Translation guide
The English word "basis" refers to the foundation, starting point, or underlying principle of something. In Japanese, the most common equivalent is 基盤 (kiban) for abstract foundations, 基礎 (kiso) for fundamentals, and 根拠 (konkyo) for grounds or evidence. The choice depends on whether you mean a conceptual base, a fundamental principle, or a reason for something.
