KanjiJLPT N1
Partial

partial, side, left-side radical, inclining, biased

Mnemonic

Butler Alfred is partial to one particular hen in the coop—he sneaks her extra grain every morning while the other birds get nothing. Alfred's bias is legendary; the hen struts around like royalty, knowing the butler always takes her side over every other animal.
Additional thoughts
Picture Alfred in his formal suit crouching in a chicken coop, hand-feeding one spoiled hen while dozens of jealous birds cluck angrily. The image of a dignified butler playing favorites with poultry is absurd enough to stick.
Quick recall
Butler Alfred plays favorites, being partial to one spoiled hen over all others.
