According to standard English grammar, a double negative used to express a single negative, such as I don't know nothing (rather than I don't know anything), is incorrect. The rules dictate that the two negative elements cancel each other out to give an affirmative statement, so that, logically, I don't know nothing would be interpreted as I know something. In practice this sort of double negative is widespread in dialect and other non-standard usage and rarely gives rise to confusion as to the intended meaning. Double negatives are standard in certain other languages such as Spanish and Polish and they have not always been unacceptable in English, either. The double negative was normal in Old English and Middle English and did not come to be frowned upon until some time after the 16th century, when attempts were made to relate the rules of language to the rules of formal logic. The double negative can be used in speech or in written dialogue for emphasis or other rhetorical effects. Modern (correct) uses of the double negative give an added subtlety to statements: saying I am not unconvinced by his argument suggests reservations in the speaker's mind that are not present in its logical equivalent: I am convinced by his argument. However, the double negative should be used judiciously because it may cause confusion or annoy the reader
