Comparatives and superlatives: choose the right form
まずは要点
A comparative adjective expresses a greater or smaller degree, as in larger or less expensive. A superlative expresses the highest or lowest degree within a group, as in the largest or the least expensive. More than one member can share that extreme.
ポイント
- Use a comparative to express a difference and a superlative to identify an extreme within a group.
- Choose the adjective form carefully, use than for a direct comparison, and check whether the noun phrase needs the, a possessive, or another determiner.
- Use a comparative to compare one person or thing with another, or with a group.

基本から解説を読む
Choose a comparison or an extreme within a group
Decide what relationship you want to express. A comparative contrasts one item with another item or a group: this van is larger than the others. A superlative identifies an extreme: this is the largest van. Comparatives are usual for a pair, but the number of items alone does not determine every choice.
-
Our morning train is faster than the express bus.
この表現を使う理由： Faster compares two specific transport options.
-
The midnight service is the fastest option of all four departures.
この表現を使う理由： The fastest selects one service from a group of four departures.
-
This office desk is wider than my previous table.
この表現を使う理由： Wider compares two individual pieces of furniture.

Which sentence correctly compares two company vans?
答え： The white van is larger than the silver van.
答えを見る
答え： The white van is larger than the silver van.
Larger is the usual comparative of large. Than introduces the van being compared with it.
Attach Endings to One-Syllable Adjectives
Most adjectives with only one spoken beat form their comparative with -er and their superlative with -est. Do not place more or most in front of these short words during normal conversation. Adding extra words creates clumsy repetition that sounds unnatural to native listeners. For adjectives ending in a silent e, simply add -r for the comparative and -st for the superlative to keep the spelling tidy.
-
My new apartment is colder in winter than my old flat.
この表現を使う理由： Cold has one syllable, so it takes -er rather than more cold.
-
This jacket is the nicest coat on the clothing rack.
この表現を使う理由： Nice ends in silent e, so it simply adds -st for the superlative.
-
Her commute is longer than mine during rush hour.
この表現を使う理由： Long takes -er because it contains a single spoken beat.

Which option correctly completes the phrase: This hallway is ___ of all three corridors?
答え： the widest
答えを見る
答え： the widest
Wide has one syllable and ends in e, so it forms the superlative by adding -st with the definite article.
Adjust Spelling for Final Consonants and Y
In a one-syllable adjective ending in one vowel letter and one consonant, usually double the final consonant before -er or -est, as in big, hot, and thin. Do not double w, x, or y. After a consonant plus y, change y to i before adding the ending.
-
The kitchen is bigger than the dining room.
この表現を使う理由： Big doubles the letter g before adding -er to preserve the short vowel.
-
Thursday was the hottest afternoon of the summer.
この表現を使う理由： Hot doubles the final t before the superlative suffix -est.
-
Our warehouse team is busier today than yesterday.
この表現を使う理由： Busy changes y to i before adding the comparative ending -er.

答え： The brown carton is heavier than the white box.
答えを見る
答え： The brown carton is heavier than the white box.
Adjectives ending in consonant plus y change y to i before adding -er.
Use More and Most with Longer Adjectives
Adjectives with three or more spoken beats do not take suffix endings like -er or -est. Instead, place more in front of the base word to compare two items, and place the most in front to single out one item from a larger collection. This pattern also applies to two-syllable adjectives that end in suffixes such as -ful, -less, -ing, or -ed. Never combine an ending and an adverb together on the same root.
-
Online banking is more convenient than visiting the branch.
この表現を使う理由： Convenient has three syllables and takes more in this comparison.
-
This spreadsheet is the most useful tool on my computer.
この表現を使う理由： Useful ends in the suffix -ful and takes the most for group comparison.
-
Our second design proposal is more expensive than the first.
この表現を使う理由： Expensive has three syllables, so more indicates the higher degree.

Which sentence compares two software applications accurately?
答え： This program is more powerful than the old system.
答えを見る
答え： This program is more powerful than the old system.
Powerful has three syllables and takes more to form a comparative with than.
Recognize Adjectives That Allow Both Patterns
Some two-syllable adjectives allow both an -er form and a form with more. Narrower and more narrow are both possible. Which sounds more natural depends on the adjective, the sentence, and usage; the choice is not a simple rule separating speech from formal writing.
-
Our new printer setup is simpler than the old procedure.
この表現を使う理由： Simpler uses the suffix ending on a two-syllable adjective.
-
The technician gave a more simple explanation in the summary.
この表現を使う理由： More simple uses the analytical form with the same base meaning.
-
The corner desk is the quietest spot in the open office.
この表現を使う理由： Quietest selects the highest degree of quiet using an -est suffix.

答えを見る
答え： Both 'narrower' and 'more narrow' are acceptable comparative forms.
Narrow is a two-syllable adjective that accepts either the -er ending or more.
Memorize Common Irregular Comparison Forms
Some adjectives have irregular comparison forms. Good becomes better and best; bad becomes worse and worst. For physical distance, use farther or further. Further can also mean additional, as in further information. Use these forms instead of adding regular endings.
-
Today's sales figures are better than last week's results.
この表現を使う理由： Better is the irregular comparative form of good.
-
That was the worst commute we experienced all month.
この表現を使う理由： The worst is the irregular superlative form of bad.
-
Please contact our office if you require further assistance.
この表現を使う理由： Further means additional when referring to non-physical matters.

答えを見る
答え： The traffic delay today was worse than yesterday.
Bad is an irregular adjective whose comparative form is worse.
Connect Comparative and Superlative Structures
When you compare two elements explicitly, connect them using the conjunction than, never the time adverb then. Superlatives modifying a noun normally require the definite article the, although possessive pronouns such as my, our, or their can take its place. In casual spoken English, the article is occasionally omitted after linking verbs when no noun follows, but keeping the maintains clarity across both speech and professional writing.
-
This laptop runs faster than my desktop workstation.
この表現を使う理由： Faster is a comparative adverb describing how the laptop runs; than introduces the comparison.
-
She is our best engineer on the software development team.
この表現を使う理由： The possessive pronoun our takes the place of the definite article the.
-
The blue chair is the most comfortable seat in the room.
この表現を使う理由： The definite article the introduces the superlative phrase before seat.

答え： The conference room is cooler than the hallway.
答えを見る
答え： The conference room is cooler than the hallway.
Than is the conjunction used to introduce the second element of a comparison.
Recognize Weak Syllables in Spoken Sentences
In natural spoken English, connecting words such as than and the are unstressed. Speakers reduce than to a quick weak sound resembling /ðən/, while the sounds like /ðə/ before consonant sounds. Meanwhile, the comparative ending -er or superlative ending -est carries lighter stress than the root word itself. Focusing on the stressed root allows you to identify the core meaning even when functional syllables blur in fast conversation.
-
The train is quicker than the bus.
この表現を使う理由： Quick receives main stress, while -er and than reduce to weak unstressed syllables.
-
It was the darkest night of the winter season.
この表現を使う理由： Dark takes sentence stress while the and -est remain short and unstressed.
-
Her desk is cleaner than mine.
この表現を使う理由： Clean carries emphasis while -er and than link together smoothly.

「Comparatives and superlatives: choose the right form」に関する質問
What is the difference between farther and further?
Farther and further both describe physical distance in everyday English, and speakers frequently treat them as interchangeable in that context. However, only further can express figurative degree, additional time, or extra information. For example, when you ask for more details or extra training, always select further.
The warehouse is farther away than our retail storefront.
Please email our support desk if you need further clarification.
Can I combine more with an irregular adjective like better or worse?
No, combining more with words like better or worse creates a double comparative, which is grammatically incorrect in standard English. Because better already means more good and worse already means more bad, adding more produces redundant phrasing. Use the single word better or worse alone.
This software update runs better on our workstations.
The stormy weather created worse driving conditions tonight.
Is the word the always required before a superlative adjective?
A superlative before a noun often uses the: 'the tallest building'. A possessive can take its place: 'my best friend'. When there is no following noun, the pattern varies. 'I am happiest at home' is natural without the. Check the whole noun phrase rather than adding the automatically.
He is our most experienced project manager.
This quiet corner is the best place to read.
How do I know whether a two-syllable adjective takes -er or more?
Two-syllable adjectives ending in y almost always change y to i and add -er, such as heavier or friendlier. Adjectives ending in suffixes like -ful, -less, or -ous strictly take more, such as more careful. A small group of neutral two-beat words like quiet or simple accepts either pattern.
My new laptop bag is heavier than my old backpack.
Please be more careful when carrying delicate equipment.
