The term "false prophet" refers to someone who claims to have divine inspiration or knowledge, but whose predictions or teachings turn out to be false. In a religious context, it can refer to individuals who claim to speak on behalf of God or a higher power, but whose messages are not genuine or accurate. The phrase is often used in the Bible to describe people who lead others astray with their prophecies or teachings that contradict true divine revelation. In modern times, the term can also be applied to individuals who make grandiose claims about their abilities or insights but whose predictions do not come true.
