Superlative adjectives are used to describe an object that has the highest or lowest degree of a quality compared to other objects. To form the superlative of one-syllable adjectives, -est is added to the adjective. For adjectives ending in a consonant-vowel-consonant pattern, the final consonant is doubled before adding -est. For adjectives of more than one syllable, more or most is placed before the adjective to form the comparative and superlative.
