Sic

The typical editorial usage of sic is to inform the reader that any errors in a quotation did not arise from editorial errors in the transcription, but are intentionally reproduced as they appear in the original source being quoted; thus, sic is placed inside brackets to indicate it is not part of the quotation. Sic can also be used derisively to direct the reader's attention to the writer's spelling mistakes and erroneous logic, or to show disapproval of the content or form of the material.
