Quick Answer

In Microsoft Word, you can add words to the custom dictionary by right-clicking the flagged word and selecting "Add to Dictionary," which saves the term to a file named CUSTOM.DIC. This prevents repeated spell-check warnings for that word across all documents using the same dictionary. The custom dictionary supports thousands of user-added entries.
