Strong inclination or liking (8)
I believe the answer is:
penchant
I believe this is a double definition.
'strong inclination' is the first definition.
(I've seen this before)
'liking' is the second definition.
(I know that penchant is a type of liking)
(Other definitions for penchant that I've seen before include "Partiality" , "Disposition" , "Inclination, bent" , "Leaning towards or liking for" , "Fondness (for) - bias (towards)" .)
