An adjective is a word that describes or modifies a noun, giving us more information about it. For example, in the phrase “the blue sky,” the adjective “blue” tells us what kind of sky we are talking about. Adjectives can describe qualities, quantities, or states, helping us to create a clearer picture in our minds. Adjectives can be used in different forms, such as comparative and superlative. For instance, we can say “tall” for one person, “taller” when comparing two people, and “tallest” when talking about three or more. This helps us understand the differences between things more easily.
