Common characteristics; shared nature; commonality. The qualities or attributes that are shared across multiple things, individuals, or groups.

Often contrasted with 个性 (individuality; unique characteristics). Used in philosophical, academic, and analytical contexts to discuss what unites members of a category. The pair 共性与个性 (commonality and individuality) is a classic dialectical pair in Marxist philosophy as taught in Chinese schools.
