Out-dated (5)
I believe the answer is:
passe
I believe this is a double definition.
'out' is the first definition.
(I've seen this before)
'dated' is the second definition.
(I've seen this before)
(Other definitions for passe that I've seen before include "Jaded" , "Out-of-date (French)" , "Old hat" , "Past its prime - in France" , "Out of date" .)
