What is generally used to identify individual graves as a single object?

In the context of identifying individual graves, a marker is the most commonly used term. Markers serve as an important means of memorializing and recognizing the specific location of a grave. They can vary in size, shape, and material, but their primary purpose is to denote the presence of an individual burial site.

Markers often display the name of the deceased, along with other pertinent information such as dates of birth and death. By providing this information, markers help maintain a connection between the living and those who have passed away, creating a respectful and identifiable way to locate individual graves within a cemetery.

While other options might also relate to grave identification in some contexts, they do not specifically fulfill the role of marking individual graves in the same straightforward way that a marker does.
