Degrees of comparison

Introduction to Degrees of Comparison

In English, we often want to describe qualities or characteristics of people, places, or things. For example, we might say a car is fast, a student is smart, or a mountain is high. These describing words are called adjectives. Sometimes, we want to compare these qualities between two or more things. For example, "This car is faster than that one," or "Mount Everest is the highest mountain in the world."

To show these differences in degree or level, adjectives and some adverbs change their form. These changes are called Degrees of Comparison. There are three main degrees:

  • Positive Degree: The basic form of the adjective or adverb, showing a quality without comparison. (e.g., fast, tall, beautiful)
  • Comparative Degree: Used to compare two things, showing a higher or lower degree of a quality. (e.g., faster, taller, more beautiful)
  • Superlative Degree: Used to compare three or more things, showing the highest or lowest degree of a quality. (e.g., fastest, tallest, most beautiful)

In this chapter, we will learn how to form and use these degrees correctly, understand common exceptions, and avoid typical mistakes.

Types of Degrees of Comparison

Let's explore each degree in detail with examples.

Examples of Degrees of Comparison
Adjective Positive Degree Comparative Degree Superlative Degree
Fast fast faster fastest
Tall tall taller tallest
Beautiful beautiful more beautiful most beautiful
Good good better best

Positive Degree: This is the simple form of the adjective or adverb. It describes a quality without making any comparison.

Comparative Degree: This form is used when comparing two things. We often add -er to short adjectives or use more before longer adjectives.

Superlative Degree: This form is used when comparing three or more things. We usually add -est to short adjectives or use most before longer adjectives.

Formation Rules for Degrees of Comparison

How do we form the comparative and superlative degrees? The rules depend on the number of syllables in the adjective and some spelling patterns.

graph TD    A[Start with adjective] --> B{Number of syllables?}    B -->|One syllable| C[Add -er for comparative, -est for superlative]    B -->|Two syllables ending with -y| D[Change y to i, add -er/-est]    B -->|Two syllables (other endings)| E[Use more/most before adjective]    B -->|Three or more syllables| F[Use more/most before adjective]    C --> G[Examples: fast -> faster -> fastest]    D --> H[Examples: happy -> happier -> happiest]    E --> I[Examples: careful -> more careful -> most careful]    F --> J[Examples: beautiful -> more beautiful -> most beautiful]

One-syllable adjectives: Usually, add -er for comparative and -est for superlative.

Two-syllable adjectives ending in -y: Change the y to i and add -er or -est.

Two or more syllables (except those ending in -y): Use more for comparative and most for superlative before the adjective.

Irregular adjectives: Some adjectives do not follow these rules and have unique forms (e.g., good -> better -> best).

Worked Example: Forming Degrees of 'Happy'

Example 1: Form Degrees of 'Happy' Easy
Form the comparative and superlative degrees of the adjective happy.

Step 1: Identify the number of syllables. "Happy" has two syllables and ends with -y.

Step 2: Change the y to i before adding suffixes.

Step 3: Add -er for comparative: happier.

Step 4: Add -est for superlative: happiest.

Answer: Positive: happy, Comparative: happier, Superlative: happiest.

Worked Example: Using Irregular Adjectives

Example 2: Irregular Adjectives Medium
Write the positive, comparative, and superlative forms of the adjectives good, bad, and far.

Step 1: Recognize these adjectives are irregular and do not follow usual suffix rules.

Step 2: Write their forms:

  • Good -> better -> best
  • Bad -> worse -> worst
  • Far -> farther/further -> farthest/furthest

Note: Both "farther" and "further" are acceptable comparative forms of "far," with subtle differences in usage.

Answer: These irregular forms must be memorized for correct usage.

Worked Example: Choosing Correct Degree in Sentences

Example 3: Correct Degree Usage Medium
Choose the correct form of the adjective in the sentence:
"This is the (fast, faster, fastest) car in the showroom."

Step 1: Identify how many things are being compared. Here, the car is compared with all cars in the showroom (more than two).

Step 2: Use the superlative degree for comparison among three or more things.

Step 3: The superlative form of "fast" is "fastest".

Answer: "This is the fastest car in the showroom."

Worked Example: Form Degrees of 'Tall'

Example 4: Form Degrees of 'Tall' Easy
Write the positive, comparative, and superlative forms of the adjective tall.

Step 1: "Tall" is a one-syllable adjective.

Step 2: Add -er for comparative: taller.

Step 3: Add -est for superlative: tallest.

Answer: Positive: tall, Comparative: taller, Superlative: tallest.

Worked Example: Avoiding Double Comparatives

Example 5: Avoiding Double Comparatives Hard
Identify and correct the error in the sentence:
"This exam is more easier than the last one."

Step 1: Notice that "easier" already contains the comparative suffix -er.

Step 2: The word "more" is incorrectly used with "easier," creating a double comparative.

Step 3: Remove "more" to correct the sentence.

Correct sentence: "This exam is easier than the last one."

Answer: Avoid using "more" with adjectives that already have -er suffix.

Quick Tip: For adjectives ending with y, always change y to i before adding -er or -est. For example, happy -> happier -> happiest.

Tips & Tricks

Tip: For one-syllable adjectives, usually add -er and -est for comparative and superlative forms.

When to use: Simple adjectives like fast, tall, small.

Tip: Use more and most with adjectives having two or more syllables, especially those ending with -ful, -ous, -ing.

When to use: Adjectives like beautiful, dangerous, interesting.

Tip: Memorize irregular adjective forms separately, such as good -> better -> best.

When to use: During practice or exams when encountering irregular adjectives.

Tip: Avoid double comparatives like more better or most fastest.

When to use: While writing or correcting sentences under exam conditions.

Tip: Use than after comparative degree and the before superlative degree.

When to use: When constructing comparative and superlative sentences.

Common Mistakes to Avoid

❌ Using double comparatives like "more better" or "more faster".
✓ Use either "better" or "more good" (though "more good" is incorrect, so "better" is preferred).
Why: Students try to emphasize comparison but incorrectly combine suffix and "more".
❌ Using superlative degree when comparing only two things.
✓ Use comparative degree with "than" when comparing two items.
Why: Confusion between comparative and superlative usage.
❌ Incorrect spelling changes, e.g., "happier" spelled as "happyer".
✓ Change "y" to "i" before adding suffixes for adjectives ending with "y".
Why: Lack of knowledge of spelling rules.
❌ Using "the" with comparative degree.
✓ Use "the" only with superlative degree.
Why: Misunderstanding article usage with degrees of comparison.
❌ Confusing adjectives and adverbs in degrees of comparison.
✓ Identify whether the word modifies a noun (adjective) or verb/adjective/adverb (adverb) and apply correct degree forms.
Why: Lack of clarity on parts of speech.
