Endure or survive (6)
I believe the answer is:
remain
This clue is a double definition.
'endure' is the first definition.
(I've seen this in another clue)
'survive' is the second definition.

(Other definitions for remain that I've seen before include "stop behind?" , "Continue in position" , "Stay, don't go" , "Old dance" , "Stay on after others have gone" .)
