How to Add and Use Custom Dictionaries in Microsoft Word

Word includes a custom dictionary in addition to the default main dictionary. There are a few ways you can add words to Word’s custom dictionary. We’ll show you how.

Word includes a custom dictionary in addition to the default main dictionary. You can add words to Word’s custom dictionary as you do a spell check or using the context menu.

If you have a lot of words you want to add to Word’s custom dictionary, you can manually edit the custom dictionary. You can also add third-party dictionaries with specialized words, like medical and legal dictionaries. Today we’ll show you how to manually edit the custom dictionary, create a new custom dictionary, and add third-party dictionaries.

Where are Word’s Custom Dictionaries?

To access the custom dictionaries in Word, click the File tab. Then, click Options.

Go to File.> Options in Word

On the Word Options dialog, click Proofing on the left. Then, scroll down on the right and click Custom Dictionaries in the When correcting spelling in Microsoft Office programs section.

Click Custom Dictionaries in Word settings

All available custom dictionaries are listed on the Custom Dictionaries dialog. You can deactivate a dictionary by clearing the check box to the left of that dictionary.

Add a Third-Party Custom Dictionary

If you write special types of documents, like medical or legal documents, you can add a third-party dictionary to Word. This allows you to quickly and easily add many specialty words to Word for use when checking spelling.

To add a third-party dictionary, open the Custom Dictionaries dialog. For our example, we’re going to add the Raj&Co free medical dictionary.

A custom dictionary must be selected to be able to add a custom dictionary. Select any of the dictionaries in the list and then click Add.

Click Add on Custom Dictionaries dialog in Word

On the Add Custom Dictionary dialog, navigate to the location of the third-party custom dictionary you want to add. Then, select the .dic file and click Open.

Select a custom dictionary to add in Word

The added dictionary displays in the Dictionary List. Click OK.

Close Custom Dictionaries dialog in Word

Add a New Additional Custom Dictionary

As we’ve shown, you can have multiple custom dictionaries that Word uses when checking spelling. In addition to third-party dictionaries, you may want to split up your own custom dictionaries. For example, maybe you want one dictionary for personal use and one for work.

To create a new custom dictionary, open the Custom Dictionaries dialog, and then click New.

Click New on Custom Dictionaries dialog in Word

The location for the custom dictionaries is C:\Users\<username>\AppData\Roaming\Microsoft\UProof (change “<user name>” to your Windows user name) by default and this directory is selected on the Create Custom Dictionary dialog box. Enter a name for your new custom dictionary in the File name edit box and click Save.

NOTE: You must keep the .dic extension on the file name.

Create Custom Dictionary dialog in Word

Add words to your new dictionary as you did when manually adding words to an existing dictionary. Click Edit Word List, add your words, and then click OK on both dialogs.

Remove a Custom Dictionary

If you ‘re not using a custom dictionary anymore, you can remove it from Word.

Open the Custom Dictionaries dialog, select the dictionary you want to remove, and then click Remove.

NOTE: The .dic file is NOT removed from your hard drive, only from the list of custom dictionaries in Word.

Change the Language Associated with a Custom Dictionary

When you add or create a new custom dictionary, Word associates all languages with that dictionary, which means the dictionary is used to check spelling in any language. If you want to associate a specific language with a custom dictionary, you can choose the language for that dictionary. Word will then use that dictionary when you spell check a document written in that language.

To change the language associated with a custom dictionary, open the Custom Dictionaries dialog. Select the dictionary for which you want to change the language in the Dictionary List and then select the language you want from the Dictionary language drop-down list.

Click OK on the Custom Dictionaries dialog and then again on the Word Options dialog.

Back Up Your Custom Dictionaries

It’s a good idea to back up your custom dictionaries in case you need to transfer them to another computer or copy them back to the same computer if you need to reinstall Office.

Copy the files in the C:\Users\<user name>\AppData\Roaming\Microsoft\Uproof (change “<user name>” to your Windows user name) directory to another drive. Then, you can simply copy these files back to the same directory (or equivalent user directory) to restore them.
