The word "pathology" entered English in the 1610s from the French "pathologie," derived from the Greek "pathologia," combining "pathos" (suffering, disease, feeling) and "logia" (study of).

By the late 1800s, with the invention of the microscope and new laboratory methods, pathology became a distinct medical specialty, and in the 20th century, the term expanded beyond medicine to describe any kind of dysfunction, such as in "social pathology" or patterns of compulsive behavior.
