Incline, slope (4)
I believe the answer is:
hill
I believe this is a double definition.
'incline' is the first definition.
(inclined land)
'slope' is the second definition.
(sloped area of land)
(Other definitions for hill that I've seen before include "Over the .... - past life's prime" , "Mound (of mole, ants)" , "Elevation on land" , "Mount" , "Raised area of land" .)
