There are three basic forms for adjectives and adverbs: the basic form, the comparative form, and the superlative form. There are two basic rules to remember when using adjectives and adverbs in the comparative and superlative forms.
Rule One: For positive comparisons, to form the comparative, –er and more are used, and to form the superlative, –est and most are used. For negative comparisons, to form the comparative, –er and less are used, and to form the superlative, –est and least are used.
Rule Two: When comparing two items with one-syllable words, use –er . When comparing two items with words of more than one syllable, use more or less before the word. Never use –er and more or less at the same time. When comparing three or more items with one-syllable words, use –est . When comparing three or more items with words of more than one syllable, use most or least before the word. Never use –est and most or least at the same time.
Positive Comparisons: One-syllable words
Basic Form: tall
Comparative Form: tall er = taller
Superlative Form: tall est = tallest
Positive Comparisons: Words of more than one syllable
Basic Form: difficult
Comparative Form: difficult more = more difficult
Superlative Form: difficult most = most difficult
Negative Comparisons: One-syllable words
Basic Form: tall
Comparative Form: tall less = less tall
Superlative Form: tall least = least tall
Negative Comparisons: Words of more than one syllable
Basic Form: difficult
Comparative Form: difficult less = less difficult
Superlative Form: difficult least = least difficult
There are exceptions to the adjective and adverb rule. The adjectives good and bad and the adverbs well and badly do not follow the conventional rules for adjectives and adverbs in the comparative and superlative forms. The adjectives good and bad and the adverbs well and badly are irregular adjectives and adverbs, meaning they form the comparative and superlative differently than most other adjectives and adverbs.
For an easy way to remember when to use the adjectives good and bad and the adverbs well and badly in the comparative form, follow these rules. When comparing two items, use better or worse. Never use more and better or worse at the same time. When comparing three or more items, use best or worst. Never use most and best or worst at the same time.

Correct: The youngest child plays piano worse than her eldest sibling.
There are two types of errors involving adjectives and adverbs in the comparative and superlative forms. One error occurs when both methods for forming the comparative and superlative forms are used—for example, using both –er and more or less to compare two items or using both –est and most or least to compare three or more items.
Incorrect: The youngest child is more taller than her eldest sibling.
Correct: The youngest child is taller than her eldest sibling.
Another error occurs when the comparative and superlative forms are used with the wrong number of items. The comparative form is used when two items are being compared. The superlative form is used when three or more items are being compared.
Incorrect: The banker made the more difficult decision in the bank’s history.
Correct: The banker made the most difficult decision in the bank’s history.
Following these basic rules for adjectives and adverbs in the comparative and the superlative forms will make using adjectives and adverbs hassle-free.
