superlative

In grammar, the superlative is the form of an adverb or adjective that of the adverb or adjective being used that is greater than any other possible degree of the given descriptor. English superlatives are typically formed with the suffix -est (e.g. healthiest, weakest) or the word most (most recent, most interesting). One preposition, near, also has a superlative form, as in Find the restaurant nearest your house.
