Inclination, tendency (7)
I believe the answer is:
leaning
I believe this clue is a double definition.
'inclination' is the first definition.
(incline can mean to lean)
'tendency' is the second definition.
(I know that tendency can be written as leaning)
(Other definitions for leaning that I've seen before include "Inclining, bending" , "Sloping" , "Inclination" , "Inclining, slanting" , "Tendency, partiality" .)
