Arles article (3)
I believe the answer is:
les
'arles article' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for les that I've seen before include "- Dawson, Br. comedian" , "Boy's name (abbr)" , "French definite article" , "French article; name" , "-- Miserables, musical" .)
