Adjectives describe nouns and other adjectives -- brown puppy or chocolate brown puppy. They show what kind, how many, and which one. Adjectives must be placed near the words they modify. They may come before the word they describe -- a cute puppy -- or they may follow the word they describe -- the puppy is cute.
Comparatives compare two things connected with "than" or "but." Examples:
- Steve is older than Carl.
- Steve is older, but Carl is taller.
Note: When using pronouns, the subject form of the pronoun always follows "than." Example:
- Steve is older than I [am].
Superlatives compare more than two things and usually use "the" because only one element is the superlative. Examples:
- Sears Tower in Chicago is the tallest building in North America.
- The Empire State Building in New York is tall, but the Sears Tower in Chicago is taller. Taipei 101 in Taiwan is the tallest building in the world.
