"The Waste Land” writer (5)
I believe the answer is:
eliot
'the waste land writer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eliot that I've seen before include "Practical Cats author" , "One of two writers" , "T.S. --, poet" , "T.S. or George?" , "T S . . . . ., great poet of 'The Waste Land'" .)
