The word "vanguard" originates from Old French avant-garde, combining avant ("before" or "front") and garde ("guard"). It originally referred to the front division of an army, tasked with scouting and protecting the main force. Over time, it evolved metaphorically to describe pioneers or leaders in any field, such as art, technology, or social movements. The morpheme van preserves the idea of "front," while guard retains its protective connotation, together forming a vivid image of leadership and protection.
