sepulchre: [12] Sepulchre comes ultimately from Latin sepelīre ‘bury, inter’. From its past participle sepultus was derived the noun sepulcrum ‘burying place, tomb’, which passed into English via Old French sepulcre. There is no etymological justification for the ch spelling.

also sepulcher, c. 1200, "tomb, burial place," especially the cave where Jesus was buried outside Jerusalem (Holy Sepulcher or Saint Sepulcher), from Old French sepulcre "tomb; the Holy Sepulchre" (11c.), from Latin sepulcrum "grave, tomb, place where a corpse is buried," from root of sepelire "to bury, embalm," originally "to perform rituals on a corpse," from PIE *sep-el-yo-, suffixed form of root *sep- (2) "to handle (skillfully), to hold (reverently);" cognates: Sanskrit saparyati "honors." No reason for the -ch- spelling, which dates to 13c. Whited sepulchre "hypocrite" is from Matt. xxiii.27.
