What Are Adjectives?

Adjectives are words that describe or modify nouns and pronouns, providing more information about their qualities, quantities, or states. They help make sentences more specific and vivid by answering questions like “What kind?”, “How many?”, or “Which one?” For example, in the phrase “a red apple,” the word “red” is an adjective that tells us the color of the apple. Adjectives can appear before the noun they describe (e.g., “a tall building”) or after linking verbs (e.g., “The sky is blue”). Overall, adjectives enrich language by adding detail and depth to descriptions.
