What is the function of an adjective in a sentence?

An adjective serves the function of providing more information about a noun, which is why describing a noun is the correct understanding of its role in a sentence. By adding details such as color, size, shape, or quantity, adjectives enhance the information provided about the noun, allowing for clearer and more vivid communication. For instance, in the phrase "the tall building," the adjective "tall" gives us a specific idea about the building's height, enriching the reader's understanding of what is being discussed. This makes adjectives essential in forming descriptive and detailed sentences, which engage readers and convey more precise meanings.
