Adjectives play a vital role in all forms of communication, ranging from casual descriptions to technical writing. Nevertheless, the effective use of adjectives is not about using any form of description but entails knowing appropriate classification, order, and correct comparative structures.
This article explains everything in clear terms. Whether you are a student, a language learner, or a writer, by the end of it you will know exactly what an adjective is, recognize one when you see one, and use every single adjective correctly.
What Is an Adjective?
An adjective is a word that describes or modifies a noun or a pronoun. It provides details about the type, number, possession, or identification of a noun or pronoun. Examples of questions answered by an adjective include:
| What type? | The wild cat |
| How many? | Six curtains |
| Whose? | Our room |
| Which one? | That building |
Language without adjectives would be rather boring. In comparison, for example, compare “the car is fast” with just “the car”. An adjective can be defined simply as an attributive that gives more meaning to a noun.
An adjective can appear directly before the noun it describes (“a brilliant idea”), or follow the noun through a linking verb such as “is,” “seems,” or “appears” (“the idea appears brilliant”). Both uses are grammatically correct; they are just placed in different contexts in the sentence.
How to Identify an Adjective in a Sentence
Identifying the adjectives within a sentence becomes much easier when one knows what to look for. The process can be reduced to a simple three-step test:
- Identify the noun or pronoun. All adjectives are linked with something like a person, place, idea, or thing.
- What is it describing about the noun? Does the word indicate whether the noun possesses a particular quality, quantity, or belongs to someone?
- Try removing the word. See if the sentence would still be grammatically correct, though missing something important. For example, take the sentence “He wore a yellow suit.” Leaving out the adjective makes it “He wore a suit.”
Here’s a handy trick often taught by English teachers. Adjectives normally give answers to one of the following questions: What kind? How many? Which one?
Types of Adjectives, With Examples
There are several different types of adjectives which have distinct functions in sentences. Learning how many different types of adjectives and their functions will help you learn how to use them correctly and properly, especially when you use more than one adjective in one sentence.
Here’s a short list of different types of adjectives and their definitions, which will be examined more closely below:
| Types | Explanation | Example |
| Descriptive | Describes quality | Yellow, big, happy |
| Quantitative | Describes quantity | Some, many, four |
| Possessive | Indicates possession | My, your, their |
| Demonstrative | Refers to specific nouns | That, those, this, these |
| Interrogative | Asks questions | Which, whose, what |
| Comparative and superlative | Compare nouns | Shorter, shortest |
Now, let’s examine each of these categories separately, starting from the three most frequently used ones.
Descriptive, Quantitative, and Demonstrative Adjectives
Descriptive adjectives: These are what most people have in mind when they think of adjectives. They describe the nature or characteristic of a noun through the use of words like size, colour, character traits, or condition of the subject. Some basic examples are cheerful, rusty, quiet, and enormous.
For example: The old bookshelf is placed in the silent hallway of the palace.
Quantitative adjectives: As the name implies, this type of adjective quantifies the nouns that they modify. The words included in this group are some, few, several, enough, and actual figures like three. They are used to answer the questions “how many” or “how much”.
For example: “I have a few apples left” or “I saw dozens of bananas in the kitchen.”
Demonstrative adjectives: These adjectives point out the particular noun that is referred to in the sentence. Only four words belong to this category, which are this, that, these, and those. The key to using demonstrative adjectives correctly is distance and number; like this and these refer to something close (singular and plural), whereas that and those refer to something farther away.
For example: “This dress belongs to her, but those shirts are mine.”
Possessive and Interrogative Adjectives
Possessive adjectives: They denote possession or an association between a noun and its possessor. The common ones are my, your, his, her, its, our, and their. However, unlike possessive pronouns (mine, yours, hers), possessive adjectives are always placed in front of a noun.
For example:
Her umbrella is by the door. (Possessive adjective)
The umbrella is hers. (Possessive pronoun)
Interrogative adjectives: We use these adjectives to ask questions about nouns. Common examples include “which,” “what,” and “whose.” They function as adjectives when they come before a noun rather than standing alone as pronouns.
For example:
Which umbrella is yours? (interrogative adjective since it modifies the noun umbrella)
Which is yours? (it is an interrogative pronoun, standing alone)
One interesting thing is that some of the determiners have similarities with pronouns according to their usage in the sentence; what matters is that the determiner must modify a noun that follows immediately after it.
The Correct Order of Adjectives in a Sentence
Many may find correctly placing the adjectives in a sentence the most challenging aspect. When there are multiple adjectives used before a noun, then the adjectives must be arranged in a certain way. If the order of the adjectives is incorrect, the sentence will sound “awkward,” despite using proper words.
The standard order is mentioned below:
- Opinion (interesting)
- Size (tall)
- Age (ancient)
- Shape (square)
- Colour (brown)
- Origin (French)
- Material (metal)
- Purpose (table)
Combined, you will get a sentence like: “An interesting tall ancient square brown French metal table.’ It may seem like a pile of adjectives, but the order sounds right because it adheres to the natural way our ears perceive such an arrangement.
Quick tip: To remember the order, you can follow the acronym OSASCOMP (Opinion, Size, Age, Shape, Color, Origin, Material, Purpose). Not all categories are always needed; often, just two or three adjectives suffice. But when stacking adjectives, this order will keep the sentence sounding natural and not clumsy.
Comparative and Superlative Adjectives
Besides describing objects, adjectives can also make comparisons of these objects by telling that one object possesses a certain property more (or less) than another. In other words, comparative and superlative adjectives make comparisons between nouns.
Comparative adjectives are used to compare two nouns and end with -er, or have more or less before the adjective.
For example:
Big → Bigger
Happy → Happier
Beautiful → More beautiful
Superlative adjectives compare three or more objects and show the highest or lowest degree. We usually form them by adding -est to an adjective or by placing “most” or “least” before it:
For example:
Short → Shortest
Big → Biggest
Beautiful → Most Beautiful
As a rule, one-syllable adjectives take -er/-est endings. Adjectives ending in “y” take -ier/-iest, while multi-syllable adjectives use “more/most” or “less/least” instead of -er/-est endings.
Next, consider irregular comparisons. These forms do not follow standard rules, so you need to memorize them.
| Base Adjective | Comparative | Superlative |
| far | further/farther | furthest/farthest |
| bad | worse | worst |
| good | better | best |
| little | less | least |
| many/much | more | most |
This is the list of irregular forms of comparatives and superlatives that many learners struggle with; therefore, memorizing them might be more beneficial for you than trying to figure out a nonexistent rule.
Adjectives vs. Adverbs: What’s the Difference?
Confusion between adjectives and adverbs is one of the most prevalent mistakes that happen among English language learners and writers. The difference is easy to spot with one test. Remember, adjectives modify nouns and pronouns, whereas adverbs modify verbs, adjectives, and other adverbs.
For example:
I feel bad.
I feel badly.
In this case, feel is a linking verb describing some state of being, thus requiring an adjective – the same way you would say “I feel happy” or “I feel tired”. “I feel badly” means something is wrong with your sense of touch.
Simple trick to differentiate between both: Adverbs normally (but not always) take the form of
-ly, such as quickly, quietly, and carefully. They can answer how, where, or when something is being done. On the other hand, adjectives modify nouns and are used to answer questions such as what kind or which noun is being referred to. In case of describing actions, use adverbs (“she ran quickly”). For describing people or things, use adjectives (“she is quick”).
Quick reference: a List of Common Adjectives by Type
Here’s a table of quick references to look up whenever you want adjective examples from a specific category.
| Type | Examples |
| Descriptive | Happy, sad, big, rusty, amazing etc. |
| Quantitative | Some, few, many, several, actual numbers |
| Demonstrative | This, that, these, those |
| Possessive | My, your, our, their |
| Interrogative | Which, what, whose |
| Comparative | Taller, better, more interesting |
| Superlative | Shortest, best, most interesting |

What is the difference between an adjective and an adverb?
The adjective modifies a noun or pronoun, while the adverb modifies a verb or another adjective. The word “quick” is an adjective, while “quickly” is an adverb.
Can a noun function as an adjective?
Yes, a noun can act as an adjective when it directly modifies another noun. For example, “coffee cup” or “kitchen table”. Here, ‘kitchen’ and ‘coffee’ are nouns, but they describe ‘table’ and ‘cup’ working the same way an adjective would.
