Adjectives are words that describe or modify nouns and pronouns, providing more detail and specificity to them. They can describe qualities such as size, color, shape, and quantity, or convey an opinion or a condition. For example, in the phrase “a tall building,” the adjective “tall” describes the height of the building. Adjectives help to create clearer and more vivid pictures in the reader’s or listener’s mind, enriching language by adding depth and precision. They can also compare nouns, as in “bigger” or “most beautiful,” which are comparative and superlative forms of adjectives.
