Confidence
Probable
Formation
Derivation
First attested
81–43 BC, Cicero
Ultimate origin
Proto-Italic (*wekslo-)

Pronunciation

  • Classical: [weːkˈsɪl.lũː][1]
  • Ecclesiastical: [veɡˈzil.lum][1]

Forms

vēxillum n (genitive vēxillī); second declension[1]

Etymology

It is the diminutive of vēlum (“sail, cloth”).[2][1][3] De Vaan derives ⟨vēlum⟩ from Proto-Italic *wekslo-, perhaps Proto-Indo-European *ueg-slo-, and notes that the diminutive shows a stem with a consonant before ⟨-slo-⟩; the root may be “to weave”, as in Welsh gwëu (“to weave”) and Old English wice (“wick”), or less likely “to convey”.[4] The OLD also compares the Welsh verb.[5]

Earliest recorded meaning

Köbler gives Cicero as its first author,[3] who asks “do you think desperate citizens will ever lack a standard to rally to?”.[5]

Semantic evolution

It is a military standard, a piece of cloth hanging from a crossbar on a pole, as in Cicero and Caesar;[5][2][1] Tacitus uses apud vexillum of veterans kept in service under the standard, and Cicero of the banner set up at the founding of a colony.[5] It is a banner given for distinguished service, as Suetonius' sea-blue banner that Augustus gave Agrippa after his naval victory, and a detachment of troops, as Livy's rank made up of three vexilla.[5][1]

In Christian Latin it is the standard of the Cross, vexillum crucis, the sign of the Cross;[6][7] Stelten describes the Vexillum as the Roman cavalry standard bearing a cross instead of an eagle.[6][7] In Medieval Latin it is also the banner that stands for the power of military command.[6]
