Hygiene
First proven use of the word in English was in 1677s. The word hygiene comes from the French word hygiène, which is the western version of Greek word ὑγιεινή (τέχνη) - hugieinē technē, meaning "(art) of health", from ὑγιεινός (hugieinos), "good for the health, healthy",  in turn from ὑγιής (hugiēs), "healthful, sound, salutary, wholesome". In ancient Greek religion, Hygeia (Ὑγίεια) was the daughter of Asclepius and represented health.
