Etymology
It is inherited from Latin ferrum (“iron”), written Old Galician-Portuguese ferro in the oldest texts.[2][3][4][1]
The same Latin word is Galician ferro, Spanish hierro, Catalan ferro, French fer, Italian ferro and Romanian fier.[5][6][1] Spanish had the older form fierro, recorded in a document of Cardeña in 1065;[7][8] Corominas notes that this form was preferred in parts of Spain into the 19th century and still prevails in much of Spanish America.[7][8]
The Latin word has no Indo-European etymology.[9][10] De Vaan thinks it a loanword from an unidentified source, possibly a Phoenician dialect, comparing the Phoenician and Syriac words for iron.[9][1] The DHLF recalls that the working of iron reached the Indo-European area late, after bronze, and that the names of the metal differ from one language to another.[10]
Earliest recorded meaning
Houaiss gives 1136 as the first date, from Machado's records.[2] Cunha places the first record in the 13th century, and the Cantigas de Santa Maria already speak of un bordon de ferro “an iron staff” and of prisoners thrown en carcer… e en ferros “into prison and into irons”.[3][11] The Crónica Geral uses ferro for the iron head of a lance and has the phrase a ferro et a fogo “with iron and with fire”.[11]
Semantic evolution
Already in the medieval texts the word named the metal, a thing made of it such as a spearhead, and, in the plural ferros, the shackles of a prisoner.[11][12] Morais (1813) records the curling-iron, the head of a lance or arrow and the sense “anchor” in lançar ferro “to cast anchor”;[13][4] Nascentes takes that nautical sense from Catalan.[13][4] Figueiredo (1899) adds the brand burned on a horse, slang “money”, and the plural for fetters and prison.[14]
Modern Portuguese uses ferro for appliances of the metal, above all the ferro de passar or ferro de engomar for pressing clothes.[2][1] Brazilian slang gave it the senses “sugar-cane spirit”, “handgun” and “a hard situation”.[2][15][1] The word lives on in the Portuguese creoles (Kabuverdianu féru, Sãotomense felu) and passed into Tetum as ferru.[1]
