The word 无知 is formed through a direct and intuitive conceptual combination: the first character 无 (wú) means "without" or "to lack", and the second character 知 (zhī) means "knowledge" or "awareness". By placing them together, the concept of "without knowledge" is created, naturally arriving at the meaning of "ignorance". This formation is not a grammatical rule but a foundational method of Chinese thought, where combining core ideas produces a new, unified concept that describes a state of being or condition, in this case, the state of lacking understanding or awareness.
