- n. Synonyms Illness, Sickness, Ailment, complaint, disorder. Sick and sickness have been considered until within the present century essentially synonymous with ill and illness. Of late, English usage has tended to restrict sick and sickness to nausea, and American usage has followed it so far as to regard illness as a rather more elegant and less definite term: beyond that it does not seem likely to go. An ailment is generally of small account, comparatively, and local: as, his ailment was only a headache. None of these words represent ordinarily so serious an attack as disease, but illness and sickness may do so. See disease and debility.
