The Challenge:
* Self-Describing Words: These usually refer to words that describe themselves, like "short" (a short word), "unbreakable" (an unbreakable word).
* "X" is Rare: The letter "x" is not commonly used at the beginning of words in English. This limits the possibilities.
Options:
* X-Rated: This is a self-describing term, as it refers to material deemed unsuitable for viewing by those under a certain age. However, it's not a typical self-describing word in the sense of the structure of the word itself.
* Xerographic: This describes the process of xerography, which is a photocopying method. While not technically self-describing, it does describe the process of making copies.
* You Could Create One! You could invent a word like "X-word" to describe itself. It's not a real word, but it's a fun example of self-description.
