Slope, slant (7)
I believe the answer is:
incline
I believe this is a double definition.
'slope' is the first definition.
(I know that slope can be written as incline)
'slant' is the second definition.
(I know that incline is a more specific form of slant)
(Other definitions for incline that I've seen before include "lean forward" , "Lean, slope" , "prejudice" , "Tend; lean" , "Turn" .)
