hygiene

Etymology

It is borrowed from French hygiène,^[2][3][4][5] and partly New Latin hygieina,^[2][5][6] from Ancient Greek ὑγιεινή (hugieinḗ), short for ὑγιεινὴ τέχνη (hugieinḗ tékhnē, “the healthful art”),^[3][4][6] the feminine of ὑγιεινός (hugieinós, “healthful”),^[6][7] from ὑγιής (hugiḗs, “healthy, sound”).^[3][8][9] In French the word is found in the 16th century as hygiaine in Ambroise Paré, and in the Académie's dictionary in 1762.^[2] Aristotle had used the Greek adjective as a noun meaning "health".^[3][8] Barnhart's full edition, Klein and Hoad explain hugiḗs as "living well", from a prefix meaning "well" and a root meaning "to live",^[10][8][11] whereas Etymonline and the American Heritage Dictionary connect it with the root Proto-Indo-European *aiw- (“vital force, life”).^[3][6] Etymonline describes the awkward English spelling as a relic of the struggle to render the Greek vowels in French.^[3]

Earliest recorded meaning

The branch of knowledge concerned with keeping healthy: the Shorter Oxford dates the word to the late 16th century, when it was used in its Latin and Greek forms,^[12][13] and Dictionary.com gives 1590–1600.^[14] Barnhart and Merriam-Webster date hygiene to 1671 and Etymonline to the 1670s,^[4][5][3] while the OED's first quotation, in an entry not revised since 1899, is from 1799, in Robert Southey's Letters from Spain.^[2] Hoad gives the 19th century.^[11]

Semantic evolution

The OED's definition is the knowledge or practice of maintaining health, and a system of rules for it, including sanitary science.^[2] From the science the word passed to the conditions and practices that keep people healthy,^[5][12] and above all to cleanliness, as in personal hygiene.^[15] Collins now records a further extension to practices that keep any environment safe and secure, such as computer systems.^[15] The adjective hygienic followed in 1833.^[4]
