100 Adjectives and Their Adverbs in English with Exercises

Adjectives and adverbs are important parts of English grammar. They help us describe people, things, actions, and situations.

In this article, you will learn how to convert adjectives into adverbs with 100 examples. You will also practise using adverbs through fill-in-the-blanks exercises.

This article is useful for school students and anyone who wants to improve their English grammar.

1. What Is an Adjective?

An adjective is a word that describes a noun or a pronoun. It tells us more about a person, place, animal, or thing.

Examples:

1. He is a careful driver.
2. She is a beautiful girl.
3. It is a slow train.
4. Rahul is a brave boy.
5. This is a happy child.

The words careful, beautiful, slow, brave, and happy are adjectives.

2. What Is an Adverb?

An adverb is a word that modifies a verb, an adjective, or another adverb. It often tells us how, when, where, or how often something happens.

Examples:

1. He drives carefully.
2. She sings beautifully.
3. The train moves slowly.
4. Rahul fought bravely.
5. The child smiled happily.

The words carefully, beautifully, slowly, bravely, and happily are adverbs.

3. Rules for Converting Adjectives into Adverbs

Rule 1: Add -ly to the adjective

In many cases, we can form an adverb by adding -ly to an adjective.

Adjective	Adverb
Careful	Carefully
Beautiful	Beautifully
Slow	Slowly
Quick	Quickly
Honest	Honestly

Rule 2: Change -y to -ily

When an adjective ends in a consonant followed by y, we usually change y to i and add -ly.

Adjective	Adverb
Happy	Happily
Easy	Easily
Angry	Angrily
Heavy	Heavily
Lucky	Luckily

Rule 3: Add -ly to adjectives ending in -ful

Adjective	Adverb
Careful	Carefully
Hopeful	Hopefully
Beautiful	Beautifully
Useful	Usefully
Successful	Successfully

Rule 4: Some adjectives ending in -le change to -ly

When an adjective ends in -le, we often replace the final e with y.

Adjective	Adverb
Gentle	Gently
Simple	Simply
Humble	Humbly
Possible	Possibly
Comfortable	Comfortably

Rule 5: Some adverbs have irregular forms

Not all adverbs are formed by adding -ly.

Adjective	Adverb
Good	Well
Fast	Fast
Hard	Hard
Early	Early
Late	Late

Remember that hardly does not mean the same as hard. Hard means with great effort, while hardly usually means almost not.

For example:

• She works hard.
• She hardly works.

The meanings of these two sentences are different.
