sepulchre (n.) Look up sepulchre at Dictionary.com
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 (11c.), from Latin sepulcrum "grave, tomb," from root of sepelire "to bury," originally "to perform rituals on a corpse" (cf. Sanskrit saparyati "honors"). No reason for the -ch- spelling.
