"Isms" are distinctive doctrines, systems, or theories, and in the art world they typically signify art movements or styles. The suffix (word fragment added at the end of a word to modify its meaning) "-ism" marks a word as one signifying a doctrine, theory, or system of principles; or an attitude strongly in favor of or against a given group; a distinctive or characteristic trait; an action, process, or practice; a characteristic behavior or quality; a state or condition resulting from an excess of something specified.
