The word "protector" originates from the Latin protector, derived from protegere ("to cover in front," from pro- "forward" + tegere "to cover"). The suffix -or denotes an agent performing the action (e.g., "actor," "creator"). Historically, it was used for regents (e.g., "Lord Protector" in 17th-century England) and evolved into modern usage for guardians, defenders, or protective devices.
