An adjective is a word that describes or modifies a noun or pronoun. It provides additional information about the qualities, characteristics, or attributes of the noun it accompanies. For example, in the phrase "the tall building," the word "tall" is an adjective because it describes the building's height. Adjectives can be used to express qualities independently or in comparison to others, and they often appear directly before the noun or pronoun they modify. They can also follow a linking verb to describe the subject of a sentence, such as in "The dog is happy." There are different forms of adjectives:

• Absolute adjectives describe a quality without comparison (e.g., "dead," "unique").
• Comparative adjectives compare two things (e.g., "taller," "more beautiful").
• Superlative adjectives indicate the highest or lowest degree of a quality (e.g., "tallest," "most beautiful").

Adjectives can describe things like size, color, shape, emotion, quantity, and more, enriching the meaning of the nouns they modify. In short, adjectives answer the questions "What kind?" "Which one?" or "How many?" about a noun or pronoun. Examples include words like "big," "yellow," "fun," and "fast".
