　With Halloween just around the corner, today we will explore the world of ghosts in this program! The Merriam-Webster online dictionary says the word "ghost" goes back a thousand years to the "earliest recorded evidence of the language." The first meaning of "ghost" was "the seat of life or intelligence." And it still has that meaning in some expressions.

　However, today, the word "ghost" usually means the soul of a dead person. This meaning is based on the idea that a person's spirit and body are separate. The spirit can continue existing long after the body has died.

　"Ghost" can also be a verb. In the 1880s the term ghost meant a person who works in secret for another person. Ghostwriters produce speeches for politicians. They also produce books for authors who want to tell their life stories but are not professional writers.

You can ghost from a party. You can even ghost from a relationship. This is when you stop communicating with someone because you are
