Manage user dictionaries

Last updated on Jun 2, 2026

Learn how to create, add, and organize custom dictionaries across Adobe InDesign documents.

User dictionaries store custom words for spell-checking and apply across all InDesign documents. You can create dictionaries or add them from previous InDesign or InCopy versions, shared files, or a workgroup server. Dictionary management affects all InDesign documents, not just the currently open file.

Select Edit > Preferences > Dictionary (Windows) or InDesign > Preferences > Dictionary (macOS).

Select the language you want to manage from the Language drop-down menu.

Choose an option:

  • Relink User Dictionary icon: Locate and open a user dictionary if you view a question mark next to it.
  • New User Dictionary icon: Create a new dictionary. Set the name and location of the user dictionary (which includes a .udc extension), then select Save.
  • Add User Dictionary icon: Add an existing dictionary. Select the user dictionary file, which includes a .udc or .not extension, select Open.
  • Remove User Dictionary icon: Remove a dictionary from the list. 
    The dictionary is added to the list under the Language drop-down menu. You can add or remove words from dictionaries when checking spelling or by using the User Dictionary dialog box.
