Adjectives are words that describe or modify nouns, giving us more information about them. For example, in the phrase “the blue sky,” the adjective “blue” tells us what color the sky is. Adjectives can describe qualities, quantities, or states, helping us paint a clearer picture in our minds. They can be used in various ways, such as in comparisons. For instance, we can say “John is taller than Mike” to compare their heights. Adjectives can also be used in different forms, like “happy,” “happier,” and “happiest,” to show varying degrees of a quality.
