Adjectives are descriptive words that modify nouns or pronouns to make them more distinct. Adjectives answer the questions "Which one?" "What kind?" "How many?" "Whose?"
•Examples: Here is a list of nouns without adjectives: tree, bird, car, chair, dog.
By adding adjectives, you make the nouns specific
•Example: the large walnut tree; the green and white bird; the fastest car; the
seven Adirondack chairs; the sleeping dog; Fred's house
All of these examples are adjectives. They describe the nouns more
completely.
Notice Adirondack chair. Sometimes proper nouns can be used as adjectives. If you’re unsure, ask what kind of chair it is. Answer: an adjective, whether it is a green chair, a hard chair, a comfortable chair, an Adirondack chair, President Lincoln’s chair. All of these words describe what kind of chair it is; therefore, they are adjectives.
Notice too the sleeping dog. Sleeping is a verb form, but since it describes what kind of dog, sleeping is an adjective. There are verb forms that act as adjectives called Participles. Go to the section on Verbals to see more.
