    To know whether a word X is heterological, we must already know what X means. (By contrast, I can know that the word “subdermatoglyphic” has certain syntactic properties—it is six-syllabled, contains the letter “m”, etc.— without having any idea of its meaning.) This indirectness is fine as long as X already has an assigned meaning, for in that case the meaning of “heterological” is ultimately grounded. But when X is the word “heterological”, then we are trying to define “heterological” in terms of itself. We have a closed circle, and a contradictory one, due to the negation operator in the definition.

Proper noun

  1. A placeholder for an unknown, suppressed or hypothetical name.

    Examples

    The woman known until now as Witness X has been unmasked after a court ruling.

    Suppose that Mr and Mrs X have been married for many years.

    Although the Take Care Clause grants the president significant authority to enforce the laws, the duty to take care does not include a power to forbid the execution of the laws. Consequently, the president does not have the authority to disregard Congress’s declaration of war against Country X. On the contrary, the president has an obligation to faithfully execute the declaration of war, even against their own beliefs and wishes.

  2. A surname, used by those who have had their identity or heritage, including their proper ancestral names, erased or forgotten.
