What does "-logy" refer to in medical terms?

The suffix "-logy" is derived from the Greek word "logia," which means "study of" or "science." In medical terms, it refers to the process of studying a particular subject or field. For example, "biology" is the study of living organisms, and "pathology" is the study of diseases. Hence, when "-logy" appears in a medical term, it indicates an area of systematic study or a body of knowledge regarding that specific focus. This understanding illustrates the breadth of research and inquiry represented by medical terms that include this suffix.
