There are different types of adjectives, such as descriptive, quantitative, possessive, demonstrative, and interrogative adjectives. Descriptive adjectives describe the qualities of a noun, quantitative adjectives show the quantity or amount of a noun, possessive adjectives show ownership of a noun, demonstrative adjectives point out specific nouns, and interrogative adjectives are used in questions to ask for more information about a noun.

Adjectives can be used to compare nouns in three degrees: positive, comparative, and superlative. The positive degree describes a noun without making any comparison, the comparative degree compares two nouns showing that one has more or less of a certain quality than the other, and the superlative degree compares three or more nouns showing which has the most or least of a certain quality.

To form comparative and superlative adjectives, we can use different methods depending on the adjective. For one-syllable adjectives, we add “er” to form the comparative degree and “est” to form the superlative degree. For two-syllable adjectives ending in “y,” we change the “y” to “ier” to form the comparative degree and to “iest” to form the superlative degree. For other adjectives, we use the words “more” or “most” before the adjective to form the comparative and superlative degrees. Some adjectives have irregular comparative and superlative forms, such as “good/better/best,” “bad/worse/worst,” and “far/farther (or further)/farthest (or furthest).”

In sentences, adjectives usually come before the noun they describe, and when using multiple adjectives, there is a specific order to follow: opinion, size, shape, age, color, origin, material, and purpose. Linking verbs can also be used to connect the subject of the sentence to an adjective that describes it, such as “be,” “seem,” “appear,” “look,” “feel,” “sound,” “taste,” “smell,” “become,” and “get.” Remember that adjectives don’t change their form when used with linking verbs.
