English[edit]

Etymology[edit]

From Middle English, from Old French qualité, from Latin qualitatem, accusative of qualitas, from qualis (“of what kind”), from Proto-Indo-European *kʷo- (“who, how”). Cicero coined qualitas as a calque to translate the Ancient Greek word ποιότης (poiótēs, “quality”), coined by Plato from ποῖος (poîos, “of what nature, of what kind”).
