Forms
fundo (feminine funda, masculine plural fundos, feminine plural fundas)[1] Houaiss records fomdo (1077), fondo in the 13th century and fundo from the 14th.[2]
Etymology
It is inherited from Latin fundus (“bottom; a piece of land”), written Old Galician-Portuguese fondo and fundo in the oldest texts.[2][3][4][1] Houaiss, Cunha and the REW take both the noun and the adjective from it; the REW notes that the Italian, Spanish and Portuguese words are also adjectives meaning “deep”.[2][3][5] Cornu, quoted by Nascentes, explains the adjective instead as Latin profundus (“deep”) with the first syllable dropped, because pro- was felt as an intensive, and the DDGM's glossary of a text of 1253–1254 derives the word from the same Latin adjective.[6][7] Corominas gives that explanation for Spanish hondo, through Old Spanish perfondo.[8]
The same Latin noun is Galician fundo, French fond, Italian fondo and Romanian fund.[5][1]
De Vaan reconstructs Proto-Italic *fundo- and Proto-Indo-European *bʰudʰmḗn (“bottom”), from an older genitive form; the same word is Sanskrit बुध्न (budhná, “bottom”), Ancient Greek πυθμήν (puthmḗn, “bottom”) and Old English botm, the source of bottom.[9][1]
Earliest recorded meaning
Houaiss's first date, 1077 for the spelling fomdo, is taken from Machado; the record itself is not quoted.[2] A Galician-Portuguese document of 1253–1254 already has et o preyto todo como andou de fundo “and the whole suit as it went from the bottom”, that is, from the beginning.[7]
Semantic evolution
The noun meant the lowest part of a vessel, of a river and of the sea, and early came to mean the essence or foundation of something;[3] Cunha dates the senses “depth”, “innermost part”, “capital” and “ballast” to the 13th century.[3] Barbosa in 1611 gives fundo with Latin fundum and the adjective funda cousa “a deep thing”;[10][11] Morais in 1789 has deitar a fundo “to sink”, also “to pull down”.[10][11]
Modern Portuguese uses the noun in finance (a fund, capital set aside), in painting and the theatre (the background), in sport (long-distance races) and for the collection of a library or museum.[2][1] In Brazilian informal speech the adjective means “ill-prepared, weak at something”: um aluno fundo em química.[2][12]
