ferro

Forms

ferro m (plural ferri, diminutive ferrétto or ferrettìno, (less common) ferrìno or ferrolìno or ferrùzzo/(rare) ferrùccio, pejorative ferràccio)^[1] Old forms include Old Italian fero, Old Italian fer and Old Italian fierro.^[2]

Etymology

It is inherited from Latin ferrum (“iron; iron tool”).^[3][4][5][1] The word is pan-Romance: French fer, Occitan ferre, Catalan ferre, Spanish hierro, Portuguese ferro, Sardinian ferru and Romanian fier.^[4][6] Some Latin derivatives came into Italian as learned words (ferramento, ferreo, ferruginoso), while ferraio continues Latin ferrarius by popular descent.^[3]

The origin of the Latin word is unknown.^[3][7] Iron came late to the speakers of Indo-European, so the metal has no common Indo-European name.^[8][4] The double ⟨rr⟩ probably comes from an older ⟨rs⟩, an older Latin *fersom.^[4][1] De Vaan calls it a loanword from an unidentified source, possibly a Phoenician dialect, comparing Phoenician 𐤁𐤓𐤆𐤋 (brzl) and Classical Syriac ܦܪܙܠܐ (parzlā).^[7][1] Nocentini likewise compares Biblical Hebrew בַּרְזֶל (barzel) and Akkadian parzillu but leaves the direct source open.^[4] Battisti and Alessio thought of an Etruscan counterpart of the Semitic word, tied to the old iron-working of Etruria;^[9][1] Wiktionary also allows a passage through Etruscan.^[9][1]

Earliest recorded meaning

The TLIO's first record is in the Libro of Uguccione da Lodi, from Cremona, early in the 13th century, in the sense of the grey metal and objects made of it.^[2][4] DELI's earliest dated sense is “sword, blade”, before 1257 in Bonagiunta Orbicciani, and the metal itself is recorded before 1290 in Guido delle Colonne.^[3][5]

Semantic evolution

From the metal the word passed to things made of it: a sword or other weapon (venire ai ferri, to come to blows), and in the plural the chains of prisoners (before 1306, Iacopone).^[2][3] Later senses name particular tools: the knitting needle (ferro da calza, 1585), the curling iron (before 1556), the flat iron (ferro da stiro, which DELI thinks a Roman phrase) and the grill (ai ferri), which purists still disliked in 1905.^[3] In 20th-century slang ferro is also a pistol.^[10]

Figurative uses rest on the hardness of iron: di ferro is “very strong” or “inflexible” (salute di ferro, disciplina di ferro), and toccare ferro (“touch iron”) is the gesture against bad luck, from the belief that gripping a piece of iron or a horseshoe protects from the evil eye.^[3][5] The proverb battere il ferro finché è caldo and the età del ferro of prehistory are fixed expressions of the modern language.^[5][11] In chemistry it is the element Fe, and in medicine the iron in the blood.^[5]
