In everyday reasoning, the fallacy of four terms occurs most frequently by equivocation: using the same word or phrase but with a different meaning each time, creating a fourth term even though only three distinct words are used. The resulting argument sounds like the (valid) first example above, but is in fact structured like the invalid ...
Equivocation in a syllogism (a chain of reasoning) produces a fallacy of four terms (quaternio terminorum). Below is an example: Since only man [human] is rational. And no woman is a man [male].

Attacking Faulty Reasoning: A Practical Guide to Fallacy-free Arguments [1] is a textbook on logical fallacies by T.
