-agog: "leader, guide, or conductor."
It is derived from the Greek word "ἄγω" (ago), meaning "to lead, to conduct, or to drive."
While not commonly used in modern English, examples of words with the "-agog" suffix include:
* Pedagogy: The art or science of teaching. (From Greek "paid-" meaning child and "agog")
* Demagogue: A political leader who appeals to the emotions and prejudices of people. (From Greek "demos" meaning people and "agog")
It's important to note that "-agog" is not interchangeable with the suffix "-logy," which signifies "study of." For example, "biology" means "study of life," whereas "bio-agog" (if it existed) would mean something like "leader of life" or "life conductor."
