Formation
Derivation
First attested
81–43 BC, Cicero
Ultimate origin
Proto-Indo-European (*h₂er-)

Pronunciation

  • Classical: [ar.maːˈtuː.ra][1]
  • Ecclesiastical: [ar.maˈtuː.ra][1]

Forms

armātūra f (genitive armātūrae); first declension[1]

Etymology

It is formed from armō (“to arm”) with the suffix -ūra.[2][3][1] The verb comes from arma (“weapons”), which de Vaan traces to Proto-Italic *armo- and Proto-Indo-European *h₂(e)r-mo- (“fitting”), from the root *h₂er- (“to join, fit”); the meaning developed from “what is fitted together” or “tools” to “weapons”.[4][1]

Earliest recorded meaning

Köbler gives Cicero as its first author,[5] whose letters say that Deiotarus had thirty cohorts “armed in our manner”.[2][6]

Semantic evolution

It is a type of military equipment or arms, as Cicero's varied equipment of infantry and cavalry, and levis armātūra is light-armed troops, as in Cicero and Caesar.[2][6] Suetonius uses it of a troop of gladiators, the Thracians whom Titus favoured, and inscriptions of the later army name a rank or class of soldier of uncertain meaning.[2]

The TLL notes that it is never a noun of action, and that it lives on in Italian armatura, French armure and Spanish armadura.[3] In medieval Latin it is a ship's rigging, equipment including weapons and armour, armour itself, a single weapon and a coat of arms.[7] English armature comes from it, first for an armed force and since the mid-15th century for armour.[8]

  • c. 75–c. 150 AD – Suetonius of a troop of gladiators.[2][5]
