What is the adjective of adjective?

This is a bit of a trick question! There isn't a single word that acts as the adjective of "adjective" in the same way that "beautiful" is the adjective of "beauty".

Here's why:

* Adjectives describe nouns. "Adjective" itself is a noun, not something you can directly describe with another adjective.

* You can use phrases to describe adjectives. For example, you could say "very descriptive adjective" or "highly specific adjective".

So, while there isn't a single word, you can use other words and phrases to describe the qualities of an adjective itself.
