Crooked; inclination (4)
I believe the answer is:
bent
I believe this is a double definition.
'crooked' is the first definition.
(similar in meaning)
'inclination' is the second definition.
(I know that bent is a type of inclination)
(Other definitions for bent that I've seen before include "Warped" , "Flexed -- penchant" , "Angled or curved" , "Determined - sounds crooked" , "on the fiddle" .)
