Etymology
PIE word *h₂énti Borrowed from Middle French antipathie (“deep dislike; object of dislike; incompatibility between things”) (modern French antipathie (“dislike, antipathy”)), and from its etymon Latin antipathīa (“counteraction; natural aversion, antipathy”), from Ancient Greek ἀντῐπάθειᾰ (antĭpátheiă, “suffering instead”), Koine Greek ἀντῐπάθειᾰ (antĭpátheiă, “contrary affection; contrast; counteraction; opposition”), from ἀντῐπᾰθής (antĭpăthḗs, “(adjective) felt mutually; in return for suffering; (noun) remedy for suffering”) (from ἀντι- (anti-, prefix meaning ‘against’) + πᾰ́θος (pắthos, “death; disaster; misfortune; pain; suffering; strong feeling, emotion, passion, pathos”) (further etymology uncertain, possibly ultimately from Proto-Indo-European *bʰendʰ- (“to bind; a bond”) or *kʷendʰ- (“to endure; to suffer”)) + -ης (-ēs, suffix forming third-declension adjectives)) + -ειᾰ (-eiă, suffix forming feminine adjectives and nouns).
