The document defines and provides examples of different types of adjectives:
- Nouns used as adjectives come before another noun and answer questions like "what kind" or "which one". Examples include "snack food" and "ring finger".
- Proper adjectives are formed from proper nouns, like "Bostonian" and "Indian".
- Compound adjectives are made of multiple words, either hyphenated like "long-distance" or combined like "bedtime".
- Possessive nouns can function as possessive adjectives when modifying another noun, as in "the animal's fur" and "Chicago's skyscrapers".
