Etymology : Malaise, whose Old French ancestor was formed from the combination of mal (“bad”) and aise (“comfort”), has been a part of English since the mid-18th century. It originally referred to a vague feeling of weakness or discomfort accompanying the onset of an illness—a meaning still in use today when a virus or other malady starts producing symptoms—but has since broadened to cover a general, ominous sense of mental or moral ill-being.
