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.
