As you know, an adjective in English describes a noun. An adverb describes a verb, an adjective, another adverb, or even an entire sentence.
Most adverbs have a special ending: -ly. You can form adverbs from some adjectives, but you must be careful of the spelling.
Here are some rules to help you.
1. Adding -ly to the end of the adjective

Many adjectives can be transformed into adverbs. In most cases, we do this by simply adding -ly to the end of the adjective.
Here are some examples:
- suddenly
- brightly
- slowly
- mysteriously
- really
- interestingly
- politely
- kindly
- generously
- calmly
- nervously
- generally
2. Adjectives ending in -y
Fred looked hungrily at his big ice cream cone.
When the adjective you want to make into an adverb ends in -y, you must change the y to an i, then add -ly.
Here are some common examples:
- happily
- angrily
- clumsily
- lazily
- hastily
- messily
- readily
- stealthily
- cozily
3. Adjectives that end in -le
Marlene is sitting comfortably in her favorite chair.
When the adjective ends in -le, remove the e and replace it with a y.
For example:
- terribly
- incredibly
- adorably
- acceptably
- understandably
- noticeably
- recognizably
- predictably
- suitably
- remarkably
4. Comparative and superlative adverbs
Dave's car is moving more slowly than Ethan's car.
Finally, when you want to form a comparative or a superlative adverb, you should add "more" before the adverb to make it comparative, and "most" to make it superlative.
For example:
Correct: Paul spoke more politely than Erica.
Incorrect: Paul spoke politelier than Erica.
Correct: I saw the most amazingly beautiful film yesterday!
Incorrect: I saw the amazingliest beautiful film yesterday!
Remember that the adverb well is irregular. Its comparative form is better, and its superlative form is best.
Correct: Mark did better on the test than I did, but Amanda did the best.
Incorrect: Mark did more well on the test than I did, but Amanda did the most well.
Review
So, let's review what we have learned about forming adverbs in English:- Most adjectives that can be transformed into adverbs simply
need -ly
added to the end.
- If the adjective ends in -y, you must change
the y to i, then add -ly.
- If the adjective ends in -le, you should
remove the e
and add -y.
- To form a comparative adverb, add "more" before it. To make
it superlative, add "most." Remember that the adverb "well" is
irregular.
