Define Superlative Adverbs

“Of all the girls at the ball, Priscilla was dressed most beautifully.”

In the above sentence, most beautifully is an adverb form that describes the verb dressed. I could have simply stated that Priscilla was beautifully dressed or that she was dressed more beautifully than Erica. But since I wanted readers to know that her manner of dress far exceeded any other, I used a special type of adverb called a <strong>superlative adverb</strong>.

Let’s Define Superlative Adverb

A superlative adverb is used to compare three or more people, places, or things. It’s used to state that the action performed is to the highest degree within a group or of its kind. They are sometimes preceded by the word “the” but not always.

Superlative Adverb Example: Bobby talks the loudest of all the boys.
Superlative Adverb Example: Jill danced the best.

In the opening sentence the superlative adverb form of beautifully was used to compare three or more manners of dress. Most beautifully is the highest degree of dressing beautifully!

Forming a Superlative Adverb

The rules for forming a superlative adverb is rather straightforward. If the adverb has the same form as a one-syllable adjective simply add the suffix –est to the end of the word.

For example:

Superlative Adverb Example: Barry slept the longest.
Superlative Adverb Example: Jack’s bullfrog jumped the highest.
Superlative Adverb Example: Naomi finished the quickest.

Also, just as with forming superlative adjectives, if the adverb ends with a “y” then change the “y” to “i” and then add –est. Like this:

Superlative Adverb Example: Kyle and Lindsey arrived early but Luke arrived the earliest.

However, sometimes adding an –est isn’t appropriate to form a superlative adverb. The vast majority of adverbs end in the suffix –ly and to add another suffix isn’t grammatically correct. Plus, it sounds funny. You wouldn’t say dressed beautifullyest would you? Thankfully, there is a much easier way to show the superlative form of these adverbs. All you have to do to form the superlative adverb for adverbs that end in –ly is precede them with most or least.

Superlative Adverb Example: This computer model operates least efficiently.

Superlative Adverb Examples

It’s often helpful to see adverbs in all their forms in order to get a clear idea of the degrees of comparison. Here is a list of several common adverbs in the positive, comparative, and superlative form.

Positive Comparative Superlative
soon sooner soonest
loud louder loudest
quick quicker quickest
fast faster fastest
long longer longest
hard harder hardest
sweetly more sweetly most sweetly
angrily more angrily most angrily
brightly more brightly most brightly
abruptly more abruptly most abruptly

Irregular Forms

Some adverbs have irregular forms, which means the superlative can’t be created by adding the suffix –est or by using most or least. Here are some such superlative adverb examples:

Many – most

Much – most

Well – best

Bad – worst

Far – farthest/furthest

Little – least

Use these rules and examples to help you with your understanding of the superlative adverb form. Just remember that superlatives compare three or more people, places, or things and they are created with the suffix –est or the use of the words most or least. Then, once you’ve memorized a few irregular forms, you’ll quickly find forming a superlative adverb to be a breeze.
