Make last (3,3)
I believe the answer is:
eke out
'make last' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for eke out that I've seen before include "Make last, use sparingly" , "Make stretch" , "Just about manage to make a living" , "Make last like scarce resources" , "Make it last, like a resource" .)
