      Medical Terminology

      Medical Terminology often uses words created using prefixes and suffixes in Latin and Ancient Greek. In medicine, their meanings, and their etymology, are informed by the language of origin. Prefixes and suffixes, primarily in Greek—but also in Latin, have a dropable -o-. Medical roots generally go together according to language: Greek prefixes go with Greek suffixes and Latin Prefixes with Latin Suffixes.
