The word "演唱" is formed by combining two independent characters, each conveying a core action, to create a new, unified concept. The first character, "演" (yǎn), carries the meaning of to perform, to act, or to exhibit. The second, "唱" (chàng), specifically means to sing. When joined, they do not simply list two separate acts; instead, they conceptually fuse to define the particular act of delivering a song in a performed, often public, manner, encapsulating the full artistic presentation of singing with expression, technique, and stage presence. It is the synthesis of performance and vocalization into a single activity.
