Melancholia (from Greek μελαγχολία - melancholia "sadness, lit. black bile"), also lugubriousness, from the Latin lugere, to mourn; moroseness, from the Latin morosus, self-willed, fastidious habit; wistfulness, from old English wist: intent, or saturnine, (see Saturn), in contemporary usage, is a mood disorder of non-specific depression, characterized by low levels of enthusiasm and eagerness for activity.
In a modern context, "melancholy" applies only to the mental or emotional symptoms of depression or despondency; historically, "melancholia" could be physical as well as mental, and melancholic conditions were classified as such by their common cause rather than by their properties.
