Pasch

"of or pertaining to Passover or Easter," early 15c., from Old French paschal (12c.) and directly from Late Latin paschalis, from pascha "Passover, Easter," from Greek pascha "Passover," from Aramaic (Semitic) pasha "pass over," corresponding to Hebrew pesah, from pasah "he passed over" (see Passover). Pasche was an early Middle English term for "Easter" (see Easter), and the older Dutch form of the word, Paas, was retained in New York.
