Ancient; obsolete (7)
I believe the answer is:
archaic
I believe this clue is a double definition.
'ancient' is the first definition.
(I've seen this before)
'obsolete' is the second definition.
(I know that obsolete can be written as archaic)
(Other definitions for archaic that I've seen before include "Belonging to former times like some words" , "Behind the times" , "Belonging to former or ancient times" , "Antiquarian" , "From the past" .)
