Parts of Speech: Adjectives
An adjective is a word that describes or modifies a noun or pronoun, telling us what kind, how many, or which one. Words like big, red, happy, and fast are all adjectives. This guide covers where adjectives go in a sentence, the comparison rules that trip people up most, and how to tell an adjective apart from an adverb.
What Is an Adjective?
An adjective gives more information about a noun or pronoun. It can describe size, color, shape, quantity, or quality.
Where Adjectives Go in a Sentence
Adjectives can sit in two different positions, and knowing both helps you spot them even when they're not right next to the noun.
- Attributive adjectives sit directly before the noun they describe: "The tall building."
- Predicative adjectives follow a linking verb like is, seem, or feel, connecting back to the subject: "The building is tall."
Most adjectives work in both positions, but a few don't. Main only works attributively ("the main reason", never "the reason is main"), while asleep only works predicatively ("the man is asleep", never "the asleep man").
Comparative & Superlative Adjectives
Adjectives change form to show comparison, and this is where most real mistakes happen.
- Absolute: describes one thing on its own (tall, happy, expensive).
- Comparative: compares two things (taller, happier, more expensive).
- Superlative: compares three or more things, showing the highest degree (tallest, happiest, most expensive).
Formation rules:
| Adjective Length | Comparative | Superlative |
|---|---|---|
| One syllable | add -er (tall → taller) | add -est (tall → tallest) |
| Two syllables ending in -y | replace -y with -ier (happy → happier) | replace -y with -iest (happy → happiest) |
| Two or more syllables (most others) | use more (careful → more careful) | use most (careful → most careful) |
Irregular comparatives and superlatives don't follow any pattern and have to be memorized:
| Absolute | Comparative | Superlative |
|---|---|---|
| good | better | best |
| bad | worse | worst |
| far | farther / further | farthest / furthest |
| little | less | least |
| many / much | more | most |
The Order of Multiple Adjectives
When you stack more than one adjective before a noun, English speakers follow an order almost automatically, even without knowing the rule:
"A lovely (opinion) small (size) old (age) round (shape) brown (color) French (origin) wooden (material) table."
Breaking this order, even while keeping every word grammatically correct, is what makes a phrase sound subtly "off" to a native speaker.
Types of Adjectives
Beyond the basic descriptive adjective, English has several specialized types worth recognizing.
Describe a quality or characteristic. These are the main words used to describe appearance or personality.
Describe an amount, number, or quantity of a noun.
Point directly to a specific noun (used right before a noun).
Show ownership or relationship to a noun.
Formed from a proper noun and are always capitalized.
Look like a verb's -ing or -ed form but function entirely as an adjective.
Compound Adjectives
A compound adjective combines two or more words to act as a single descriptor. The hyphenation rule depends on position:
- Before the noun: hyphenate — "A well-known author."
- After the noun: usually no hyphen — "The author is well known."
- Adverb ending in -ly + adjective: never hyphenate, regardless of position — "A highly respected official."
Adjectives vs. Adverbs
This is the mistake even confident speakers make. Adjectives modify nouns and pronouns; adverbs modify verbs, adjectives, and other adverbs. The confusion usually shows up with linking verbs.
How to Identify an Adjective?
If you're unsure whether a word is an adjective, check these signals:
- Does it describe a noun or pronoun? If it answers what kind, how many, or which one, it's likely an adjective.
- Does it follow a linking verb? Words after is, seem, feel, become that describe the subject are predicative adjectives.
- Can it take -er/-est or pair with more/most? Most true adjectives can be compared this way; verbs and nouns generally can't.
- Would an adverb test fail? If replacing it with an -ly word breaks the sentence's meaning around a noun, you're looking at an adjective, not an adverb.
Is ___ an Adjective? Quick Answers
Some words shift categories depending on how they're used, or only work in one position.
| Word | Answer |
|---|---|
| main | Adjective, but only before a noun ("the main reason"). It can't follow a linking verb. |
| asleep | Adjective, but only after a linking verb ("The man is asleep"). It can't sit before a noun. |
| fast | Can be either an adjective ("a fast car") or an adverb ("she runs fast"). |
| well | Usually an adverb ("sings well"), but an adjective when it means "in good health" ("I am well"). |
| rich | Usually an adjective ("rich people"), but functions as a noun when it describes a group as a whole ("the rich"). |
