The word "apostle" generally refers to a person who is an early follower and messenger of a religious figure, particularly in Christianity, where it is specifically used to denote the twelve disciples chosen by Jesus. In a broader context, it can also mean a pioneering advocate or supporter of a particular cause or belief, working to spread its message and gain followers.
The word "apostle" originates from the Greek word "apostolos," meaning "one who is sent away" or "messenger." This term derives from the verb "apostellein," which means "to send forth." It further traces back to the prefix "apo-" meaning "from" and "stellein," meaning "to send."
