Etymology
Origin of ideology
Explanation
An ideology is a set of opinions or beliefs of a group or an individual. Very often ideology refers to a set of political beliefs or a set of ideas that characterize a particular culture. Capitalism, communism, socialism, and Marxism are ideologies. But not all -ism words are. Think: cronyism (a system of graft whereby friends unfairly help each other make money.) Our English noun is from French idéologie. The suffix –logy, used with many English words describing theories or doctrines, is from Greek logos "word, reason, speech, account."
