The Comparative and The Superlative

Comparative adjectives compare two nouns.

His truck is newer and bigger than mine.

Superlative adjectives describe nouns in an extreme way, as in being the most or the least of a quality.

But our sister, Samantha, had the newest and biggest truck of them all.

What Is a Comparative and Superlative Adjective?

Comparatives and superlatives are adjective forms used to describe nouns (a person, place, thing, or idea). But what’s the difference between comparative and superlative adjectives?

This quick guide will provide the answer by going over comparative forms of adjectives, superlative forms of adjectives, teaching you how to form them, discussing irregular comparatives and superlatives, and providing example sentences.

Comparative Form of Adjectives

Comparatives in English are used when comparing two nouns. There are two ways to create comparative adjectives.

You can either add “—er”:

Loud → Louder

Or, you can add more in front of the adjective.

Expensive → More expensive

The rule of thumb is that with short words (also known as monosyllabic), the comparative is formed by adding “—er” (e.g., lower), while longer words use a preceding more (e.g., more important). However, English language rules carry a boatload of exceptions, and this one is no different.

Here are a few more comparative examples:

Clean → Cleaner:

The house was cleaner than I remembered.

Round → Rounder:

Liam was teaching me how to mold a rounder sphere.

Peaceful → More peaceful:

Things have been more peaceful for me.

“Harder,” “better,” “faster,” and “stronger” are all comparatives.

Superlative Forms of Adjectives

The difference between comparative and superlative adjectives is that superlatives are used to show that an adjective is the most or least of a quality. In other words, they describe a noun in an extreme way. Usually, superlatives compare an individual to a group.

Like comparatives, there are two ways to form superlatives:

You can either add “—est”:

Loud → louder → loudest

Or by adding most in front of the adjective:

Expensive → more expensive → most expensive

Additionally, superlatives are always preceded by the determiner “the.”

Some superlative examples include:

Fat → fatter → fattest:

I chose the fattest puppy of them all.

High → higher → highest:

Jordan got the highest grade in the class.

Famous → More famous → Most famous:

She was the most famous sibling.

Like comparatives, forming superlatives means short words typically get “—est” while longer words get most in front of it.
