Ambiguity is just a long, fancy word for confusion. Fallacies of ambiguity are arguments that are faulty because they use words or phrases that are unclear or have more than one meaning.

Among the fallacies of ambiguity are: equivocation, amphiboly, accent, reification, composition, and division.

But we will only cover the two most common types, but least recognized. Equivocation and reification. The other types are rather obvious, I'll leave the research up to you.
