Transformation of Degree of Comparison

Adjectives are used to modify nouns and pronouns. Adjectives are also used to make comparisons. We call it degree of comparison.

Adjectives take three forms when they are used to make comparisons. They are:

  • Positive Degree
  • Comparative Degree
  • Superlative Degree

Positive Degree

Positive degree is the simple form of adjectives and adverbs. For example, the adjectives and adverbs in the following sentences are in the positive forms. Remember that we use positive forms of adjectives when no comparison is made

  • A tiger is a large animal. 
  • It can run fast
  • A dog cannot run as fast as a tiger.

Comparative Degree

Comparative forms of adjectives are mainly formed by adding -er to the positive or primary forms of adjectives. We use comparative degree when comparison is made between two nouns or pronouns  and one becomes higher or lower in degree. Note that comparative degrees follow than.

  • A tiger is larger than a dog.
  • It runs faster than a cat.
  • It is braver than a crocodile.

Superlative Degree

    Superlative forms of adjectives are mainly formed by adding -est to the positive or primary forms af adjectives. We use superlative degree when comparasion is made between more than two nouns or pronouns  and one becomes highest or lowest in degree. We always use the before a superlative degree.

    • The whales are the largest animal in the world.
    • April is the cruelest month.
    • Tanha is the tallest girl in the class.

    Rule 1. Interchange of Comparative & Positive Degrees

    It is possible to interchange positive and comparative degree without changing the meaning of the sentence. Read the following examples first. Note that both the sentences have the same meaning, but different form. 

    (a) Comparative: Jessica is older than Linda.
    Positive: Linda is not as old as Jessica.
    (b) Comparative: A cow is larger than a cat.
    Positive: A cat is not so large as a cow.

    Grammar Explanation

    (i) We use than after comparative.

    (ii) We use so or as before positive. After the positive degree, we use as.

    Rule 1 in Table:
