Forms

borēus (feminine borēa, neuter borēum); first/second-declension adjective[1] Later poets such as Priscian scan it bŏrĕŭs, with short vowels.[2]

Etymology

It is borrowed from Ancient Greek βόρειος (bóreios, “northern”),[1][3][4] from Βορέας (Boréas, “the north wind”).[4] Within Latin it looks like boreās (“the north wind”) with the suffix -ēus.[4]

Earliest recorded meaning

Its first use is in a poetic fragment of Cicero, of the northern pole of the sky, the axis boreus.[2][5]

Semantic evolution

It stayed a learned, mostly poetic and technical word for “northern”.[1][2] Ovid has it of the northern pole in the Tristia, where some editors read the genitive of boreās instead.[2] A fragment of Suetonius says there are two poles on which the sky turns, the boreus, “which we call aquilōnius”, and its opposite.[6] Ammianus Marcellinus speaks of the northern side of Persia, Orosius of the northern Scythian, and Servius and Isidore of Seville use it of the pole.[6][2] Köbler finds it again in Aldhelm and in Waldo about 1060.[5]
