蓋然性

1. Origins, structure, and basic meaning

• Structure: In 蓋然性 (がいぜんせい), plausibility 蓋然 and quality 性 combine to denote probability.
• Basic usage: 蓋然性 is the degree to which a judgment or event appears likely or plausible.

2. Common pitfalls and similar expressions

• Probability versus certainty
  • It indicates possibility rather than certainty, and a predicate after 蓋然性が states how high or low it is.
