Meaning and Usage
"根拠" (こんきょ) means "basis" or "foundation" and is often used to refer to the evidence or grounds supporting a statement, claim, or theory. It is a formal noun commonly used in academic, legal, and everyday contexts when discussing reasons or proof.

Usage Notes
When using 根拠, speakers imply that there is a rational or factual foundation behind what is being said. It is often contrasted with opinions or rumors that lack such support. This word is formal and appropriate in written and spoken Japanese when discussing evidence or justification.
Common Mistakes
Learners sometimes confuse 根拠 with 理由 (reason). While 理由 explains why something happens or is done, 根拠 specifically refers to the evidence or grounds that justify a claim or belief. To avoid confusion, use 根拠 when emphasizing proof or factual support.
