* "Pathos" means "suffering" or "disease."
* "Logos" means "study" or "science."
Therefore, "pathology" literally means "the study of suffering" or "the science of disease."
The word was first used in the 17th century, but its meaning has evolved over time. Originally, it referred to the study of the symptoms and course of disease. Today, pathology is a much broader field that encompasses the study of the causes, mechanisms, and development of disease, as well as the changes that occur in the body as a result of disease.
