Two horizontal strokes, representing the number two.
About
The character "二" originates as a simple ideogram representing the number two through two horizontal strokes, a structural form that has consistently served as its numeral designation. Etymologically, it functions as a direct visual symbol for the quantity, with the strokes typically written as parallel lines, though in some script styles the upper stroke is rendered shorter. While its primary meaning as the cardinal number two has remained central, the character has developed extended uses over time, such as denoting an ordinal position in terms like "第二" for second, or indicating duality and secondary qualities in compounds including "二重" for double and "二手" for second-hand, reflecting a semantic broadening from its original numerical function.
