Adouble superlative is the use of both "most" and the suffix "-est" to form the superlative of an adjectiveinEnglish grammar.[1] This grammatical practice has been contested throughout the history of the English language. The presence of more than one superlative marker is widespread across varieties of English around the world and is also found in other languages.[2] Historically, this construction dates back to Old English. Shakespeare provides numerous examples of double superlatives in his works.[3]
Another famous example of a double superlative used in the works of Shakespeare is in the play, Julius Caesar. Anthony, in his memorialization of Caesar, describing Brutus' stabbing as "the most unkindest cut of all."
