11. Synonyms Sick. Ill, Ailing, Unwell, Diseased, Morbid, Sickly. Sick and ill are general words for being positively out of a healthy state, as ailing and unwell are in some sense negative and therefore weaker words for the same thing. There has been some tendency in England to confine sick to the distinctive sense of ‘nauseated,’ but in America the word has continued to have its original breadth of meaning, as found in the Bible and in Shakspere. Diseased follows the tendency of disease to be specific, as in diseased lungs, or a diseased leg—that is, lungs or a leg affected by a certain disease; but the word may be used in a general way. Morbid is a more technical or professional term, indicating that which is not healthy or does not act in a healthy way; the word is also the one most freely used in figurative senses: as, morbid sensitiveness, self-consciousness, or irritability. Sick and ill apply to a state presumably temporary, however severe; sickly indicates a state not quite equal to sickness, but more permanent, because of an underlying lack of constitutional vigor. See illness, debility, disease.
