Etymology

The word "guardian" originates from Old French "gardien," derived from "garder" (to guard or protect), which itself traces back to Frankish *"wardōn" (to watch or defend). The suffix "-ian" (from Latin "-ianus") denotes a person connected to a role or function. Over time, "guardian" evolved to signify not just physical protection but also legal and moral stewardship, reflecting its dual roots in military vigilance (guard) and personal responsibility (ian).
