What is the act of placing a deceased body in a grave or tomb called?

Interment refers specifically to the act of placing a deceased body into a grave or tomb. This term encompasses all forms of burial-like practices where the body is secured within the ground or a grave site. It is a common practice in many cultures and involves preparing the body, often in a casket, and subsequently laying it to rest in a designated location.

While terms such as burial and entombment also relate to the disposition of a body, interment is the more generalized and widely accepted term. Burial often refers specifically to the act of placing the body underground, while entombment refers to placing the body in a structure like a mausoleum or crypt. Cremation, on the other hand, is a completely different process where the body is reduced to ash through burning and does not involve a grave or tomb at all. Therefore, interment is the most accurate choice in the context of placing a body in a grave or tomb.
