Leant (8)
I believe the answer is:
inclined
'leant' is the definition.
('incline' can be a synonym of 'lean')
This is the entire clue.
(Other definitions for inclined that I've seen before include "Disposed or leaned" , "Predisposed or leaning towards" , "Sloping - likely" , "Running down" , "Disposed; sloping" .)
