Our, in Arles (5)
I believe the answer is:
notre
'our in arles' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for notre that I've seen before include ". . . . . Dame is a great cathedral in Paris" , "French novel 'The Hunchback of ..... Dame'" , "Victor Hugo wrote'The Hunchback of ..... Dame'" .)
