Sophisticated playwright is said to be uncultivated (5)
I believe the answer is:
wilde
'sophisticated playwright' is the definition.
'wilde' can be an answer for 'playwright' (I've seen this before). I'm not certain of the 'sophisticated' bit.
'said to be uncultivated' is the wordplay.
'said' becomes 'e' (I can't justify this - if you can you should give a lot more credence to this answer).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'be uncultivated' becomes 'wild' (I've seen this in another clue).
'e' put after 'wild' is 'WILDE'.
'is' is the link.
Can you help me to learn more?
(Other definitions for wilde that I've seen before include "Author of Lady Windermere's Fan" , "Irish wit and playwright" , "Author of The Picture of Dorian Gray" , "Oscar, great Irish writer" , "Author of The Portrait of Dorian Gray" .)
