Uphill revolt? (6)
I believe the answer is:
rising
This clue is a double definition.
'uphill' is the first definition.
(I know that uphill can be written as rising)
'revolt?' is the second definition.
(I know that revolt can be written as rising)
(Other definitions for rising that I've seen before include "Approaching the age of" , "Armed revolt against authority" , "Upwardly mobile" , "Sloping up; rebellion" , "working one's way up" .)
