The comparison of adjectives involves expressing the degree of a quality by comparing one person, thing, or action to another.

Grammar - Comparison of adjectives

There are three degrees of comparison: positive, comparative, and superlative.

Positive degree:

Used when no comparison is made. It simply describes a quality.

Example:

She is a good singer.

Comparative degree:

Used to compare two people, things, or actions.

Structure:

For one-syllable adjectives: [adjective] + “-er

Example:

The cat is faster than the dog.

For two-syllable adjectives ending in –y: Change –y to –i and add “-er.”

Example:

The city is busier than the town.

For two or more syllable adjectives: Use “more” before the adjective.

Example:

The movie is more interesting than the book.

Superlative degree:

Used to compare three or more people, things, or actions.

Structure:

For one-syllable adjectives: [adjective] + “-est

Example:

She is the tallest girl in the class.

For two-syllable adjectives ending in –y: Change –y to –i and add “-est.”

Example:

I am the happiest person in this party.

For two or more syllable adjectives: Use “most” before the adjective.

Example:

It is the most beautiful place I’ve ever seen.

Irregular comparisons:

Some adjectives have irregular forms in the comparative and superlative degrees:

GoodBetter (comparative) → Best (superlative)

BadWorse (comparative) → Worst (superlative)

Usage tips:

Comparisons with “Than”:

Comparative degree is often used with “than” to introduce the second element being compared.

Example:

She is smarter than her brother.

Superlatives and “The”:

Superlatives are usually preceded by “the.”

Example:

This is the best cake I’ve ever tasted.

Double comparisons:

Avoid using double comparatives or superlatives (e.g., “more taller” or “most fastest“). Choose one form.

Incorrect: He is more taller than his friend.

Correct: He is taller than his friend.

Common mistakes to avoid:

Incorrect: This is the most unique piece of art.

Correct: This is a unique piece of art. (Avoid using superlatives for absolute qualities like “unique.”)

Incorrect: She is more smarter than I am.

Correct: She is smarter than I am.
