The rule that proper nouns become adjectives when they describe nouns defines which grammatical category?

• A. Adjectives
• B. Proper adjectives
• C. Nouns
• D. Verbs

Answer: (B)

When a proper noun describes another noun, that word functions as an adjective. This category is called proper adjectives. For example, from a place or person name we get words like American, French, or Shakespearean, which describe the nouns that follow: American car, French cheese, Shakespearean play. These are adjectives formed from proper nouns, setting them apart from ordinary adjectives that don’t originate from a specific name.
