"The Cocktail Party” playwright (5)
I believe the answer is:
eliot
'the cocktail party playwright' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eliot that I've seen before include "T.S. or George?" , "The Waste Land author" , "T S . . . . ., great poet of 'The Waste Land'" , "George - - (novelist)" , "Practical Cats author" .)
