Here are some other ways to think about the meaning:
* To remove from a grave or tomb: This is the most common usage.
* To bring to light something that was hidden or forgotten: This is a figurative usage, where the thing being "exhumed" isn't literally buried.
Here are some examples of how "exhumed" is used in a sentence:
* The police exhumed the body to investigate the cause of death.
* The author exhumed old diaries to write a biography.
* The historian exhumed forgotten documents to support his theory.
