Much Ado About Nothing is a comedy by William Shakespeare thought to have been written in 1598 and 1599. The play was included in the First Folio, published in 1623. Through "noting" (sounding like "nothing", and meaning gossip, rumour, overhearing), Benedick and Beatrice are tricked into confessing their love for each other, and Claudio is tricked into believing that Hero is not a maiden (virgin). Claudio therefore rejects Hero at the altar. However, Hero is vindicated, and marriages are arranged for both pairs.
