acciaio

Forms

acciaio m (plural acciai)^[1] Old Italian forms include acciaro, Old Italian açaro, Old Italian acé and Old Italian azzaio.^[2] The poetic acciar was used by Petrarch and Ariosto.^[3][4]

Etymology

It is inherited from Late Latin aciārium (“steel”), from aciēs (“point, cutting edge”).^[4][5][6][1] Nocentini explains the Late Latin word as an adjective used as a noun, short for a phrase with ferrum (“iron”) meaning “iron for cutting edges”, and the Treccani as the hardened iron from which the points of weapons were made.^[5][7] The LEI notes that the word, recorded in glosses, replaced Latin chalybs (“steel”), taken from Ancient Greek χάλυψ (khálups).^[3]

It lives on in all the Romance languages except Romanian and Romansh: French acier, Occitan acer, Catalan acer, Spanish acero and Portuguese aceiro.^[3][5][8] In northern Italy, except eastern Emilia and Romagna, it was replaced by Vulgar Latin *aciāle, the source of Old Italian acciale.^[3][8] The ending shows the Tuscan change of ⟨-ariu⟩ to ⟨-aio⟩, while acciaro is a dialect outcome.^[9][4]

The Latin noun is related to ācer (“sharp”) and acuō (“to sharpen”), and goes back to Proto-Indo-European *h₂eḱ- (“sharp, pointed”).^[10][1] ago belongs to the same family.^[5][11]

Earliest recorded meaning

Medieval Latin at Bologna has azarum in 1252 and azarium in 1255.^[4] The TLIO's first Italian record is in the Lucchese poet Bonagiunta Orbicciani, in the middle of the 13th century, for a very hard iron alloy used especially for weapons.^[2] GRADIT dates the word to the late 12th century, the Zingarelli to 1268, and DELI to the Novellino at the end of the 13th century.^[6][12][4]

Semantic evolution

Old Italian already used steel as a figure of hardness and strength, for weapons by metonymy, and for the fire steel later called acciarino.^[2] Giovanni Villani describes the iron crown given at Milan as di fino acciaio forbito a spada (“of fine steel polished like a sword”).^[13][7] In 1532 Ariosto wrote acciar where the earlier edition of the Orlando furioso had metal, and poets used acciaro for a sword from 1561.^[4]

The modern sense, an alloy of iron and carbon made from molten pig iron, replaced the older general name for hard iron.^[7][4] acciaieria “steelworks” is recorded in 1886, perhaps modelled on French aciérie.^[4][11] The patto d'acciaio (“Pact of Steel”) was the alliance between Mussolini's Italy and Hitler's Germany signed on 22 May 1939.^[14]
