hypocorism

Etymology

Borrowed from Late Latin hypocorisma, a loan from Ancient Greek ὑποκόρισμα (hupokórisma), ὑποκορισμός (hupokorismós, “pet name”), from ὑποκορίζεσθαι (hupokorízesthai), ὑποκορίζομαι (hupokorízomai, “to use a pet name; to act in a childish manner”), from ῠ̔πο- (hŭpo-, prefix indicating a small degree) + κορίζομαι (korízomai, “to caress”) (from κόρος (kóros, “boy; youth”), κόρη (kórē, “girl; young woman”)).
