Getting up a revolt (6)
I believe the answer is:
rising
I believe this clue is a double definition.
'getting up' is the first definition.
('rise' can be a synonym of 'get up')
'a revolt' is the second definition.
(I know that revolt can be written as rising)
(Other definitions for rising that I've seen before include "Armed revolt against authority" , "Upwardly mobile" , "Revolt; coming up" , "Upward rebellion?" , "In the ascendant" .)
