Forms

sanitário (feminine sanitária, masculine plural sanitários, feminine plural sanitárias)[1]

Etymology

It is borrowed from French sanitaire, adapted with the suffix -ário and first recorded in 1844.[2][1][3][4] Houaiss analyses it as a Latin stem with the same suffix and compares the French word, which he dates to 1801.[5] Vieira also took it from French.[6] The DLP and Michaelis derive it directly from Latin sānitās (“health”) with the suffix.[7][8] Michaelis notes the loss of a syllable.[8]

The French word is a learned formation from the Latin noun with -aire.[1] The Latin noun is from sānus (“healthy”) with the suffix -tās.[9] The Portuguese outcome of the Latin noun is sanidade.[1]

Earliest recorded meaning

The record of 1844 is an adjective, “relating to health”.[2][5] Vieira's dictionary defines it in 1873 as “concerning the preservation of public health”, with leis, medidas and precauções sanitárias and the cordão sanitário, a line of troops that cuts off a country struck by a contagious disease.[6]

Semantic evolution

From public health the adjective passed to the bathroom and its fittings (louça sanitária, vaso sanitário).[5][4] In Brazil the noun means the toilet bowl, short for vaso sanitário, and by metonymy the room or public place with toilets.[5][4] Modern compounds include aterro sanitário “sanitary landfill”.[1]
