A false statement, also known as a falsehood, falsity, misstatement or untruth, is a statement that is false or does not align with reality. This concept spans various fields, including communication, law, linguistics, and philosophy. It is considered a fundamental issue in human discourse. The intentional dissemination of misstatements (disinformation) is commonly termed as deception or lying, while unintentional inaccuracies may arise from misconceptions, misinformation, or mistakes.
Although the word fallacy is sometimes used as a synonym for false statement, that is not how the word is used in most formal contexts.
