Use a custom dictionary in Office for Mac

When you use the spelling checker, it compares the words in your document with those in the main dictionary. The main dictionary contains the most common words, but it might not include proper names, technical terms, or acronyms. In addition, some words might be capitalized differently in the main dictionary than in your file. Adding such words or capitalization to a custom dictionary prevents the spelling checker from flagging them as mistakes. You can create additional custom dictionaries to complement the default dictionary that is included with the Office for Mac applications.

Add a word from your document to a custom dictionary

1. In the document, select the word that you want to add.

2. On the Tools menu, click Spelling and Grammar.

   Note: The Spelling and Grammar dialog box won't open if no spelling or grammar errors are detected, or if the word you are trying to add already exists in the dictionary.

3. In the Add words to menu, select the dictionary you want to add your word to.

4. Click Add.

Create a new custom dictionary in Word

You can save a new custom dictionary in any location on your computer. Or, to give other users access to your dictionary, you can save it to a network folder

Import a custom dictionary in Word

The Custom Dictionaries dialog box in Word lists the available custom dictionaries the application can use to check spelling. If the dictionary that you want to use — for example, one that you purchased from a third-party company — is installed on your computer but not listed in the Dictionary list box, you can add it.

Change the language that is associated with a custom dictionary

By default, when you create a new custom dictionary, the application sets the dictionary to All Languages, which means that the dictionary is used when you check the spelling of text in any language. However, you can associate a custom dictionary with a particular language so that the application uses the dictionary only when you check the spelling of text in a particular language.

1. Make sure that a document is open.

   If no document is open, the next step won't work.

2. On the Word menu, click Preferences.

3. Under Authoring and Proofing Tools, click Spelling and Grammar.
