List of medical roots, suffixes and prefixes

This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymology. Most of them are combining forms in New Latin and hence international scientific vocabulary. There are a few general rules about how they combine. First, prefixes and suffixes, most of which are derived from ancient Greek or classical 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- + = arthritis, instead of *arthr-o-itis. Second, medical roots generally go together according to language, i.e., Greek prefixes occur with Greek suffixes and Latin prefixes with Latin suffixes. Although international scientific vocabulary is not stringent about segregating combining forms of different languages, it is advisable when coining new words not to mix different lingual roots.

The following is an alphabetical list of medical prefixes and suffixes, along with their meanings, origin, and English examples.

This section contains lists of different root classification (e.g. body components, quantity, description, etc.). Each list is alphabetized by English meanings, with the corresponding Greek and Latin roots given.
