A double negative occurs when two forms of negation are used in the same sentence. In some languages (or varieties of a language) negative forms are consistently used throughout the sentence to express a single negation, while in others a double negative is used to negate a negation and therefore resolves to a positive. In the former case, triple and quadruple negation can also be seen, which leads to the terms multiple negation or negative concord.
