Angle, tilt (5)
I believe the answer is:
slant
I believe this clue is a double definition.
'angle' is the first definition.
(I know that angle can be written as slant)
'tilt' is the second definition.
(I know that tilt can be written as slant)
(Other definitions for slant that I've seen before include "passing breeze?" , "Point of view; slope" , "Viewpoint; slope" , "Deviation from the horizontal" , "Angle; incline" .)
