also: りんせい
noun
innate nature; disposition; character
Literary term for one's inherent nature or disposition. Rare in modern Japanese; more common synonyms are 性質, 性格, or 天性.
彼の禀性は穏やかだ。
His innate nature is gentle.
古典では「禀性」が人の生まれつきの性質を指すことがある。
In classical texts, 禀性 can refer to a person's inborn disposition.
The exact derivation is uncertain; the kanji 禀 (receive, innate) and 性 (nature) combine to suggest 'inborn character'. The word is rare and literary.
