Adjectives are words that describe or modify nouns or pronouns. They provide more information about the person, place, thing, or idea being talked about.

For example, in the sentence The happy dog chased the ball, the adjective happy describes the dog and tells us more about its state of mind. Similarly, in the sentence She wore a beautiful dress, the adjective beautiful describes the dress and tells us more about the way it looks.

Adjectives can come before or after the noun they describe, depending on the sentence structure. Some common examples of adjectives include colours red, blue, sizes big, small, shapes round, square and qualities happy, sad.

By using adjectives, we can add detail and description to our sentences, making our writing more interesting and engaging.
