  • US: /ˈsænɪˌtɛɹi/[1]

Etymology

Most dictionaries take it as borrowed from French sanitaire,[2][3][4][5][6][7][8] formed from Latin sānitās (“health”), from sānus (“healthy, sane”),[4][5][6][3] with the French suffix -aire.[3][8] The OED, revised in 2025, analyses it instead as the Latin noun with the English suffix -ary, modelled on the French word, which it dates to 1801;[9] Etymonline dates the French word to 1812.[4] The OED compares Spanish sanitario, Portuguese sanitário and Italian sanitario.[9] The Latin noun is the source of sanity, and its base of sane.[2][4]

Earliest recorded meaning

Relating to the conditions that affect health, especially cleanliness and the prevention of disease: 1816, in the Morning Chronicle.[9]

Semantic evolution

The word is a 19th-century one, linked from the start with public health and hygiene.[9][5] Other dictionaries date it later: Etymonline to 1823,[4] Merriam-Webster to 1838,[8] and Barnhart to 1842.[3] From 1847 it was applied to products made for hygiene, especially plumbing and bathroom fixtures; since 1863 it has also meant clean enough to keep the risk of disease low.[9] From 1880 it was used of products for menstruation;[9] Etymonline records sanitary towel by 1881 and sanitary napkin by 1885.[4] A sense "promoting health, health-giving" was used from 1825 to 1916 and is now obsolete.[9] Weekley, writing in 1921, observed that after its great vogue in the 19th century the word was being displaced by the more fashionable hygienic.[10]
