Superlative adjectives are used to compare more than two people or things by indicating which one is the most supreme. Some examples of superlative adjectives include words such as smartest, loudest, most impressive, and least valuable.

Rules for Using Superlative Adjectives

While using superlative adjectives, the following rule is followed:

Noun (subject) + verb + the + superlative adjective + noun (object).

For example:

• His dog ran the fastest of any dog in the race.
• We wear our oldest clothes for gardening.
• This is the smallest box I have ever seen.
• Our house is the largest one in our neighbourhood.
• He is the youngest of the three brothers.

Forming regular comparatives and superlatives:

The form depends on the number of syllables in the original adjective.

One Syllable Adjectives
We add ‘–er’ for comparative and ‘–est’ for superlative

Two Syllable Adjectives
Adjectives with two syllables can form the comparative either by adding -er or by preceding the adjective with more. These adjectives form the superlative either by adding -est or by preceding the adjective with most.

Three or More Syllable Adjectives
Adjectives with three or more syllables form the comparative by putting more in front of the adjective, and the superlative by putting most in front.
