A superlative is a form of an adjective or adverb used to indicate the highest degree of comparison between two or more things. In grammar, superlatives are used to describe the quality, quantity, or intensity of a noun or verb in the most extreme way possible. Superlatives are formed in different ways, depending on the word being modified. For example, one-syllable adjectives typically add "-est" to the end, while longer adjectives use "most" or "least" before the word. Superlatives are commonly used in everyday language to describe people, places, things, and events in a highly favorable or unfavorable way, such as "the best restaurant in town" or "the worst movie ever made."
