Suppose you seperated all the adjectives of the English language into two groups, those that were self-descriptive and those that were not. Words like "pentasyllabic", "awkwardnessful", and "short" would fall into the first category, while words like "bisyllabic", "long", "edible", and "hyphenated" would fall into the second. To which class would the word "non-self-descriptive" belong? If you don't like hyphens, try it with heterological, it means the same thing.
