noun
condition of health; state of health
Formal, somewhat literary term for one's health status. Often used in written correspondence or official contexts to inquire about or report on well-being.
時候の挨拶に続けて、相手の健否を尋ねる文面が定型となっている。
Following seasonal greetings, it is customary to include a phrase asking about the recipient's health.
Compound of 健 (health, strength) and 否 (negation, condition), literally 'healthy or not', referring to the state of one's health. The exact historical derivation is uncertain, but it follows a classical Chinese pattern of forming abstract nouns.
