How to Understand
已知
已知 means 'known' or 'a known fact.' It refers to something that is already understood, established, or recognized as true. Unlike similar terms like 'known,' it often implies a formal or factual status rather than personal knowledge.
The character 已 (yǐ) originally meant 'already' or 'finished,' and 知 (zhī) means 'to know' or 'knowledge.' Together, they form a term that emphasizes something that has been confirmed or is widely accepted.
已知 is commonly used in academic, legal, or technical contexts where accuracy and established facts are important. It appears frequently in research papers, official documents, and logical discussions to indicate information that is already established.
