addendum
An "addendum" is a document or section added to the end of a primary document, such as a book, contract, or report. It provides additional information, clarifications, or updates that were not included in the original text. Addendums are often used to enhance understanding or to address changes that occur after the initial document is completed.
In legal contexts, an addendum can modify or expand upon the terms of a contract. For example, if new terms are agreed upon after a real estate deal is signed, an addendum can be created to outline these changes. This ensures that all parties have a clear understanding of the updated agreement.
