Define Fallacy of redundant definition.

The fallacy of redundant definition, also known as the fallacy of tautology, occurs when a definition includes unnecessary or repetitive elements, adding no informative content to the term being defined. In essence, it involves restating the meaning of a term in a way that contributes no new understanding or clarification.

For example, if one defines a "bachelor" as an "unmarried man," it is considered a redundant definition because the term "unmarried" is already inherent in the concept of being a "bachelor." The addition of "unmarried" does not provide any new information but merely repeats what is already implicit in the term.

This fallacy can lead to confusion or create the illusion of depth in an argument while failing to contribute substantive content. Effective definitions should aim to convey precise and meaningful information without unnecessary repetition. Recognizing and avoiding the fallacy of redundant definition is essential for maintaining clarity and logical rigor in both everyday discourse and more formal argumentation.
