What is the term for when a whole body is buried or placed in an above-ground mausoleum?

The term for when a whole body is buried or placed in an above-ground mausoleum is "internment." This term encompasses the act of placing the deceased in their final resting place, which can include burial in the ground or placement within a mausoleum.

Internment typically involves the physical act of burying the body, or interring it in a designated location, which reflects the cultural practices surrounding death and memorialization. While the other terms relate to different processes – such as exhumation (the act of removing a body from its burial place), cremation (the process of reducing the body to ashes through fire), and entombment (specifically referring to placing a body in a crypt or mausoleum) – internment is the broader term that refers to the final disposition of the body in both contexts of burial and above-ground placement.
