What are the components of medical words in medical terminology?

• Answer:

  prefix, root, and suffix. The field of medicine deals with Greek and Latin-derived terms and codes that seem esoteric for most people. However, learning a little bit about the meaning of the Germanic and Romatic suffixes or prefixes of these terms can give you instant insight on their corresponding meaning and the purpose behind their naming. It can even help you predict what similar words mean. For example, hepatitis, which derives itself from the Greek word "hepar" originally, relates to the concept of "pleasure", according to the Journal of Hepatology, the official journal of the European Association for the Study of the Liver. That was because the liver was believed to be the "seat of soul and human feelings" in ancient times.
