"Lost in Yonkers" playwright (5)
I believe the answer is:
simon
'lost in yonkers playwright' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for simon that I've seen before include "- Templar, The Saint" , "disciple" , "Sir -- Rattle, conductor" , "Man's name" , "A simple character in nursery rhyme" .)
