Adjectives updated on  January 10, 2024 4 min read
A comparative adjective indicates a higher or lower degree of a specific attribute (e.g., “faster,” “less trusted”) in a comparison of two people, things, or groups.

Most comparative adjectives are created either by adding the suffix “-er” (e.g., “younger”) or by adding “more” (e.g., “more famous”) or “less” (e.g., “less popular”) before the adjective. The form each comparative adjective takes is determined in part by the number of syllables in the original adjective.

Comparative adjectives examples
The coffee is hotter at the café across the street.
The blue dress is prettier than the green one.
This phone is more expensive than the previous model.

What is a comparative adjective?

A comparative adjective characterizes a noun or pronoun as possessing a specific attribute to a greater or lesser extent compared to another person, thing, or group.

All comparative adjectives involve comparisons, whether implied (e.g., “Yesterday’s coffee was better”) or stated explicitly (e.g., “Robert is shorter than Jim”).

Comparative adjective examples in sentences
Jane Goodall is considered a more influential primatologist than many of her contemporaries.
Hawaii’s climate is warmer than Alaska’s.
The shorter of the two mountain peaks is less challenging to climb.

How are comparative adjectives formed?

Most comparative adjectives are constructed following straightforward patterns based on syllable count. There are also irregular adjectives that defy any specific pattern, which may require memorization.

In most cases, one- and two-syllable adjectives can be changed to the comparative form by appending the suffix “-er.” For adjectives with three or more syllables (and some two-syllable adjectives), insert “more” before the base adjective.

Syllable count

Comparative form

Examples

One-syllable

Add “-er”

mean; meaner
slow; slower
strong; stronger

Two syllables

Add “-er” or add “more” or “less” before the adjective

narrow; narrower
patient; more patient
quiet; quieter

Three or more syllables

Add “more” or “less” before the adjective

adventurous; more adventurous
curious; more curious
mysterious; more mysterious

If an adjective has an “-e” ending, the comparative can be formed by adding “-r.” For most adjectives ending in “-y,” change the “-y” to “i” and add “-er.” For adjectives that end in a consonant-vowel-consonant pattern, double the final consonant and add “-er” to form the comparative.

Original ending

Comparative ending

Examples

“-e”

Add “-r”

brave; braver
large; larger
wide; wider

“-y”

Change “-y” to “i” and add “-er”

lovely; lovelier
spicy; spicier
noisy; noisier

Consonant + vowel + consonant

Double the final consonant and add “-er”

hot; hotter
red; redder
fit; fitter

Note
For a few one-syllable adjectives ending in “-y,” there are two acceptable spellings of the comparative form. These words include “sly” (“slyer” or “slier”) and “spry” (“spryer” or “sprier”). Consult your preferred dictionary or style guide to determine whether one spelling is preferred in your discipline.

Irregular comparative adjectives

Irregular comparative adjectives deviate from the standard patterns of forming comparatives, which involve adding the “-er” suffix or using “more” or “less” before the base form of the adjective.

How are comparative adjectives used in sentences?

Sentences that include comparative adjectives often follow a specific structure: noun/pronoun (subject) + verb + “more”/“less” + adjective + “than” + noun/pronoun (e.g., “Terence is more excited than John”).

In sentences that don’t use “more” or “less,” a comparative adjective ending in “-er” is used instead of the base form (e.g., “Your car is nicer than mine”).

A sentence may also take a much simpler form, such as the following pattern: noun/pronoun (subject) + linking verb + comparative adjective (e.g., “He is friendlier”). In these instances, the comparison is implied rather than explicit.

Examples: Comparative adjectives
Blake seems less judgmental than Mary.
I’m taller than my dad.
Studying this weekend is more important than going fishing.

Note
Sentences that contain comparative adjectives can take various forms. For example, the sentence “John is always happier in summer” contains a prepositional phrase (“in summer”) rather than a noun or pronoun that is modified by the comparative adjective.

Comparative and superlative adjectives

The comparative and superlative degrees differ in scope, though both are used to make comparisons. Comparative adjectives are typically used to compare two people, things, or groups. Superlative adjectives compare one person, thing, or group to multiple others.

Examples: Comparative vs superlative degree examples
His grades are better than they were last semester.
His grades are the best they’ve ever been.

I’ve never been prouder.
I’m the proudest I’ve ever been.

You’re more honest than your sister.
You’re the most honest person I’ve ever met.
