An award is something given to a person, a group of people, or an organization to recognize their excellence in a certain field; a certificate of excellence. Awards are often signified by trophies, titles, certificates, commemorative plaques, medals, badges, pins, or ribbons. An award may carry a monetary prize given to the recipient; for example, the Nobel Prize for contributions to society or the Pulitzer Prize for literary achievements. An award may also simply be a public acknowledgment of excellence, without any tangible token or prize.
