Forms

fundar (first-person singular present fundo, first-person singular preterite fundei, past participle fundado)[1] Old Galician-Portuguese wrote both fundar and fũdar.[1] A private letter of 1567 still has the abbreviated spelling fũdou “he founded”.[2]

Etymology

It is inherited from Latin fundō (“to lay the foundations of”), written Old Galician-Portuguese fundar in the oldest texts.[3][4][1] Nascentes calls it a learned form.[5] García de Diego lists the old Galician form fondar with the sense “to go to the bottom”, and calls the Spanish form with ⟨u⟩ a learned word.[6]

The same Latin verb is Spanish fundar, Catalan fondar, Occitan fondar, French fonder and Italian fondare.[7][1] In Medieval Latin it was the usual word for founding a church or a monastery.[8][9]

The Latin verb is formed from fundus (“bottom, base”).[3][10][1] The noun goes back to Proto-Indo-European *bʰudʰmḗn (“bottom”), with cognates such as Sanskrit बुध्न (budhná, “bottom, root”) and the English word bottom.[1][10] fundir comes from a separate Latin verb meaning “to pour”.[1][11]

Earliest recorded meaning

Latin charters of 870 and 882 already use the verb for founding a church: baselica sita et fundata est in villa “a church situated and founded in the estate”.[12] The DDGM cites fundar from a document of 1234–1236, and Cunha dates the Portuguese verb to the 13th century.[12][4] Houaiss's first record is of the 14th century.[3]

Semantic evolution

The first sense was material: to lay the foundations of a building and raise it, which Cardoso glosses in 1569 with the Latin verb and Pereira in 1697 with the phrase “to lay foundations”.[13][14] From buildings it passed to institutions: Feijó wrote in 1734 that to found buildings or a religion is to give them a beginning, and that fundar-se em something is to make it one's basis.[15] Morais in 1789 adds “to establish on a principle, a fact, a testimony” and the old sense “to sound, to fathom”.[16]

Because of fundo “bottom” and “deep” the verb also means “to make deeper”, and Morais already records fundar huma vasilha, to fit a bottom to a cask, which Silva Bastos places in the Bairrada region and Houaiss labels European.[16][17][3] Brazilian dialects use it for water that grows deep, and for going deep into a place.[18]
