Pronunciation

  • Classical: [aːˈɫaː.rɪs][1]
  • Ecclesiastical: [aˈlaː.ris][1]

Forms

ālāris (neuter ālāre); third-declension two-termination adjective[1]

Etymology

It is from Latin āla (“wing”) + -āris,[2][1] from ⟨āla⟩ in its military sense of a wing of the army.[3][4] De Vaan traces ⟨āla⟩ to Proto-Italic *akselā- (“armpit, wing”) and Proto-Indo-European *h₂eḱs-(i-) (“axle, armpit”).[5]

Earliest recorded meaning

Livy has it first, of auxiliary cohorts (alares cohortes) with their commander.[2][3]

Semantic evolution

It stayed a military term.[3] An inscription from Africa, from a speech of the emperor Hadrian, speaks of the exercises of the alares, and other inscriptions of their decurions.[2][3] As a noun in the plural, alares were the auxiliary troops, especially cavalry: Tacitus has Pannonian alares and sets them beside the legionaries, and the Theodosian Code beside the cohortales.[2][3][4] Vegetius speaks of equites alares.[3] Glossaries render it by caballarius and by a Greek phrase for commanders of horsemen.[6]

Timeline

  • 59 BC–17 AD – Livy speaks of alares cohortes.[2][7]
  • 98–115 AD – Tacitus uses alares for auxiliary troops.[2][7]
  • c. 400 AD – Vegetius speaks of equites alares.[3][7]

Usage notes
