Last bear (6)
I believe this clue is a double definition.
'last' is the first definition.
(I know that last can be written as endure)
'bear' is the second definition.
(both can mean to tolerate)
(Other definitions for endure that I've seen before include "Bear, stick it out" , "Bear without giving up" , "Put up with - last" , "Undergo a tough time" , "Stand" .)
(Other definitions for abide that I've seen before include "'. . . . . with me, fast falls the eventide'" , "Remain - tolerate" , "lodge" , "Stay or endure" , "Live, dwell (archaic)" .)
