c. 400 Servius More words from the 4th century

Forms

februus (feminine februa, neuter februum); first/second-declension adjective[1][2]

Etymology

The origin is uncertain.[3] De Vaan takes februum “a means of purification” to be this adjective used as a noun, and the adjective in turn to presuppose an older ⟨*febro-⟩ “purification”.[3] He reconstructs it as Proto-Italic *f(w)esro- or *feχʷro-: the first would fit Walde and Hofmann's Proto-Indo-European *dʰues-ro- (“the smoking”), with a shift of meaning from smoking to purifying, but he cannot exclude the root of febris “fever”, from *dʰegʷʰ-ro- (“the burning”).[3] Varro calls ⟨februm⟩ a Sabine word for a means of purification.[4]

Earliest recorded meaning

As an adjective it is rare: Martianus Capella calls Juno Februa, the purifier.[1][2] The earliest dated source for the word is Servius, who names Februus as an underworld god in his commentary on the Georgics.[5]

Semantic evolution

Used as a name, Februus was an Etruscan god of the underworld to whom sacrifice was made in mid-February, as Macrobius reports;[2][5] and Isidore of Seville, explaining the month's name, identifies him with Pluto and rejects a derivation from febris.[6] The noun februum and the month name Februārius belong to the same family.[3]

In late and medieval verse februus served as another name for the month of February, and as an adjective “of February”.[1][7] Wandalbert and Walahfrid Strabo use it so in their calendar poems,[7] and British writers have it both for the month and, following Isidore, for Pluto.[8] In Neo-Latin, Celtis still writes Februae … Calendae for the first of February.[9]
