The name of the month was recorded by the Venerable Bede thus:
|Antiqui Anglorum populi [...] annum totum in duo tempora, hiemis et aestatis dispertiebant, sex menses [...] aestati tribuendo, sex reliquos hiemi; unde et mensem, quo hiemalia tempora incipiebant, Ƿintirfylliþ appellabant, composito nomine ab hieme et plenilunio, quia videlicet a plenilunio ejusdem mensis hiems sortiretur initium [...] Ƿintirfylliþ potest dici compositio novo nomine hiemi plenium.||The old English people split the year into two seasons, summer and winter, placing six months — during which the days are longer than the nights — in summer, and the other six in winter. They called the month when the winter season began Ƿintirfylliþ, a word composed of "winter" and "full moon", because winter began on the first full moon of that month.|
