Adjectives, Adverbs, and Comparisons

Introduction

Words help you build clear pictures and precise ideas. Adjectives describe nouns and pronouns, while adverbs add information about actions, descriptions, and other adverbs. When you compare people, animals, objects, places, or actions, you can use comparative and superlative forms.

In this aiMOOC, you will learn how to identify adjectives and adverbs, choose useful describing words, form comparisons, notice common spelling patterns, and use comparison words correctly in your own speaking and writing.

The image above shows that English grammar contains different word classes. In this course, you will focus especially on adjectives and adverbs and how they work with nouns and verbs.

Adjectives

An adjective gives more information about a noun or pronoun. It can tell you what something is like.

Examples: a noisy classroom, a blue backpack, three tiny insects, the soup is hot.

In a noisy classroom, the adjective noisy describes the noun classroom. In the soup is hot, the adjective hot comes after the linking verb is and describes soup.

Adjectives can describe size, color, shape, age, feeling, quality, and many other features. Useful questions include: What kind? Which one? What is it like?

The picture can be described with opposite adjectives such as happy and sad. Try adding your own adjectives, for example yellow, round, or funny.

Adjectives in Sentences

Adjectives often come before nouns: a fast train, an interesting book, a cold morning. They can also come after linking verbs such as be, seem, look, feel, sound, smell, and taste: The train is fast. The book seems interesting.

A sentence may use more than one adjective. For example, We saw a small red kite. At this level, focus first on choosing adjectives that make your meaning clear.

Adverbs

An adverb often gives more information about a verb. It can tell you how, when, where, or how often something happens.

Examples: The turtle moved slowly. We arrived yesterday. Come here. I often read after school.

Many adverbs of manner are formed by adding -ly to an adjective: quick → quickly, careful → carefully, quiet → quietly. But not every adverb ends in -ly, and not every word ending in -ly is an adverb. For example, fast can be an adjective or an adverb, and friendly is usually an adjective.

Adverbs Can Modify More Than Verbs

An adverb can also strengthen or change an adjective: very tall, really funny, extremely cold. It can modify another adverb: very quickly, quite carefully.

To decide whether a word is an adjective or an adverb, ask what it is describing. Compare these sentences:

Maya is a careful writer. Here, careful describes the noun writer, so it is an adjective.

Maya writes carefully. Here, carefully describes how Maya writes, so it is an adverb.

Adverbs of Frequency

Adverbs such as always, usually, often, sometimes, rarely, and never tell how often something happens. They usually come before the main verb: I often walk to school. With the verb be, they usually come after it: I am often early.

Comparing with Adjectives

You use a comparative adjective to compare two people or things. You use a superlative adjective to show the highest or lowest degree in a group.

Base form: tall

Comparative: taller — The sunflower is taller than the daisy.

Superlative: tallest — The sunflower is the tallest plant in the row.

Forming Comparatives and Superlatives

For many short adjectives, add -er for the comparative and -est for the superlative: small, smaller, smallest; long, longer, longest.

If a short adjective ends in e, add -r or -st: nice, nicer, nicest.

For some short adjectives ending in one vowel followed by one consonant, double the final consonant: big, bigger, biggest; hot, hotter, hottest.

If an adjective ends in a consonant plus y, change y to i before adding the ending: happy, happier, happiest.

For many longer adjectives, use more and most: careful, more careful, most careful; interesting, more interesting, most interesting.

Do not normally combine both patterns. Say more interesting, not more interestinger.

The red line is longer than the blue line, and the blue line is shorter than the red line. This is a simple example of a comparison between two things.

Irregular Comparison

Some very common adjectives have irregular forms that you need to learn.

good → better → best

bad → worse → worst

far → farther or further → farthest or furthest

Use the form that fits your meaning: This puzzle is better than the last one. That was the best answer in the group.

Comparing with Adverbs

Adverbs can be compared too. Short adverbs often use -er and -est: fast, faster, fastest and hard, harder, hardest. Many adverbs ending in -ly use more and most: carefully, more carefully, most carefully.

Some are irregular: well, better, best and badly, worse, worst.

Compare:

Nora runs faster than Sam.

Of the three runners, Nora runs the fastest.

Lee solved the puzzle more carefully than I did.

Ava explained the idea most clearly.

Equal and Unequal Comparisons

Sometimes two things are equal in one quality. Use as ... as: The blue rope is as long as the green rope. You can use this pattern with adverbs too: Kim reads as quickly as Jo.

To show that two things are not equal, use not as ... as: This box is not as heavy as that box.

You can also use less and least: This route is less crowded than the other route. Monday was the least busy day.

Choosing the Right Form

First, decide what you are describing. If you are describing a noun or pronoun, you usually need an adjective. If you are describing an action, you often need an adverb.

Next, decide whether you are simply describing, comparing two, or selecting one from a group. Use the base form for a description, the comparative for a comparison between two, and the superlative for the highest or lowest degree in a group.

Watch for meaning, not only endings. In The cheetah is fast, fast is an adjective. In The cheetah runs fast, fast is an adverb.

Common Mistakes

A common mistake is using an adjective when an adverb is needed: She sings beautiful should usually be She sings beautifully.

Another mistake is making a double comparison: use better, not more better; use most interesting, not most interestingest.

Remember to use than after many comparatives: A bike is faster than walking. Superlative adjectives commonly use the: This is the tallest tree in the park.

Evidence of Learning

Strong evidence of learning includes your ability to identify adjectives and adverbs in context, explain what each word modifies, and choose forms that fit the meaning of a sentence.

You should be able to form regular and common irregular comparatives and superlatives, use than and as ... as correctly, and compare both qualities and actions.

Useful products include edited paragraphs, comparison posters, survey results, spoken explanations, short videos, and data-based comparison sentences. The strongest evidence shows that you can transfer the grammar to new topics instead of only completing isolated exercises.
