Question details

Product: Microsoft Word for Mac
Device & OS: macOS
Scenario: Opening existing documents in Microsoft Word for Mac after migrating from or uninstalling older software versions.
Observed behavior: Word repeatedly asks about a dictionary or Office 2011 upon opening files, even though Office 2011 has not been used for a long time.

Before you start

Before modifying any system folders or moving files to the Trash, ensure you have backed up or relocated any personal documents that might be saved inside the legacy Office 2011 folder.

Solution 1Recommended

Remove the Legacy Office 2011 Custom Dictionary File

Delete the outdated Office 2011 dictionary folder that Word is incorrectly trying to access when opening documents.

This issue typically occurs because the newer version of Word is still referencing a custom dictionary path configured during an older installation of Office 2011. Removing the referenced file forces Word to use the current default dictionary.

Quit Microsoft Word

Ensure that Microsoft Word and any other Office applications are completely closed before attempting to delete backend dictionary files.

Locate the Office 2011 Folder

Navigate through your Mac's Finder to locate the Microsoft Office 2011 folder that houses the old 'Custom Dictionary' file. This obscure file is usually found in your user library under Application Support or Preferences.

Move to Trash

Drag the Office 2011 folder containing the Custom Dictionary file into the Trash. Empty the Trash to permanently delete the conflicting file.

Alternative Settings Check: If the prompt continues after deleting the file, open Word, navigate to Preferences > Spelling & Grammar > Dictionaries, and verify which dictionary is selected as the default.

Frequently Asked Questions

Why does Word for Mac keep asking for a custom dictionary?

This happens when Word's settings are still pointing to a custom dictionary file from an older installation (like Office 2011) that has been moved, deleted, or corrupted over time.

Will deleting the old dictionary folder erase my current custom spellings?

If you added custom words specifically to that Office 2011 dictionary in the past, those specific words will be removed. However, your standard Mac dictionary and any new custom words saved in your current Word version will continue to function normally.

How do I change the default dictionary in Word for Mac?

Open Word and go to Word > Preferences > Spelling & Grammar. Click on the 'Dictionaries' button, select the dictionary you wish to use from the list, and ensure it is set as the default.
