Microsoft Office can use multiple custom dictionaries to check the spelling of documents. Whenever you add any word/specialized term to dictionary, a custom dictionary is created, and additional supplement added to main dictionary with extra words, terms; which means the main dictionary remains intact.
For some reason, if you want to restore the Dictionary to factory setting, then this article describes how to reset Microsoft Office Dictionary by deleting custom dictionaries.
