Article written by Proust (3)
I believe the answer is:
les
'article written by proust' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for les that I've seen before include "-- Dawson (late comedian)" , "-- Miserables, musical" , "French article; name" , "-- Dawson, English comic" , "Boy's name (abbr)" .)
