The compound word "逃逸" is formed by combining two semantically related characters: "逃" (táo), which means "to flee" or "to escape", and "逸" (yì), which means "to flee", "to be lost", or "to be at leisure". Together, they create a synergistic meaning that intensifies the concept of fleeing, specifically implying a swift, often illicit or irresponsible, escape from a scene or responsibility. This formation follows a common pattern in Chinese morphology where two near-synonyms are paired to form a single, more precise or formal term, with "逃逸" frequently used in legal and technical contexts such as "hit-and-run" (肇事逃逸) or "escape velocity" (逃逸速度).
