Definition
'Antipathetical' is the adjective form of 'antipathy,' meaning something that causes a feeling of strong dislike or opposition. It describes things that are fundamentally opposed or incompatible. Think of ideas that clash violently, or personalities that are diametrically different. It signifies a deep-seated aversion or repugnance. It's stronger than simply 'different'; it implies active opposition. An action may be antipathetical to one's beliefs, or a lifestyle to one's values. Unlike indifference, something antipathetical provokes a strong negative reaction. Ultimately, 'antipathetical' describes things inherently opposed to one another.
