What is the meaning of "post mortem"?

The term "post mortem" originates from Latin, meaning "after death." It is commonly used in various contexts, such as in the medical field to refer to examinations performed on deceased individuals to determine the cause of death. Additionally, the phrase can be metaphorically applied in other areas, like project evaluations, where it refers to analysis conducted after an event has concluded to assess outcomes or effectiveness.

Understanding this definition highlights the significance of the term, especially in legal, medical, and analytical discussions. The other options do not align with this definition and pertain to different contexts entirely. For example, "for this turn" refers to a different temporal context, "according to calculation; in proportion" focuses on mathematical or measurement interpretations, and "first appearance" indicates an initial occurrence, which does not relate to the concept of "post mortem."
