The job of an adjective is to give more information about a noun. A noun is a person, object, animal, or idea. An adjective will describe the noun by giving its size, composition, color, age, shape, weight, etc. Adjectives can be a single word or a group of words and can also be used with a verb, like “is” or “was.” Most adjectives come before the noun they modify.
Examples of adjectives before nouns include: “I saw a really big dog.” or “That crazy cat is running around in circles.” Examples of adjectives used with verbs are: “My friend is adorable.” and “That house is huge.” Understanding the function of an adjective helps to answer the question, “What is a superlative adjective?”
