Forms

fundir (first-person singular present fundo, first-person singular preterite fundi, past participle fundido)[1] Old Galician-Portuguese had fonder beside fundir, fudir and fondir in the 14th century.[2][3][4]

Etymology

It is inherited from Latin fundō (“to pour, melt”).[2][3][1] The oldest texts have Old Galician-Portuguese fonder beside Old Galician-Portuguese fundir.[2][3][1][5] Nascentes calls it semi-learned.[6]

The same Latin verb is Italian fondere, French fondre, Occitan fondre, Catalan fondre and Sardinian fundere.[7] Spanish has it twice: the learned Spanish fundir “to melt”, recorded from about 1250, and the popular hundir “to sink”, which first meant “to destroy, ruin”.[8][9]

The Latin verb goes back to *hundō, a nasal present of Proto-Indo-European *ǵʰewd- (“to pour”), an extension of *ǵʰew-; its cognates include Ancient Greek χέω (khéō, “I pour”) and Gothic 𐌲𐌹𐌿𐍄𐌰𐌽 (giutan, “to pour”).[1]

Earliest recorded meaning

The Crónica Troiana tells of statues being melted with gold and cast in a hollow mould (fonderõ nas con ouro… deytaron delas en hũ molde uão), and the Galician General Estoria says that the heat melted metals from their veins (a caentura… fondeu metaes de venas).[4] Houaiss and Cunha date the verb to the 14th century.[2][3]

Semantic evolution

Besides melting and casting metal, the 16th- and 17th-century dictionaries record fundir “to yield, produce”, which Cardoso (1569) and Barbosa (1611) translate with Latin reddo;[10][11][2] Houaiss still lists the sense “to give a return”.[10][11][2] Vieira's dictionary (1871–1874) adds the figurative “to squander” and a commercial use.[12] The sense “to merge, join into one” is recorded in Houaiss, Aurélio and the DLP, as in companies or estates that are merged.[2][13][5] Brazilian informal speech uses it for losing one's head, fundir a cuca, and it is said of an engine that seizes or a light bulb that burns out.[2][1]

Timeline

  • 14th century – fonderõ in the Crónica Troiana;[4][2][3] Houaiss's and Cunha's first records.[4][2][3]

  • 1569 – Cardoso glosses fundir “to yield”.[10]
