe the answer is:
chekhov
This might be a double definition.
'writer of plays' is the first definition.
The definition suggests a singular noun which matches the answer.
'as completed for audience' is the second definition.
The definition suggests a singular noun which matches the answer.
'mark' acts as a link.
Can you help me to learn more?
(Other definitions for chekhov that I've seen before include "Anton ---, Russ. author" , "playwright" , "Anton -, dramatist (The Cherry Orchard)" , "Writer of "The Cherry Orchard"" , "Author of "Uncle Vanya"" .)
