Endure final (4)
I believe the answer is:
last
I believe this clue is a double definition.
'endure' is the first definition.
(I know that endure can be written as last)
'final' is the second definition.

(Other definitions for last that I've seen before include "Final; keep going" , "model of repair" , "Bringing up the rear" , "Continue" , "nowhere near winning Miss World?" .)
