Irregular Comparison of Adjectives

The English grammatical morphemes, particularly in the formation of comparative adjectives, can be tricky for English language learners due to the irregularity of the rules. When learners do not explore the irregular comparison of adjectives, they might end up making mistakes in their writing and speaking.

On the bright side, there are only a few irregular comparisons of adjectives that learners need to remember. The most common ones are good, bad, far, and little. In this blog, we will discuss the irregular comparison of these adjectives, use them in sentences, study their meaning, and also look at some examples.

What are Irregular Adjectives?

Irregular adjectives are words that don’t follow the regular convention of forming comparative and superlative forms. In regular adjectives, most monosyllabic and two-syllable adjectives add the suffix “-er.” Long adjectives carry the determiner “more” before them as in “more spacious,” “more entertaining,” and “more curious.” 

For the superlative adjectives, most monosyllabic and two-syllable words add the suffix “-est” on its end. Moreover, long adjectives use the determiner “most” to form the superlative form. Examples are “most expensive,” “most beautiful,” and “most delicious.”

When learners encounter irregular adjectives, they might make the mistake of converting them following the rules for regular adjectives. For instance, a beginner might conjugate “good” into “gooder,” and “goodest.” However, since irregular adjectives are special cases, they don’t follow the same rules.

Adjectives with Different Meanings

Another challenge irregular adjectives pose is some irregular adjectives have different meanings. There are four sets of irregular adjectives in question regarding this.

1. Farther vs Further

“Farther” and “further” pertains to the distance of something. Hence, some learners use them interchangeably. However, those words differ in meaning. “Farther” is used for physical distance and “further” is appropriate for figurative distance.

For example:

(1) If you take the left turn, you will be farther away from your destination.

(2) I fell further away from him after knowing he lied to me.

The first sentence speaks of the distance from one place to another. Thus, “farther” is used. In the second sentence, the statement speaks of emotional distance that cannot be measured. Hence, “further” is appropriate for this reason.

2. Bad – Worse – Worst

The positive adjective “bad” could mean three things. It describes an action that is not agreeable (e.g., stealing is bad). Moreover, it could mean feeling unwell, as in “I feel bad because of a fever.”  Lastly, it describes something of poor quality. For example, “He made a bad design for my living room.” As such, it follows that its comparative and superlative degrees could mean any of the three above.

3. Good vs Well

The word “good” generally functions as an adjective. However, “well” functions as both an adjective and an adverb. This is where the confusion stems. To know whether you are using “well” as an adjective, it’s important to examine the verb that precedes it.

For example: 

(1) “Well” as an adjective: He feels well today after his surgery. → He is well today after his surgery.

(2) “Well” as an adverb: He performed well in his exams. 

The verb (feels) in the first sentence functions as a stative verb. It shows the state of being of a subject. That’s why when it was replaced by the be-verb “is,” the meaning of the sentence didn’t change. Therefore, “well” is an adjective in the first sentence.

In contrast, the verb (performed) in the second sentence is a dynamic verb. As such, it shows an action or process instead of a state of being. “Well” modifies how the subject performed. Hence, it’s an adverb in this example.

4. In as an Adjective 

“In” is one of the English words that take different functions. As an adjective, it means something or someone that is trendy, popular, or famous.

For example: 

  • Cropped cardigans are in this time. I need to buy one.
  • Taylor’s new album is in with Gen Z and millennials.
  • Mom’s jeans are in and trendy today.

Unlike “bad,” the comparative and superlative forms of “in” does not carry a positive meaning. “Inner” and “innermost” refers to surfaces or position of something. Those words don’t refer to trends.

Remember this analogy to easily remember the difference of the degrees of adjectives:

Positive: one noun

Comparative: two nouns

Superlative: three or more nouns
Incorrect: Your shirt is the best than mine.

Correct: Your shirt is better than mine.

Use the comparative degree since there are two things being compared.

Incorrect: Your shirt is better among the rest.

Correct: Your shirt is the best among the rest.

Since the subject’s shirt is being compared to a population, it is proper to use a superlative adjective.
Converting irregular adjectives using the regular adjective rulesFollowing the English grammar rules, combining “most” or “least” and an already conjugated superlative adjective is wrong.

Some learners use do this when speaking informal English.
Only use the determiner “most” when the adjective is not irregular and follows the other convention of converting regular adjectives.Incorrect: He is the most humblest person I know.

Correct: He is the humblest person I know.

Incorrect: She is the most prettiest girl in the world.

Irregular Comparison of Adjectives Frequently Asked Questions

The three comparisons of adjectives are positive, comparative, and superlative. Positive comparison describes one thing or person. Comparative takes into consideration two things or people. The superlative degree expresses which among three or more nouns is the best or the least.

Examples of irregular comparisons include good-better-best, bad-worse-worst, far-farther/further-farthest/furthest. Here are a few examples:

Positive: Jim is a good speaker
Comparative: John is a better speaker than Jim.
Superlative: Jade is the best speaker among the three.

The three most common irregular comparative and superlative adjectives are worse-worst, better-best, and more-most. Here are examples of how to use them in sentences:
(1) Comparative: Compared to me, my sister is the worse cook.

Superlative: The casserole she served was the worst thing I have ever tasted.

(2) Comparative: I cook better than my sister.

Superlative: I cook oriental dishes the best.

(3) Comparative: Laika has three years more experience in computer programming than Michael.

Superlative: Liz has the most experience in computer programming among the rest.

The comparative adjective for “good” is “better.” Here is an example sentence:

Positive: Sandra is a good painter.
Comparative: Meryl paints better than Sandra.

Regular adjectives conform to the standard rules of English grammar and can be conjugated by adding the suffix “-er” for comparative and “-est” for superlative at the end of the word. Irregular adjectives do not follow the standard rules and must be memorized.
