What term refers to the slave who accompanied a boy to school in ancient Rome?

The term that refers to the slave who accompanied a boy to school in ancient Rome is "Paedagogus." In the Roman educational system, a Paedagogus was specifically responsible for the care and instruction of young boys, often serving as a guide to help them navigate their daily activities, including their schooling. This role was distinct from that of a tutor, who would provide academic instruction in subjects. The Paedagogus was often a trusted slave who ensured the child's safety and proper behavior while traveling to and from school and during lessons.

Understanding the context of the other terms clarifies why "Paedagogus" is the correct choice. A pedagogue in a modern context may refer to a teacher or educator but does not specifically encompass the role of a slave in ancient Rome. A mentor, while a broader term for a guide or teacher, does not align specifically with the historical role of a slave accompanying a pupil. A tutor generally refers to a private teacher and does not imply the specific responsibility of accompanying students as a Paedagogus would have. Thus, "Paedagogus" is the most accurate term for this role in ancient Roman society.
