The word "guide" originates from the Old French "guider," meaning "to lead or direct," which itself derives from the Frankish *wītan ("to show the way"). The root "gui" preserves the idea of direction or path, while the "-de" suffix is a remnant of the Old French verb ending. Over time, the term evolved to encompass both the person who leads and the act of leading, reflecting its dual role in English.
