Which word refers to something occurring after death?

The term that accurately refers to something occurring after death is "posthumous." This word is derived from Latin, where "post" means after, and "humus" means earth or ground, specifically in the context of burial. As such, posthumous is commonly used to describe events or recognitions that take place after an individual's death, such as posthumous awards, publications of works, or acknowledgments. This concept is important in various fields, including literature and law, where recognition or actions are given consideration after the subject has passed away.

The other options do not convey the same meaning. "Antemortem" refers to events or conditions that occur before death. "Premature" typically describes something occurring too early and does not specifically relate to the time of death. "Afterlife" refers to the existence or state of a person's consciousness or soul after death, which is a different concept altogether and does not focus on events occurring after death in a temporal context.
