Ologies & -Isms
Ologies & Isms is a guide to every academic study, discipline, and theory you might ever need to know.
Ology is a suffix derived from the Greek word that means knowledge. It refers to the "study of". From biology (the study of physical life) to melissopalynology (the study of honey) to scelerology (the study of the outer coat of the eye ball), there are more ologies in the English language than you ever thought possible.
Isms refer to doctrines, conditions or characteristics. Relativism, for example, is the idea that everything is relative, while socialism, communism, and capitalism all refer to different theories of government.
The Ologies & Isms dictionary also contains definitions of words ending in graphy (a suffix relating to a field of study), -metry (the science of measuring), - philia (a suffix used in science to refer to attraction), and -mancy (a suffix related to the study of religion).
