hygienic

Etymology

It is formed from English hygiene + -ic,^[2][3] and the OED compares the French adjective, recorded from 1812.^[2] In the view of Etymonline it is instead borrowed from French hygiénique, from hygiène;^[4] Merriam-Webster Unabridged calls the French origin probable.^[5] Hygiene is from the French noun, from Ancient Greek ὑγιεινή (hugieinḗ) (with τέχνη (tékhnē, “art”) understood), the feminine of ὑγιεινός (hugieinós, “healthful”), from ὑγιής (hugiḗs, “healthy”).^[2] Etymonline traces the Greek adjective to Proto-Indo-European *aiw- (“vital force, life”).^[4]

Earliest recorded meaning

Relating to hygiene: 1815 in Etymonline,^[4] 1833 in the OED, from Dunglison's Dictionary of Medical Science.^[2][5] The earlier English adjective was hygienal, from the 1660s.^[4]

Semantic evolution

The word first belonged to medical writing about the rules for keeping healthy, then came to describe whatever is clean and sanitary in itself, as in hygienic conditions.^[2][5] The variant hygienical is recorded from 1872,^[6] and the noun hygienics from 1836.^[4] Merriam-Webster's Collegiate also records a figurative use for something sterile and lacking warmth or vitality, like antiseptic.^[7]
