The story
- Proto-Indo-European*dʰegʷʰ-
- Latinfebruum
- LatinFebrua
- LatinFebruārius
- Middle EnglishFebruarie
- English todayFebruary
From Middle English Februarie, februari, februare, from Latin Februārius (“the month of the Februa”), from Februa (“the Purgings, the Purifications”), a Roman holiday two days after its ides (i.e., Feb. 15), + -arius (“-ary: forming adjectives”). Februa from februum (“purging”), from an earlier Sabine [Term?] word, possibly from Proto-Indo-European *dʰewh₂- (“smoke, haze”) and thus cognate with thio- (“sulfurous”) and Ancient Greek θεῖον (theîon, “sulfur”) or from Proto-Indo-European *dʰegʷʰris, an extension of the root *dʰegʷʰ- (“to burn”) and thus cognate with fever and febris. A relatinization abandoning Middle English feoverel, from Old French feverier, which itself displaced Old English solmōnaþ (“mud month”).
