Politics
The word comes from the same Greek word from which the title of Aristotle's book "Politics" (Πολιτικά, "Polis") also derives; "polis" means "affairs of the cities". The book title was rendered in Early Modern English in the mid-15th century as "Polettiques"; it became "politics" in Modern English. The singular "politic" first attested in English 1430 and comes from Middle French "politique", in turn from Latin "politicus", which is the Latinization of the Greek πολιτικός ("politikos"), meaning amongst others "of, for, or relating to citizens", "civil", "civic", "belonging to the state", in turn from πολίτης ("polites"), "citizen" and that from πόλις ("polis"), "city".
Ideology
In social studies, a political ideology is a certain ethical set of ideals, principles, doctrines, myths, or symbols of a social movement, institution, class, or large group that explains how society should work, and offers some political and cultural blueprint for a certain social order. Political ideologies are concerned with many different aspects of a society, including (for example): the economy, education, health care, labor law, criminal law, the justice system, the provision of social security and social welfare, trade, the environment, minors, immigration, race, use of the military, patriotism, and established religion.
