What are the differences among Marxism, Socialism and Communism?

[Ellie]

Marxism and communism are both forms of socialism, and technically one could say communism is a form of Marxism/Marxism is a form of communism. Marxism is a method of analysis, a theory. Communism is the actual practice of the ideas of Karl Marx and Friedrich Engels.

So technically they aren't "different", so much as socialism is the general category for all three, and then Marxism is the theoretical side to Marx's ideas and communism is Marxism in practice.

This is a rather simplified explanation to a very complex question. I assumed you have basic knowledge of what the three economic systems are. Hope this helps!
