sanitation

Etymology

It is formed from English sanitary + -ation, irregularly, from the stem of the adjective.^{[2][3][4][5][6]} Sanitary was made after French sanitaire (“of public health and hygiene”) from Latin sānitās (“health”),^[2] which comes from sānus (“healthy”).^[5][7] Klein instead derived it from sanity with the suffix -ation.^[8]

Earliest recorded meaning

The activity of securing sanitary conditions and public health: 1826, in a work by W. Richmond addressed to shipping, agriculture and commerce,^[2] where, according to Wilton, it refers to quarantining ships before they entered a port.^[7] Most dictionaries give 1848 as the first date.^[5][6][9]

Semantic evolution

Like sanitary, the word first concerned health and the control of disease, and its meaning later narrowed to cleanliness, the removal of refuse and sewerage.^[7] Etymonline defines the 1848 sense as the practical and scientific methods of preserving health.^[5] Its somewhat euphemistic use for the removal of garbage and household waste is recorded by 1916, in sanitation man,^[5] and Barnhart dates compounds such as sanitation worker, sanitation truck and sanitation department, coined as euphemisms in American English, to 1939.^[6][10] The Shorter Oxford also records the sense "toilet facilities".^[3] In ecology Merriam-Webster records a further sense: the keeping of a wild population healthy by predators that remove its weak members.^[9]
