A writing 'Oscar' (5)
I believe the answer is:
wilde
This clue could be a double definition.
'a writing' is the first definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'oscar' is the second definition.
(playwright Oscar Wilde)
Can you help me to learn more?
(Other definitions for wilde that I've seen before include "Author of Lady Windermere's Fan" , "Author of The Portrait of Dorian Gray" , "Irish wit and playwright" , "Author of The Picture of Dorian Gray" , "Oscar, great Irish writer" .)
