A rake's inclination? (5)
I believe the answer is:
slant
I believe this is a double definition.
'a rake's' is the first definition.
('slant' can be a synonym of 'rake')
'inclination?' is the second definition.
(slant is a kind of inclination)
(Other definitions for slant that I've seen before include "Lean, point of view" , "Lie obliquely" , "It's at an angle to the horizontal" , "Slope, lean" , "Angle; slope" .)
