Manuscript marking is a process used by editors and proofreaders to make corrections and notes on written documents. The two most common manuscript markings are STET and DELE. STET is an abbreviation for the Latin phrase 'stetit, ' which means 'let it stand.' This marking is used to indicate that no changes should be made to the text. DELE is an abbreviation for the Latin phrase 'deleatur, ' which means 'delete it.' This marking is used to indicate that the text should be removed from the document.
