An intense and excessive love for one's country, often to the point of being overly nationalistic.
His superpatriotism made him blind to the flaws in his country's policies.
Superpatriotism → It is formed from "super-" (meaning above or beyond) and "patriotism" (from "patriota" in Latin, meaning a fellow countryman or patriot). The word "superpatriotism" refers to an extreme or excessive form of patriotism that goes beyond normal loyalty to one's country.
Think of being 'above' ('super-') regular love for your country ('patriotism') — that's why superpatriotism means an extreme love for one's country.
