English

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).
