Question: What is the meaning of the Hebrew letters "peh nun" (PN) on a tombstone?
These Hebrew letters are an abbreviation, and are often marked as such by the inclusion of diagonal marks between the letters, thus: P"N. They stand for the words "poh nikbar" (masculine) or "poh nikberah" (feminine), meaning "here lies buried".
A poetic and less common variant is P"T, "poh tamun" or "poh temunah", meaning, "here lies hidden".
It is traditionally correct to include one of these designations when a marker is placed on an occupied grave. When putting up a marker, without a body being buried in that grave, the letters are omitted. That is done when there is no body to bury, such as when someone has been lost at sea, or in an all-consuming fire, and there are no available bodily remains to lay to rest.
Other Hebrew information that it is correct to include on a gravestone include the name of the deceased, including the parents' names, for example: "Ploni ben Almoni", "x, son of y"-- "bat" for "daughter", instead of "ben", when a woman is buried. It is also proper to include the Hebrew date of death, known as the "yahrzeit" date. Finally, on the bottom of the gravestone, it is customary to write five letters, an abbreviation of a five-word prayer: T' N' TS' B' H', standing for "tehi nishmato (nishmatah, for a woman) tserurah bitsror ha-chayyim, "let his/her soul be bound up in the bundle of life eternal."
