The word 识别 is formed through the combination of two conceptual building blocks: the character 识, which carries the core idea of knowing, recognizing, or being aware of, and the character 别, which introduces the crucial action of distinguishing, differentiating, or separating one thing from another. Together, they do not merely add meanings but fuse into a single, more specific concept. This fusion describes the complete intellectual process of actively discerning and assigning identity, first by perceiving or acknowledging something (识), and then by analytically setting it apart from other similar things to correctly classify it (别). Thus, the compound encapsulates the entire action of identification or recognition as a unified act of perceptive differentiation.
