The word 无辜 is formed through a direct and intuitive conceptual blending of its two components: 无, meaning "without" or "lack of", and 辜, an ancient term for "crime" or "guilt". By placing them together, the meaning visually and logically unfolds from "without crime" to express the broader, more abstract state of "innocence" or "being wronged", capturing the essence of a blameless condition. It is a straightforward fusion where the first character negates the specific fault named by the second, creating a new, unified idea.
