Is at the end of the word to add meaning, such as condition, disease, or procedure.
Every medical term must have a suffix.
For example, the suffix -itis, which means inflammation, when added to cardi- forms the new word carditis, which means inflammation of the heart. The majority of the time, the suffix is added to a word root, as in carditis above. However, terms can also be built from a suffix added directly to a prefix, without a word root. For example, the term dystrophy, which means abnormal development, is built from the prefix dys- and the suffix -trophy (meaning development).
