Poet Guest (5)
I believe the answer is:
edgar
'poet guest' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for edgar that I've seen before include "... Allan Poe, author" , "character in King Lear" , "Part of 1 25 [KING LEAR]" , "Earl's son" , "- Wallace, Eng. thriller writer" .)
