There you are (5)
I believe the answer is:
voila
'there you are' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for voila that I've seen before include "There you go!" , "See there, howzat - in France" , "See there, behold - in France" , "Announcement from French producer" , "The French see" .)
