Forms

aquilō m (genitive aquilōnis); third declension[1]

Etymology

De Vaan, following Cohen, derives it most straightforwardly from Latin aquila (“eagle”) + -ō, the cold north wind being personified as a fast, aggressive bird of prey.[2][1] The OLD derives it instead from aquilus (“dark”), and Lewis & Short offer that adjective, for the stormy weather it brings, or aqua (“water”), for the wet.[3][4] De Vaan thinks the eagle itself may have been named from ⟨aquilus⟩.[2]

Earliest recorded meaning

De Vaan and Köbler date it from Naevius.[2][5] In the OLD's earliest quotation Ennius has the south wind and the north wind vying to raise the waves.[3]

Semantic evolution

It is the north wind, and more precisely in Vitruvius the north-north-east wind, between the north and the east.[3] Personified it is Boreas: Cicero mentions the story that the north wind carried off Orithyia at Athens.[3] As a point of the compass it is the north: Varro says that Europe lies to the north.[3] Church Latin glosses it north wind.[6] In New Latin it is also the kite.[1]
