Inclination to show prejudice? (4)
I believe the answer is:
bias
This clue is a double definition.
'inclination' is the first definition.
(I know that bias is a type of partiality)
'prejudice?' is the second definition.
(I know that prejudice can be written as bias)
'to show' acts as a link.
(Other definitions for bias that I've seen before include "One-sided prejudice" , "Large city in Florida" , "could be binding" , "(Bowls) irregular shape" , "Prejudice, one-sidedness" .)
