Incline, rise (6)
I believe the answer is:
ascent
I believe this clue is a double definition.
'incline' is the first definition.
(I know that ascent is a type of incline)
'rise' is the second definition.
(I know that rise can be written as ascent)
(Other definitions for ascent that I've seen before include "Uphill journey" , "A climb or way up" , "advancement" , "progress" , "lift" .)
