In many languages "Easter" is a variation of Passover. "Pâques" in French for example, Pascha in Greek and Russian, Pascua in most Latin languages. In others (aome Slavic languages) it's a variation of "Great Day" ("Velikonoce" in Czech for example). " And so on. English and German are the only languages I know with a weird word for Easter.
Edit - also Passover is Pesach in Hebrew. So Pesach -> Pascha in Greek, then onwards to other languages. Or just "Great Day" (which finishes off Great and Holy week which is what the week leading up to Easter is in most languages).
