pathological

diseased / abnormal / compulsive / obsessive
Adjective

This term operates in two distinct spheres: the clinical and the behavioral. In a medical context, it describes physical manifestations of disease or abnormal tissue changes that deviate from a healthy state. It is a neutral, descriptive term used by practitioners to categorize biological dysfunction. When applied to behavior, the word takes on a more judgmental and psychological tone. It describes actions, such as lying or gambling, that are driven by an uncontrollable internal compulsion rather than a conscious choice or a specific external motive. In this sense, it implies a deep-seated dysfunction of the personality.
