Denominal eponyms in English medical terminology: suffixation

Medical terminology is characterised by various eponyms firmly rooted in the language of medicine. Such eponyms and eponymous terms are mainly created from the surnames of doctors or researchers. Today, there are no clear rules for the formation of eponymous terms, and this method of naming is somewhat random due to a number of extra- and intra-linguistic factors. However, when eponyms are widely recognised, they become common nouns and can form derivatives that adhere to some morphological rules.
