O.E. Eastre (Northumbrian Eostre), from P.Gmc. *Austron, a goddess of fertility and sunrise whose feast was celebrated at the spring equinox, from *austra-, from PIE *aus- "to shine" (especially of the dawn). Bede says Anglo-Saxon Christians adopted her name and many of the celebratory practices for their Mass of Christ's resurrection. Ultimately related to east. Almost all neighboring languages use a variant of Latin Pasche to name this holiday.
