A more thorough explanation:

Definition: In articulo mortis is a Latin term that means "at the point of death." It is often used in legal contexts.

Example: A person who is terminally ill and has only a few hours to live may be considered to be in articulo mortis.

Explanation: The example illustrates the definition by showing how the term can be used to describe a person who is very close to death. In legal contexts, this term may be used to refer to situations where a person's last will and testament is being written or changed because they are in danger of dying soon.
