feeling ill; sensation of illness
Archaic noun for the subjective feeling or signs of being unwell. Not used in modern Japanese; the modern equivalent is 病気 (びょうき) or 気分が悪い.
In old documents, the word やまいけ appears as a term for the feeling or signs of illness.
Compound of 病 (yamai, 'illness') and 気 (ke, 'feeling, sign'). The exact historical development is uncertain, but it likely referred to the subjective sensation of being unwell.
