fossa f (plural fossas)[1]

Etymology

It is inherited from Latin fossa (“ditch, trench”), a noun from the feminine past participle of fodiō (“to dig”), with terra (“earth”) understood.[2][3][1] Houaiss's first date, 1124, comes from Machado.[2]

The same Latin word is Spanish huesa “grave”, Italian fossa, French fosse, Catalan fossa and Romanian foasă.[4][5] The Spanish fosa is a learned word, recorded from 1542.[2][6]

The Latin verb is from Proto-Italic *foþ-i-, from a root meaning “to poke, dig”, with cognates in Hittite, Baltic and Slavic.[7] Wiktionary gives the root as Proto-Indo-European *bʰedʰh₂-.[1]

Earliest recorded meaning

The oldest Portuguese sense is “grave”: in the Cantigas de Santa Maria God makes someone rise again from the fossa, and the Crónica Geral speaks of a time of famine when the squares were full of graves and twelve men were put together in one fossa.[8][9]

Semantic evolution

Cunha dates the sense “ditch” to the 14th century, and Houaiss the sense “cesspit” to the same century; the sense “grave” is now obsolete.[9][2] Vieira (1871) lists the pit dug in the earth, the grave, the trench dug by vine-growers round the stocks, the anatomical cavity, the vaulted pit for latrine waste and the soldiers' shelter.[10] In the 19th and 20th centuries geomorphology took up the word for a sunken stretch of the earth's crust, rendering English and German graben.[2] Brazilian slang has used estar na fossa “to be in the pit” for low spirits since about 1960.[2]
