About
The character 二 (èr) is a simple ideogram formed by two parallel horizontal strokes, visually representing the number two. This direct graphic representation has been the core method for indicating the quantity two since the writing system's inception. Besides its primary role as a cardinal number, its meaning extended to ordinal concepts like "second" in a sequence. It can also function as an adjective in compounds to describe something as duplicate, secondary, or characterized by duality.
