What do we call a commemorative inscription found on a tomb or cemetery marker?

The term for a commemorative inscription found on a tomb or cemetery marker is "epitaph." An epitaph is specifically designed to honor and remember the deceased, often containing a meaningful message, quote, or reflection on the person's life. This inscription serves not only as a tribute but also as a lasting reminder for future visitors about the individual who has passed away.

In contrast, other options like "memorial," "inscription," and "obituary" have different meanings or applications. A memorial generally refers to a structure, ceremony, or event that commemorates a person or group, rather than the specific text inscribed on a gravestone. An inscription is a broader term that can apply to any engraved text, not necessarily linked to a tomb, and doesn’t imply commemorative intent like an epitaph. An obituary is a published notice of a person's death that may summarize their life but is not inscribed on a marker. Thus, "epitaph" precisely captures the essence of a commemorative inscription found on a tomb or cemetery marker.
