forno

Forms

forno m (plural forni)^[1] The old plural was also feminine, le fornora.^[2][3][4] Old Italian forms include furno and Old Italian furnu.^[5]

Etymology

It is inherited from Latin furnus (“oven; bakehouse”), beside an older fornus used by Plautus and Varro.^{[6][7][8][9][1]} The word is Pan-Romance: French four, Occitan forn, Catalan forn, Spanish horno, Portuguese forno, Sardinian furru and Aromanian furnu.^[7][10] The variant with ⟨o⟩ survives in Sardinian, Lucanian and northern Calabrian.^[11]

Wiktionary traces the Latin word to Proto-Italic *fornos and Proto-Indo-European *gʷʰr̥nós, from Proto-Indo-European *gʷʰer- (“to be warm”).^[1] Nocentini and the OLD compare Old Irish gorn (“fire”) and a Sanskrit word for “heat”, and relate it to formus (“warm”).^[7][9][1] Battisti and Alessio doubt the connection, because of the alternation of the vowel and the forms of fornāx (“furnace”) and fornix (“arch”).^[11] Devoto explained the noun as a cross of the words for “warm” and “arch”.^[12]

Earliest recorded meaning

The TLIO's first record is in the Venetian Proverbia que dicuntur, of the last quarter of the 12th century.^[5] DELI's first record, the vaulted masonry oven for baking bread, is the Breve di Montieri of 1219, which rules on bread from the oven: Del pane del forno.^[6][4]

Semantic evolution

By 1273 the word also named the bakery.^[6] Old Italian used it for the bread baked at one time, for a furnace for refining metal, especially silver, and figuratively for a place of torment.^[5] Vannoccio Biringuccio, before 1537, has the industrial sense, an apparatus kept at a high temperature to transform materials; in electrical engineering the term follows French four and German Ofen.^[6][11]

Tuscan proverbs give caldo come un forno “hot as an oven” and chi non è in forno, è sulla pala, said of someone at risk of another's misfortune.^[3] The sense “very hot place” is dated to 1853 and “wide-open mouth” to 1875.^[6] In the theatre far forno “to play to an empty house” is a calque of French faire four (1659), perhaps because the empty hall, with its lights put out, was as dark as an oven.^[6][11] Political journalism speaks of the politica dei due forni, seeking support now from one side, now from the other.^[13]
