Others see his work as play (9)
I believe the answer is:
dramatist
'others see his work' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'play' is the wordplay.
I cannot quite understand how this works, but
'play' could be 'drama' (synonyms) and 'drama' is located in the answer.
This explanation may well be incorrect...
'as' acts as a link.
Can you help me to learn more?
(Other definitions for dramatist that I've seen before include "Shakespeare, say" , "O'Neill or O'Casey, for example" , "Coward perhaps" , "One who writes plays" , "Wordsmith" .)
