Survived (6)
I believe the answer is:
lasted
'survived' is the definition.
('last' can be a synonym of 'survive')
This is all the clue.
(Other definitions for lasted that I've seen before include "Kept going" , "Continued, being salted" , "Persisted, endured" , "Continued for some time, endured" , "Endured, survived" .)
