Origin

This character combines the idea of "two" through its components. The horizontal line at the top represents one, while the box shape below it (formed by the enclosing strokes) suggests another unit or section. The mountain-like strokes inside reinforce the sense of something doubled or balanced on both sides. Together, these elements visually suggest a symmetrical arrangement of two parts, which led to the meaning "both" or "two." Over time, this character came to be used for counting things that naturally come in pairs, like the two wheels of a carriage, and eventually for an old Japanese coin that was valued at two of a smaller denomination.
