Pronunciation

  • Classical: [ˈfɛr.re.ʊs][1]
  • Ecclesiastical: [ˈfɛr.re.us][1]

Forms

ferreus (feminine ferrea, neuter ferreum); first/second-declension adjective[1]

Etymology

It is formed from Latin ferrum (“iron”) + -eus.[2][1][3] De Vaan takes ⟨ferrum⟩ as a loanword from an unidentified source, possibly a Phoenician dialect, comparing the Phoenician and Syriac words for “iron”.[4]

Earliest recorded meaning

Köbler gives Ennius as its first author, whose Annals have fit ferreus imber, “a shower of iron falls”, of weapons;[5][2] Plautus has iron nails.[5][2]

Semantic evolution

It is made of iron, and in poetry of weapons;[2] manus ferrea and lupus ferreus are grappling irons.[2] It is of the colour or hardness of iron, and saecula ferrea or aetās ferrea is the Iron Age, as in Tibullus.[2] Of buildings it is iron-barred, and of cavalry ironclad (Sallust).[2] By transfer it is hard-hearted (Cicero: I am not so iron as not to be moved by a brother's grief), cruel, untiring, as Virgil's voice of iron, inflexible, of fate, and shameless, as Cicero's “iron face” of Piso.[2]

Church Latin glosses it “made of iron, iron”.[6]
