epitaph (n.)

"inscription on a tomb or monument," mid-14c., from Old French epitaphe (12c.) and directly from Medieval Latin epitaphium "funeral oration, eulogy," from Greek epitaphion "a funeral oration," noun use of neuter of epitaphios (logos) "(words) spoken on the occasion of a funeral," from epi "at, over" (see epi-) +  taphos "tomb, burial, funeral," related to taphē  "interment," thaptō "to bury," which is of uncertain origin. It is traditionally derived (along with Armenian damban "tomb") from a PIE root *dhembh- "to dig, bury," but there are doubts, and Beekes writes, "Armenian and Greek could well be borrowings; IE origin is uncertain." Related: Epitaphial. Among the Old English equivalents was byrgelsleoð.
