Origin

This character appears to represent armor by combining the idea of a protective covering with a structured form. The square component () suggests a boxlike or segmented structure, while the vertical line (丨) emphasizes the front-facing aspect. Together, these strokes create an image resembling the overlapping plates or sections of a suit of armor. Over time, the meaning expanded to include rankings and orderings, likely because armor grades were classified hierarchically—hence "A grade" or "first class." The character's versatility in Japanese comes from these extended meanings rather than changes to its visual form.
