A rumor (American English) or rumour (British English; see spelling differences) (origin word from Latin is 'rumorem', or noise) is "a tall tale of explanations of events circulating from person to person and pertaining to an object, event, or issue in public concern."
In the social sciences, a rumor involves a form of a statement whose veracity is not quickly or ever confirmed. In addition, some scholars have identified rumor as a subset of propaganda. Sociology, psychology, and communication studies have widely varying definitions of rumor.
Rumors are also often discussed with regard to "misinformation" and "disinformation" (the former often seen as simply false and the latter seen as deliberately false, though usually from a government source given to the media or a foreign government). Rumors thus have often been viewed as particular forms of other communication concepts.
In 1996 in Colombia, a panic was caused by a Christian fundamentalist rumour that the Antichrist was arriving and would mark or remove any unbaptized children.
The Internet has become the prime medium for the circulation of rumours on every conceivable subject, notably with regard to conspiracy theories.
