Adjectives describe nouns. They give information about qualities, size, age, color, shape, condition, and appearance. In a tall tree, tall tells the size of the tree. In a red bag, red tells the color. In an old house, old tells the age. Without an adjective, the noun is more general. House names a thing, but old house gives a clearer picture. Adjectives can also describe how something feels or seems, as in a noisy street, a clean shirt, or a happy child.

In a simple noun phrase, an adjective usually comes before the noun. The pattern is adjective + noun. We say a small room, an expensive phone, and three careful workers. The adjective makes the noun more specific by showing what kind of thing it is. In English, this position is common and natural in everyday speech and writing. When more than one adjective appears before the noun, they all stay before it, as in a large black suitcase.

Adjectives before nouns in simple phrases

Usage	Explanation
Basic description	Use adjectives before a noun when you want to make the noun more specific and give basic description.
Size and age	Use adjectives before a noun to show size or age when those details help identify the noun.
Opinion and quality	Use adjectives before a noun when you want to share an opinion or quality about it.

Adjectives also come after linking verbs such as be, seem, feel, look, sound, and become. In this pattern, the adjective describes the subject. We say The soup is hot, She seems tired, and The room feels cold. The verb does not show an action here. It connects the subject to a word that tells what the subject is like. After a linking verb, the adjective stays in its base form: The apples are fresh, not freshly.

Adjectives after linking verbs

Usage	Explanation
Subject description	Use an adjective after a linking verb like be when it describes the subject.
Seeming state	Use an adjective after seem when you want to describe how something appears.
Feeling state	Use an adjective after feel when you want to describe a feeling or condition.

English adjectives usually do not change for number or gender. The same form works with singular and plural nouns: a new car, new cars. The same form also works with masculine and feminine nouns: a kind man, a kind woman. The adjective stays the same whether the noun is one thing or many things, or whether it names a man or a woman. Nouns may change, but the adjective usually does not.

Adjective forms that stay the same

Idea
An English adjective usually does not change for singular or plural nouns.
An English adjective usually does not change for masculine or feminine nouns.
The adjective form stays the same even when the noun changes in number or gender.

When several adjectives come before a noun, English usually follows a common order. General opinion comes first, then size, age, shape, color, origin, and material. We say a beautiful small old round blue Italian wooden table. Speakers usually use only a few adjectives, but the order still matters. Adjectives that describe the same level of importance can be separated by commas, as in a calm, quiet street. When one adjective directly describes the noun more closely than the others, no comma is used: a large black dog.

Common order for multiple adjectives

Idea
Opinion usually comes before size when two adjectives both describe one noun.
Size usually comes before color in a common adjective order.
Coordinate adjectives can use commas when each adjective gives separate equal description.

Some adjectives normally come before a noun and sound unnatural after a linking verb. Others normally come after a linking verb and are rare before a noun. We say a main road, but not usually the road is main. We say the baby is asleep, but not usually an asleep baby. Some adjectives change meaning with position. A responsible person means a person who can be trusted, while The person responsible means the person who did it. A concerned mother usually means worried, while The mother is concerned often means worried about something specific.

Adjectives with special positions and meanings

Idea
Some adjectives usually come only before nouns in standard English.
Some adjectives usually come after linking verbs rather than before nouns.
Some adjectives can change meaning by position in the sentence.

Adjectives can describe pronouns after linking verbs. In speech, this is common with pronouns such as I, you, he, she, we, they, and it. We say I am ready, She is busy, They are lucky, and It seems strange. The adjective follows the verb and describes the pronoun as the subject. In informal English, this pattern is especially common in short answers such as I’m fine and We’re okay.

Adjectives describing pronouns in speech

Usage	Explanation
After be with pronouns	Use an adjective after a linking verb to describe a pronoun in everyday speech.
Informal short reply	Use an adjective alone in informal conversation when the meaning is clear from the situation.
Feeling words with pronouns	Use an adjective after a linking verb to describe how a pronoun feels or seems.

Adjectives can show comparison. The comparative form compares two people, things, or groups. The superlative form shows the highest or lowest degree in a group of three or more. We say taller, more careful, the tallest, and the most careful. Short adjectives often add -er and -est: small, smaller, smallest. Longer adjectives usually use more and most: interesting, more interesting, most interesting. These forms work in patterns like A is taller than B and C is the tallest in the class.

Comparative and superlative adjective forms

Idea
Use the comparative form to compare two people or things.
Use the superlative form to show the highest degree in a group.
Use more and most with longer adjectives in many common cases.

Some words can work as adjectives or adverbs depending on where they appear. Fast is an adjective in a fast train and an adverb in The train moves fast. Hard is an adjective in a hard chair and an adverb in She works hard. Light is an adjective in a light jacket and can also appear in other ways depending on the sentence. The form alone does not decide the part of speech. The position and the word it describes show the function.
