I kind of have my own, idiosyncratic way of defining these things.
Communism: state/centralized or decentralized democratic and egalitarian control of housing.
Syndicalism: state/centralized or decentralized democratic and egalitarian control of industry and commerce.
Socialism: state/centralized democratic and egalitarian control of money and resources generated from industry and commerce.
Capitalism, meaning 1: decentralized oligarchic and/or dictatorial and elitist control of housing, industry and/or commerce.
Capitalism, meaning 2: a partly free market with the four monopolies in place.

Corporatism: state/centralized oligarchic and/or dictatorial and elitist control of housing, industry, commerce, wealth and/or resources generated from industry and commerce.
Corporatism can take three major forms: corporations running the state for their own benefit, as they do in America, or the state running corporations for its own benefit, not for the benefit of the people, as they do in Russia, or a synthesis of the former and the latter, as they did in Nazi Germany and Fascist Italy.
Fascism: national corporatism and authoritarianism (authoritarianism: government gets involved in your personal life).
Nazism: racial fascism.
Zionism: Jewish racial fascism.
Individualism, meaning 1: self-employment, small business.
Individualism, meaning 2: a fully free market without the four monopolies in place.
