fogo m (plural fogos, metaphonic)[1] The singular has closed /o/ and the plural fogos open /ɔ/.[2][1]
Etymology
It is inherited from Latin focus (“hearth, fireplace”), written Old Galician-Portuguese fogo in the oldest texts.[2][3][4][1] It is the popular outcome of the Latin word, and foco is its learned doublet.[2][1] In Latin the word meant the hearth; it was used in the sense of ignis (“fire”) from the imperial period, at least from the 4th century.[5][6]
The same Latin word is Galician fogo, Spanish fuego, Catalan foc, Occitan fuòc, French feu, Italian fuoco and Romanian foc.[1][7]
The origin of the Latin word is uncertain, and de Vaan finds no convincing etymology: a link with fax (“torch”) is impossible in form, and Hamp's explanation of the Latin word as a back-formation from foculus (“small stove”) runs into chronological problems.[8] Wiktionary records comparisons with բոց (bocʻ, “flame”), with *bʰeh₂- (“to shine”) and with *dʰegʷʰ- (“to burn”).[1]
Earliest recorded meaning
Latin charters of 994 and 998 already have the Romance spelling: et inde in fogo lopare and pro fogo que cedarunt et fecerunt damno “for the fire that they set and did harm with”.[9][2] In the 13th-century Cantigas de Santa Maria the word means fire, including the fire of hell (fog'infernal) and the flames of Mount Etna, and it names a disease, fogo de San Marçal or mal do fogo.[9]
Semantic evolution
Medieval texts use fogo de San Marçal and fogo salvage for a skin disease with blisters.[9][10] From the sense “hearth” came “dwelling, household”: in 1340 the fogo or paga dos fogos was a tax paid by every householder of Chaves.[11][2] The Spanish word has the same sense, which DCECH calls common to the western Romance languages.[6]
Cardoso (1569) and Barbosa (1611) render the word by Latin ignis.[12][13] Bluteau derives it from Greek phôs “light” or, as others held, from focus.[14] Figurative senses (brilliance, ardour, passion, creative inspiration), the gunfire of firearms and the command fogo! all go with the word today, and Brazilian Portuguese adds “drunkenness” and “sugar-cane spirit”.[2] The island of Fogo in Cape Verde is named after the fire of its volcano.[15]
