Etymology

It is from Latin āla (“wing”) + -ārius.[3][1] Etymonline explains ⟨āla⟩ from ⟨*axla⟩, originally the joint of the wing or arm, from Proto-Indo-European *aks- (“axis”).[4]

Köbler's earliest sources are Cicero and Caesar.[5] Köbler dates Cicero 81–43 BC and Caesar c. 50 BC.[5]

Semantic evolution

In military language it meant of the wing of an army, as opposed to the legions, of the auxiliary cavalry, as in Caesar and Livy; in the masculine plural, ālāriī were the auxiliary troops or cavalry.[3][2][6]
