Endure the final one (4)
I believe the answer is:
last
This clue might be a double definition.
'endure' is the first definition.
(I know that endure can be written as last)
'final one' is the second definition.
The answer and definition can be both quantities as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'the' is the link.
Can you help me to learn more?
(Other definitions for last that I've seen before include "Final; endure" , "` `The cobler should stick to his ....' '" , "Shoemaker's shape" , "Hold out" , "Survive; after all others" .)
