Another name for a dead body is corpse. You might hear it on TV crime shows, but a corpse doesn't have to be a crime victim, just any lifeless body.
The words corpse and "corps" are often confused, and with good reason — both came from the Latin word corpus, meaning "body," and up until the 19th Century, both referred to a dead person. Around that time, the word with the "e" at the end was established as the word for a person's remains, while the other spelling was relegated to a "body" of people working together or in a military division, and very much alive!
