What Are Comparative and Superlative FormsComparative and superlative forms are used to describe differences between things and to show how one thing measures against others. They help you answer simple questions such as which is bigger, which is faster or which is the most interesting. Comparative forms show a difference between two people, places or things.
Superlative forms show the highest or lowest degree among three or more.
Comparatives highlight contrast. Superlatives highlight ranking. Both are essential for clear, descriptive English and appear often in everyday conversation, writing, and test questions. How to Form Comparatives and SuperlativesThe easiest way to form comparative and superlative words is to follow a few simple patterns. Most adjectives and adverbs change in predictable ways, and once you know the rules, you can apply them almost automatically. Forming Comparatives and Superlatives for One Syllable WordsMost one syllable adjectives take the endings er for the comparative and est for the superlative. Examples:
If the word follows a consonant vowel consonant pattern, double the final consonant. Examples:
Forming Comparatives and Superlatives for Two Syllable WordsTwo syllable words can follow two possible patterns. If the word ends in the letter y, change the y to i and add er or est.
If the word does not end in y, it usually forms the comparative with more or less, and the superlative with most or least.
Some two syllable adjectives accept either pattern. In these cases, use the form that sounds natural in context.
Forming Comparatives and Superlatives for Three or More SyllablesAll adjectives with three or more syllables use more and most. Examples:
These longer words do not take the er or est endings. Spelling Rules You Should KnowThese spelling patterns will help you avoid common mistakes. If the adjective ends in e, only add r or st. Examples:
If it ends in y, change the y to i before adding er or est. Examples:
If it follows the consonant vowel consonant pattern, double the final consonant. Examples:
Irregular FormsSome common words do not follow the standard patterns. These must be memorized.
Comparatives and Superlatives for AdverbsAdverbs follow many of the same patterns as adjectives, but they are often simpler to form. Most adverbs do not take er or est endings. Instead, they use the words more and most to show comparison. Most Adverbs Use More and MostIf the adverb ends in ly, use more for the comparative and most for the superlative. Examples:
Many of these words are an adverb of manner, so learning how they behave will make the comparison patterns easier to understand. Short Adverbs Add er and estA small group of short adverbs behaves like short adjectives. These usually come from adjectives that do not end in ly. Examples:
Irregular AdverbsSome very common adverbs change completely and do not follow regular patterns.
These are the same irregular patterns used by their adjective forms. Adverbs in SentencesComparatives with adverbs often compare how someone performs an action.
Superlatives show the highest performance among several people or things.
When to Use Comparatives vs SuperlativesThe quickest way to decide which form to use is to look at how many things you are comparing. Comparatives are used for two items. Superlatives are used for three or more. Everything else builds on this simple idea. Use Comparatives to Compare Two ThingsComparatives show a difference between one thing and another. Examples:
Comparatives often appear with the word than, but not always.
Use Superlatives to Compare Three or More ThingsSuperlatives identify the highest or lowest degree within a group. Examples:
Superlatives usually come after the word the.
Choosing the Right Form in Everyday UseIf you find yourself comparing two choices, think comparative.
If you are ranking several choices, think superlative.
Common Mistakes and How to Fix ThemMost errors with comparatives and superlatives happen because the wrong pattern is used. Learning a few common mistakes will help you avoid them and use these forms with confidence. Using more with er or most with estDo not combine the two patterns.
Short adjectives take er and est without extra words. Using the wrong pattern for long wordsLong adjectives do not use er or est.
If the adjective has three or more syllables, always choose more or most. Not changing y to i before adding er or estTwo syllable adjectives ending in y must change the spelling.
This spelling change makes the word easier to read and pronounce. Incorrect doubling of the final consonantDouble the final consonant only when the word follows a consonant vowel consonant pattern.
Check the original spelling before adding endings. Confusing irregular formsIrregular words do not follow predictable rules.
These forms must be memorized. The same idea applies to regular and irregular verbs, which also follow predictable or unpredictable patterns you need to remember. Using than with superlatives or the with comparativesSignal words help you pick the right form.
