The compound word "隐身" is formed through a logical semantic combination of its two morphemes: "隐" (yǐn), meaning "to hide" or "conceal," and "身" (shēn), meaning "body" or "self." Together, they create a verb-object structure where the action of hiding is directly applied to the physical self, thus literally meaning "to hide the body." This term originates from classical Chinese lore and Daoist concepts describing the ability to become invisible. In modern usage, it has been metaphorically extended to digital contexts, such as "隐身模式" (stealth mode) or "隐身在线" (invisible online), maintaining the core idea of making one's presence undetectable.
