Pronunciation

  • Northern: [ˈfo̞k][1]
  • Balearic, Central, Northwestern, Valencia: [ˈfɔk][1]

Forms

foc m (plural focs)[1] Medieval texts write foch and ffoch, with ⟨-ch⟩ for the final /k/.[2][3]

Etymology

It is inherited from Latin focus (“hearth, fireplace”).[4][5][6][7][1] In Classical Latin the word meant the domestic hearth; in Vulgar Latin it came to mean fire in general, the element.[5] Coromines and Pascual date this use in Latin to at least the 4th century, when the word took the place of ignis (“fire”).[8]

The same Latin word is Occitan fòc, Spanish fuego, Portuguese fogo, French feu, Italian fuoco and Romanian foc.[1][9] The troubadours wrote Old Occitan foc and fuec.[1] A learned doublet, ⟨focus⟩, kept the classical sense of hearth before it came to mean the point where rays meet;[4][1] Coromines finds it, as ⟨foco⟩, in Labèrnia's dictionary of 1839.[4][1]

The origin of the Latin word is unclear.[10][1] De Vaan rejects a connection with fax (“torch”) as formally impossible.[10] Wiktionary lists proposals that derive it from Proto-Indo-European *bʰeh₂- (“to shine”) or, following Matasović, from *dʰegʷʰ- (“to burn”).[1]

Earliest recorded meaning

CICA's first record is in the Homilies de Tortosa, of the end of the 12th or the beginning of the 13th century.[11] Coromines finds the word from the beginnings of the language in its main senses, a bonfire, a fire set somewhere, and fire as an element: in Jaume I's chronicle the king's men light fires in more than three hundred places in the scrub at Capdepera, so that the Moors of Menorca will think a great army is camped there.[4] Llull uses it for the element, whose power ends where that of water begins.[4][2]

Semantic evolution

Llull treats fire as one of the four elements, hot and dry by nature.[2] Figurative senses appear in the 15th century: the ardour of the passions and creative inspiration in the poems of Pere Martines, and llançar foc for violent anger in a document of Igualada of 1447.[3] Medicine used dar foc for cauterizing, in a sermon of Vicent Ferrer and in Manuel Dieç's book on horses (1424), and Jaume Roig's Spill (1460) has metre foc for firing a bombard.[3]

The sense of the Latin word, a household, survives in foc 'inhabited house', which the DCVB records from 1358; it appears dozens of times in the census of 1359.[4] In Valencia a molí de foc is a steam-driven mill, as opposed to a molí de sang turned by animals, and foc de sant Antoni is the traditional name of a disease.[4] The firework display now called castell de focs is already castell de foc in the Baró de Maldà.[4] Words of the family are dated by Bruguera: afogar in Llull, fogar in 1803, desfogar about 1900 in Verdaguer.[6]

Fabra's dictionary of 1932 defines the word as the heat and light given off by a burning body, once held to be one of the four elements.[12]
