What does the term "addendum" refer to?

The term "addendum" specifically refers to a supplemental section that is added to a book or contract. In the context of legal documents and agreements, an addendum is used to provide additional information or clarify stipulations without altering the original text of the contract. This allows parties involved to expand on or modify certain terms without creating a new agreement entirely.

In the context of books, an addendum might include updates, corrections, or supplementary material that enhances the reader's understanding or provides more recent information about the subject matter. Its primary function is to add detail or context while maintaining the integrity of the main document or text.

This understanding highlights the relevance and importance of an addendum in both legal and literary contexts, affirming that it is not a standalone contract nor a main part of a book but rather an enhancement to existing documents.
