Forms

afundar (first-person singular present afundo, first-person singular preterite afundei, past participle afundado)[1] Old Galician-Portuguese wrote afondar and affondar in the 13th century;[2][3] afundar and affundar appear in the 14th.[2][3]

Etymology

Houaiss, Aurélio, the DLP and Priberam analyse it as formed from Portuguese a- + fundo + -ar, from fundo “bottom”.[2][4][5][6] Machado, Wiktionary and Porto Editora instead derive it from Vulgar Latin *affundō (“to sink”), made of ad- and fundus (“bottom”), written Old Galician-Portuguese afondar in the oldest texts.[7][1][8] Meyer-Lübke lists the Romance verbs under the Latin form but notes that the Romanian one, and perhaps the others, may be new formations in each language.[9]

The verb is Galician afondar, Spanish ahondar, Catalan afondar, Italian affondare and Romanian afunda in the other Romance languages.[9][1][10]

Earliest recorded meaning

The Cantigas de Santa Maria (cantiga 112) tell how as naves dos pagãos eno mar se afondarom “the ships of the pagans sank in the sea”.[7] A 14th-century text has como se o mundo todo se houvesse a afundar “as if the whole world were to sink”.[7]

Semantic evolution

Cardoso (1569) and Barbosa (1611) translate it with Latin demergo “to plunge, sink”.[11][12] Bluteau (1712–1728) gives meter a pique “to send to the bottom” and the reflexive afundar-se “to go down”.[13] Morais (1789) adds the senses “to deepen by digging” (a well, a mine, a foundation) and “to put a new bottom on a vessel”.[14]

Figurative senses followed: to make something vanish, to examine a matter in depth, and to fall into ruin.[15][16] Brazilian school slang uses it for making a pupil fail an exam with hard questions, and in basketball it means to dunk.[4][6][1]
