Jump to answers ↓Superlative Adjectives: Spelling and Irregular Forms
Superlative adjectives are used to compare three or more nouns, showing which one represents the highest or lowest extreme of a specific quality. For example, we typically add -est to short adjectives (like the tallest) but use the most before longer words (like the most expensive).
In this challenge, you will step into the shoes of dramatic food critics, fashion bloggers, and even aliens to apply correct superlative grammar. You will practice spelling changes for short adjectives (such as changing 'y' to 'i' in laziest or doubling consonants in biggest), forming multisyllable superlatives (like most ridiculous), and identifying tricky irregular forms (like best and worst).
You'll work through 12 questions in a variety of single-choice, multi-choice, drop-down, and drag-and-drop formats.

Correct answers
Question 1
Complete the wildlife documentary script about survival in the jungle by matching each blank with the appropriate word.
The cheetah is the fastest runner on the savanna, while the tiny poison dart frog is easily the most dangerous creature in the rainforest.
The cheetah is the fastest runner on the savanna, while the tiny poison dart frog is easily the most dangerous creature in the rainforest.
For short, one-syllable adjectives like "fast", we add "-est" to form the superlative (fastest).
For longer adjectives with three or more syllables like "dangerous", we use "most" before the adjective (most dangerous) instead of adding an ending.
Question 2
The correct answers are Taking the dirt road through the swamp was the worst idea ever! and That is the furthest we have ever driven in a single day.
"Bad," "far," and "good" are irregular adjectives.
The superlative of "bad" is the worst.
The superlative of "far" is the farthest or the furthest.
The superlative of "good" is the best (not "the bestest").
Question 3
The correct answers are fluffiest and best.
For two-syllable adjectives ending in "-y" (like fluffy), change the "y" to "i" and add "-est" to make the superlative (fluffiest). Avoid double superlatives like "most fluffiest."
The adjective "good" is irregular, and its superlative form is best.
Question 4
The correct answers are This is the most delicious burger I have ever eaten! and It is definitely the greasiest meal on the menu.
Long adjectives like "delicious" use the most + adjective to form the superlative.
Adjectives ending in "-y" like "greasy" drop the "y" and add "-iest" (the greasiest).
"Bad" is an irregular adjective; its superlative form is the worst, not "the baddest."
"Friendly" can take "-iest," but using "most" and "-iest" together creates an incorrect double superlative.
Question 5
The correct answers are most boring and longest.
The adjective "boring" has two syllables but doesn't end in "-y," so it uses most to form the superlative (most boring).
The adjective "long" is a short, one-syllable word, so we simply add "-est" to the end (longest).
Question 6
Help the food critic finish her dramatic review of the city's new diner by dragging the correct words into the blanks.
This is officially the worst pie I have ever tasted in my entire life, but ironically, they serve the best coffee in town.

The adjective "bad" has an irregular superlative form: worst. We never say "most bad" or "baddest".
The adjective "good" also has an irregular superlative form: best. We never say "most good" or "goodest".
Question 7
The correct answers are worst and most expensive.
The adjective "bad" is irregular, and its superlative form is worst.
For long adjectives with three or more syllables like "expensive," we form the superlative by adding most before the adjective.
Question 8
The correct answers are The cheetah is the fastest land animal on the planet. and The elephant is the biggest land mammal we found.
Short adjectives usually just add "-est" (fastest).
If a short adjective ends in a single vowel followed by a single consonant (like "big"), you must double the final consonant (biggest).
For adjectives ending in "-y" (like "heavy" and "lazy"), change the "y" to an "i" before adding "-est" (heaviest, laziest). "Most laziest" is an incorrect double superlative.
Question 9

This mansion has the biggest swimming pool in the entire neighborhood, and it is located in the sunniest part of the valley!
This mansion has the biggest swimming pool in the entire neighborhood, and it is located in the sunniest part of the valley!
When a short adjective ends in a single vowel followed by a single consonant (like "big"), we double the final consonant before adding "-est" (biggest).
When a two-syllable adjective ends in "-y" (like "sunny"), we change the "y" to "i" and add "-est" (sunniest).
Question 10

The designer showcased many strange outfits, but that giant hat made of real bananas was definitely the _____ accessory of the night.
The correct answer is most ridiculous.
For long adjectives (usually three or more syllables, like ri-dic-u-lous), we form the superlative by putting "most" before the adjective. We do not add "-est" to the end of long adjectives.
