Frequently Asked Questions
Where is the default custom dictionary stored on a Mac?
By default, Microsoft Word for Mac stores its local custom dictionary deep in the library folder, specifically at `~/Library/Group Containers/UBF8T346G9.Office/Custom Dictionary`.
Can I share a custom Word dictionary between a Windows PC and a Mac?
Yes. Custom dictionaries are simple plain text files with a .dic extension. You can store this file in a cloud syncing service like OneDrive or Dropbox, and add it manually to the dictionary preferences in Word on both Windows and macOS.
Why is my custom dictionary grayed out when I try to add it?
The file might be saved in a read-only location or lacks the proper format. Ensure the dictionary file has read and write permissions on your current Mac and is formatted as a plain text file with a .dic extension.
