The word 描述 is formed by combining two individual characters, each contributing a layer of meaning to create a new, composite concept. The first character, 描 (miáo), carries the core idea of tracing, sketching, or outlining a form. The second character, 述 (shù), introduces the idea of narrating, stating, or recounting in words. Together, they merge the acts of visually outlining and verbally narrating into a single integrated concept meaning "to describe", capturing both the structural and explanatory dimensions of the act.
