Comparative adjectives are essential for comparing two nouns, but how are they formed correctly? COMPARE.EDU.VN offers a comprehensive guide, simplifying English grammar. This article explores simple rules, exceptions, and usage examples. Master comparative forms and enhance your descriptive writing!
1. What Are Comparative Adjectives?
Comparative adjectives are used to describe the differences between two nouns. This involves modifying adjectives to indicate a greater or lesser degree of a particular quality. Comparative adjectives are fundamental in enhancing descriptive capabilities and understanding language nuances.
1.1. Why Use Comparative Adjectives?
Using comparative adjectives helps to make clear comparisons and contrasts between two subjects. For instance, instead of saying “This car is fast, and that car is fast,” you can say “This car is faster than that car.” This not only saves words but also provides a clearer understanding of the relative speeds of the two cars.
1.2. Basic Structure
The basic structure for using comparative adjectives involves modifying the adjective and often using the word “than” to show the comparison:
- Adjective + -er + than: For most one-syllable adjectives.
- More + Adjective + than: For longer adjectives or those ending in -ful, -ous, -ing, etc.
Understanding these basic rules will help you construct grammatically correct and meaningful comparisons.
2. Rules for Forming Comparative Adjectives
Forming comparative adjectives correctly involves following a few key rules that depend on the number of syllables in the original adjective. These rules dictate whether you add “-er” to the end of the word or use “more” before it.
2.1. One-Syllable Adjectives
For most one-syllable adjectives, the comparative form is created by adding “-er” to the end of the word. This is a straightforward way to show that something has more of a particular quality than something else.
-
Examples:
- Old → Older (This house is older than that one.)
- Fast → Faster (A sports car is faster than a sedan.)
- Big → Bigger (An elephant is bigger than a cat.)
- Tall → Taller (He is taller than his brother.)
- Short → Shorter (The red dress is shorter than the blue one.)
- Strong → Stronger (This rope is stronger than the other.)
- Weak → Weaker (His eyesight is weaker than it used to be.)
- High → Higher (The mountain is higher than the hill.)
- Low → Lower (The temperature is lower today than yesterday.)
- Hard → Harder (This task is harder than I thought.)
- Soft → Softer (This pillow is softer than the other.)
- Dark → Darker (The night is darker than usual.)
- Light → Lighter (This box is lighter than that one.)
- Cheap → Cheaper (This shirt is cheaper than the one I saw yesterday.)
- Rich → Richer (She is richer than her parents.)
- Poor → Poorer (They are poorer this year due to the economic crisis.)
- Cold → Colder (Winter is colder than autumn.)
- Warm → Warmer (Spring is warmer than winter.)
- Long → Longer (This road is longer than the one we took last time.)
- Young → Younger (My sister is younger than me.)
- New → Newer (This car is newer than my old one.)
- Thick → Thicker (This book is thicker than the magazine.)

- Clear → Clearer (The sky is clearer today.)
- Close → Closer (The store is closer to my house than yours.)
- Wide → Wider (This river is wider than the stream.)
- Deep → Deeper (The ocean is deeper than the lake.)
- Bright → Brighter (The sun is brighter today than yesterday.)
2.2. One-Syllable Adjectives Ending in -e
When a one-syllable adjective already ends in “-e,” you only need to add “-r” to create the comparative form. This avoids having a double “-ee” at the end of the word.
-
Examples:
- Nice → Nicer (This restaurant is nicer than the one we went to last week.)
- Safe → Safer (This neighborhood is safer than downtown.)
- Wide → Wider (This road is wider than the other.)
- Large → Larger (An elephant is larger than a horse.)
- Late → Later (I woke up later than usual this morning.)
- Fine → Finer (The quality of this fabric is finer than that one.)
- Close → Closer (The grocery store is closer than the pharmacy.)
- Pale → Paler (She looks paler today than she did yesterday.)
- Rare → Rarer (This stamp is rarer than the other one in my collection.)
- Pure → Purer (The mountain air is purer than city air.)
- Sure → Surer (I am surer of my answer this time.)
- Base → Baser (His motives were baser than I had imagined.)
- Sane → Saner (After a good night’s sleep, I felt saner.)
- Dope → Doper (This song is doper than their last hit.)

- Tape → Taper (This tape is taper than the last.)
- True → Truer (This story is truer than the movies.)

- Bare → Barer (The tree is barer than before.)
- Brave → Braver (He is braver than his friends.)
- Dire → Direr (The situation is direr than we expected.)
2.3. One-Syllable Adjectives with a Vowel and Consonant
For one-syllable adjectives that end in a vowel followed by a consonant, the consonant is usually doubled before adding “-er.” This rule helps maintain the sound and pronunciation of the word.
-
Examples:
- Big → Bigger (An elephant is bigger than a cat.)
- Hot → Hotter (The desert is hotter than the forest.)
- Fat → Fatter (He got fatter after the holidays.)

- Dim → Dimmer (The room is dimmer now that the sun has set.)
- Grim → Grimmer (The situation is grimmer than we thought.)
- Slim → Slimmer (The chances are slimmer than before.)

- Wig → Wigger (This wigger is wigger than the last.)
- Zig → Zigger (The zigger is zigger than before.)
2.4. Two-Syllable Adjectives Ending in -y
When dealing with two-syllable adjectives that end in “-y,” the “-y” is changed to “-i” before adding “-er.” This rule ensures correct spelling and pronunciation.
-
Examples:
- Happy → Happier (She is happier now than she was before.)

- Sandy → Sandier (The beach is sandier on this side.)
- Smelly → Smillier (This dog is smillier than before.)
- Wary → Warier (He is warier than before.)
2.5. Two or More Syllable Adjectives
For most adjectives with two or more syllables, the comparative form is created by placing “more” before the adjective. This is a common method for adjectives that are longer and would sound awkward with an “-er” ending.
-
Examples:
- Beautiful → More beautiful (She is more beautiful than her sister.)

3. Exceptions to the Rules
While the rules for forming comparative adjectives are generally consistent, there are some notable exceptions. These exceptions often involve irregular forms or adjectives where both “-er” and “more” can be used, depending on context and style.
3.1. Irregular Adjectives
Some adjectives have irregular comparative forms that do not follow the standard rules. These forms must be memorized, as they do not logically derive from the base adjective.
-
Examples:
- Good → Better (This apple pie is better than the last one.)
- Bad → Worse (The weather today is worse than yesterday.)
- Far → Farther/Further (My house is farther from the school than yours.)
3.2. Adjectives with Flexible Forms
Certain two-syllable adjectives can take either “-er” or “more” to form the comparative, often depending on personal preference or regional usage.
-
Examples:
- Clever → Cleverer / More clever (He is cleverer than I thought. / He is more clever than I thought.)
- Simple → Simpler / More simple (This solution is simpler than the other. / This solution is more simple than the other.)
- Quiet → Quieter / More quiet (The library is quieter than the cafe. / The library is more quiet than the cafe.)
3.3. Compound Adjectives
Compound adjectives, especially those that are hyphenated, typically use “more” to form the comparative.
-
Examples:
- Well-known → More well-known (This author is more well-known than the other.)
- User-friendly → More user-friendly (This software is more user-friendly than the previous version.)
4. Using “Than” in Comparisons
The word “than” is crucial when using comparative adjectives because it explicitly states what two items or subjects are being compared. It provides the necessary context to understand the relationship between the two.
4.1. Structure with “Than”
The standard structure for using “than” in comparisons is:
- Subject + Verb + Comparative Adjective + Than + Object of Comparison
4.2. Examples in Sentences
-
Simple Comparisons:
- “My car is faster than yours.”
- “She is taller than her brother.”
- “This book is more interesting than the last one I read.”
-
Complex Comparisons:
- “The cost of living in New York is higher than in Chicago.”
- “Learning a new language is more challenging than learning a new software program.”
4.3. Common Mistakes to Avoid
- Using “Then” Instead of “Than”: “Than” is used for comparisons, while “then” is used to indicate time or sequence.
- Omitting “Than”: Forgetting to include “than” can make the comparison unclear or grammatically incorrect.
- Incorrect Word Order: Ensure that the sentence structure follows the correct order to avoid confusion.
5. Examples of Comparative Adjectives in Sentences
To further illustrate how comparative adjectives are used, here are several examples across different contexts:
5.1. Describing People

5.5. Comparative Adjectives in Marketing
- “Our product is cheaper and more effective than the competition.”
- “Experience a smoother, faster, and more reliable service with us.”
- “Get results that are more impactful than ever before.”
6. Comparative vs. Superlative Adjectives
It’s important to distinguish between comparative and superlative adjectives. Comparative adjectives compare two things, while superlative adjectives compare three or more things, indicating the highest degree of a quality.
6.1. Comparative Adjectives
- Used to compare two items.
- Often uses “than” in the sentence.
- Examples: “taller,” “more interesting.”
6.2. Superlative Adjectives
- Used to compare three or more items.
- Often uses “the” before the adjective.
- Formed with “-est” for short adjectives or “most” for longer adjectives.
- Examples: “tallest,” “most interesting.”
6.3. Examples Illustrating the Difference
-
Comparative: “John is taller than Peter.”
-
Superlative: “John is the tallest in the class.”
-
Comparative: “This book is more interesting than that one.”
-
Superlative: “This book is the most interesting one I have ever read.”
7. Common Mistakes with Comparative Adjectives
Even with a solid understanding of the rules, it’s easy to make mistakes when using comparative adjectives. Here are some common errors and how to avoid them:
7.1. Double Comparatives
Avoid using both “more” and “-er” with the same adjective. This is a common error that sounds awkward.
- Incorrect: “This car is more faster than that one.”
- Correct: “This car is faster than that one.”
7.2. Misusing “Than” and “Then”
“Than” is used for comparisons, while “then” is used for time or sequence. Mixing these up is a common mistake.
- Incorrect: “She is taller then her brother.”
- Correct: “She is taller than her brother.”
7.3. Incorrect Irregular Forms
Make sure to use the correct irregular comparative forms for adjectives like “good,” “bad,” and “far.”
- Incorrect: “This is gooder than that.”
- Correct: “This is better than that.”
7.4. Not Doubling Consonants
Remember to double the final consonant in one-syllable adjectives that end in a vowel followed by a consonant before adding “-er.”
- Incorrect: “This box is biger than the other.”
- Correct: “This box is bigger than the other.”
7.5. Using the Base Form of Adjective
Ensure that you do not use the base form of adjective while making a comparison.
- Incorrect: “She is tall than her brother.”
- Correct: “She is taller than her brother.”

- “The food was less spicy than I expected.”
8.3. Comparisons with “As…As”
Use “as…as” to show that two things are equal in a particular quality.
- “She is as tall as her brother.”
- “This book is as interesting as the one I read last week.”
- “The weather today is as cold as yesterday.”
8.4. Using Comparative Adjectives to Show Preference

13. FAQs About How to Make Comparative Adjectives
13.1. What is a comparative adjective?
A comparative adjective is used to compare two nouns, indicating which one has more or less of a particular quality. It is formed by adding “-er” to short adjectives or using “more” before longer adjectives.
13.2. How do you form comparative adjectives for one-syllable words?
For most one-syllable adjectives, you add “-er” to the end of the word. For example, “old” becomes “older,” and “fast” becomes “faster.” If the adjective ends in “-e,” just add “-r,” like “nice” becoming “nicer.” If the adjective ends in a vowel followed by a consonant, double the consonant before adding “-er,” such as “big” becoming “bigger.”
13.3. What do you do with two-syllable adjectives ending in -y?
Change the “-y” to “-i” and add “-er.” For example, “happy” becomes “happier,” and “easy” becomes “easier.”
13.4. How do you form comparative adjectives for adjectives with two or more syllables?
Generally, you use “more” before the adjective. For example, “beautiful” becomes “more beautiful,” and “expensive” becomes “more expensive.”
