Definition of Adjectives for Comparison
Adjectives for comparison are used to describe the degree of a quality or characteristic of nouns. These adjectives enable us to compare two or more things, indicating whether one has more or less of a particular attribute than another.
This comparison is essential for providing detailed descriptions and making clear distinctions between subjects.
In English grammar, there are three primary forms used for comparison: the positive, the comparative, and the superlative. The positive form is the base adjective, used to describe a single noun without comparison (e.g., tall). The comparative form compares two nouns (e.g., taller). The superlative form compares three or more nouns, indicating the highest degree of the quality (e.g., tallest).
Understanding these forms is critical for constructing grammatically correct and meaningful sentences. Adjectives of comparison are used widely in everyday conversations, academic writing, and professional communications.
They help in expressing opinions, making evaluations, and providing precise descriptions.
Structural Breakdown
The structural formation of comparative and superlative adjectives depends largely on the number of syllables in the base adjective. Generally, shorter adjectives (one or two syllables) form their comparative and superlative forms by adding suffixes.
Longer adjectives (three or more syllables) typically use the words “more” and “most” before the adjective.
For one-syllable adjectives, the comparative form is usually created by adding “-er” to the end of the adjective, and the superlative form is created by adding “-est”. For example, tall becomes taller and tallest. However, there are exceptions, especially when the adjective ends in a consonant-vowel-consonant sequence; in these cases, the final consonant is often doubled (e.g., big becomes bigger and biggest).
Two-syllable adjectives can sometimes follow the same rule as one-syllable adjectives (adding “-er” and “-est”), especially if they end in “-y,” “-er,” “-le,” or “-ow.” For example, happy becomes happier and happiest. However, many two-syllable adjectives and all adjectives with three or more syllables use “more” and “most” to form the comparative and superlative, respectively. For example, beautiful becomes more beautiful and most beautiful.
Irregular adjectives, such as good, bad, and far, have unique comparative and superlative forms that do not follow the standard rules. These must be memorized. For example, good becomes better and best; bad becomes worse and worst; and far becomes farther/further and farthest/furthest.
Types and Categories
Adjectives for comparison can be categorized into four main types: comparative adjectives, superlative adjectives, adjectives of equality, and adjectives of inequality. Each type serves a specific purpose in comparing nouns and expressing different degrees of qualities.
Comparative Adjectives
Comparative adjectives are used to compare two nouns. They indicate which noun has more or less of a particular quality.
The comparative form is typically followed by the word “than” to specify what is being compared.
Examples:
- “My car is faster than yours.”
- “She is more intelligent than her brother.”
- “This book is more interesting than the last one I read.”
Superlative Adjectives
Superlative adjectives are used to compare three or more nouns, indicating which noun has the highest degree of a particular quality. The superlative form is often preceded by the word “the.”
Examples:
- “He is the tallest student in the class.”
- “This is the most beautiful painting in the museum.”
- “She is the smartest person I know.”
Adjectives of Equality
Adjectives of equality are used to indicate that two nouns have the same degree of a particular quality. They typically use the structure “as + adjective + as.”
Examples:
- “He is as tall as his father.”
- “This movie is as interesting as the book.”
- “She is as smart as her sister.”
Adjectives of Inequality
Adjectives of inequality are used to indicate that two nouns do not have the same degree of a particular quality. They often use the structure “not as + adjective + as” or “less + adjective + than.”
Examples:
- “He is not as tall as his father.”
- “This movie is not as interesting as the book.”
- “She is less smart than her sister.”

Usage Rules
Using adjectives for comparison correctly requires understanding several rules. These rules govern the formation of comparatives and superlatives, as well as their proper usage in sentences.
Rule 1: For most one-syllable adjectives, add “-er” for the comparative form and “-est” for the superlative form. If the adjective ends in a consonant-vowel-consonant sequence, double the final consonant (e.g., big, bigger, biggest).
Rule 2: For two-syllable adjectives ending in “-y,” “-er,” “-le,” or “-ow,” usually change the “-y” to “-i” and add “-er” and “-est.” Otherwise, use “more” and “most” (e.g., happy, happier, happiest; simple, simpler, simplest; narrow, narrower, narrowest).
Rule 3: For adjectives with three or more syllables, use “more” for the comparative form and “most” for the superlative form (e.g., beautiful, more beautiful, most beautiful).
Rule 4: Some adjectives are irregular and have unique comparative and superlative forms. These include good (better, best), bad (worse, worst), and far (farther/further, farthest/furthest).
Rule 5: When comparing two things, always use the comparative form followed by “than.” When comparing three or more things, use the superlative form, often preceded by “the.”
Rule 6: Use “as + adjective + as” to show equality and “not as + adjective + as” or “less + adjective + than” to show inequality.
Rule 7: Avoid using double comparatives or superlatives (e.g., “more better,” “most best”). This is grammatically incorrect. Use either “better” or “best,” but not both with “more” or “most.”

Advanced Topics
For advanced learners, there are several more complex aspects of adjectives for comparison to explore, including double comparatives and incomplete comparisons.
Double Comparatives
Double comparatives involve using “the” before both the comparative clause and the main clause to show a proportional increase or decrease. This construction indicates that as one thing changes, another thing changes in a related way.
Examples:
- “The more you study, the better you will understand.”
- “The faster you drive, the more dangerous it becomes.”
- “The less you worry, the happier you will be.”
Incomplete Comparisons
Incomplete comparisons occur when the second term of comparison is implied or omitted. This is often used in informal language or when the context makes the comparison clear.
Examples:
- “This car is faster.” (than what is implied)
- “She is happier now.” (than she was before is implied)
- “He is the tallest.” (in his family or group is implied)
FAQ
Here are some frequently asked questions about adjectives for comparison:
Q1: What is the difference between comparative and superlative adjectives?
A: Comparative adjectives compare two things, while superlative adjectives compare three or more things. Comparative adjectives use “-er” or “more,” and superlative adjectives use “-est” or “most.”
Q2: When should I use “more” and “most” instead of “-er” and “-est”?
A: Use “more” and “most” with adjectives that have three or more syllables. For most one-syllable and some two-syllable adjectives, use “-er” and “-est.”
Q3: Are there any irregular comparative and superlative forms?
A: Yes, some common irregular adjectives include good (better, best), bad (worse, worst), and far (farther/further, farthest/furthest).
Q4: How do I use adjectives of equality and inequality?
A: Use “as + adjective + as” to show equality and “not as + adjective + as” or “less + adjective + than” to show inequality.
Q5: What are double comparatives and how are they used?
A: Double comparatives use “the” before both the comparative clause and the main clause to show a proportional increase or decrease, indicating that as one thing changes, another changes in a related way (e.g., “The more you study, the better you will understand”).
Q6: Can you give an example of incomplete comparisons?
A: An incomplete comparison is when the second term of comparison is implied or omitted. For example, saying “This car is faster” implies “than another car” or “than it used to be.”
Q7: Is it correct to say “more better” or “most best”?
A: No, it is grammatically incorrect to use double comparatives or superlatives. Use either “better” or “best” alone.
Q8: What should I do if I’m unsure whether to use “-er/-est” or “more/most”?
A: If you’re unsure, check a dictionary or grammar guide. Generally, if the adjective has three or more syllables, use “more/most.” If it’s a one-syllable adjective, use “-er/-est.” For two-syllable adjectives, it depends on the ending and usage.
