 In other contexts, the terms trump card or to trump can refer to any sort of action, authority, or policy which automatically prevails over all others.The English word "trump" derives from "trionfi", a type of 15th-century Italian playing cards, from the Latin "triumphus" "triumph, victory procession", ultimately (via Etruscan) from Greek θρίαμβος, the term for a hymn to Dionysus sung in processions in his honour.
