Let's break down the root "apo":
* "Apo" means "away from," "off," or "from."
When combined with "stello," which means "to send," the word "apostolos" implies someone sent away from a source with a specific purpose.
Therefore, an apostle is someone who is sent out by a higher authority, often with a divine mission or message. In Christian tradition, the apostles were chosen by Jesus to spread the Gospel.
Here are some other words derived from the Greek root "apo":
* Apology: A speech or action to defend oneself from criticism. ("apologia" means "defense" or "explanation")
* Apostrophe: A figure of speech where the speaker directly addresses a person, object, or idea that is not present. ("apostrophe" means "turning away")
* Apocalypse: A revelation or disclosure, often of something significant and unexpected. ("apocalypsis" means "uncovering" or "revealing")
