This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymology. There are a few rules when using medical roots. Firstly, prefixes and suffixes, primarily in Greek, but also in Latin, have a droppable -o-. As a general rule, this -o- almost always acts as a joint-stem to connect two consonantal roots, e.g. arthr- + -o- + logy = arthrology. But generally, the -o- is dropped when connecting to a vowel-stem; e.g. arthr- + itis = arthritis, instead of arthr-o-itis. Secondly, medical roots generally go together according to language: Greek prefixes go with Greek suffixes and Latin prefixes with Latin suffixes. Although it is technically considered acceptable to create hybrid words, it is strongly preferred to not mix different lingual roots.
