To prevent Microsoft Word from questioning the spelling of words that aren't in the main dictionary, you can use a custom dictionary. Word shares custom dictionaries with other Microsoft programs, such as Microsoft Outlook.
Create a new custom dictionary
Custom dictionaries of different languages are grouped by language in the Dictionary list box.
How?
Add an existing custom dictionary
The Custom Dictionaries dialog box lists the available custom dictionaries Word can use to check spelling. If the dictionary you want to use ù for example, one you purchased from a third-party company ù is installed on your computer but not listed in the Dictionary list box, you can add it.
If you need help installing a third-party dictionary, see the installation instructions for that dictionary.
In Microsoft Windows
2000 or later
Custom dictionaries are stored by default in the C:\Program Files\Common Files\Microsoft Shared\Proof folder.
In Microsoft Windows Millennium Edition or Microsoft Windows 98
Custom dictionaries are stored by default in either the C:\Windows_folder\Application Data\Microsoft\Proof folder or the C:\Windows_folder\Profiles\User_name\Application Data\Microsoft\Proof folder.
In Microsoft Windows NT 4.0
Custom dictionaries are stored by default in the C:\Windows_folder\Profiles\User_name\Application Data\Microsoft\Proof folder.
The custom dictionary appears in the list of dictionaries in the Custom Dictionaries dialog box.
If you want to make this dictionary the default dictionary, click the dictionary name, and then click Change Default.
How?
Add, delete, or edit words in a custom dictionary
Add words to a custom dictionary during a spelling check
If you don't see your custom dictionary in the list, you need to activate the dictionary.
Tip
If you're using automatic spell checking, here's an even faster way to add a word to a custom dictionary: Right-click a word with a wavy red underline, and then click Add to Dictionary on the shortcut menu.
Change the language associated with a custom dictionary
Click Custom Dictionaries.
In the Dictionary list box, click the dictionary you want.
Click Modify.
In the Language box, click the language you want for the dictionary.
Change the default custom dictionary
You can change the custom dictionary that Word uses by default to check spelling, either for all languages or for a particular language.
On the Tools menu, click Options, and then click the Spelling & Grammar tab.
Click Custom Dictionaries.
In the Dictionary list box, select the dictionary you want.
If the Dictionary list box contains any dictionaries that are associated with a particular language, then dictionary names appear under the appropriate language heading, or under All languages.
To change the default dictionary for all languages, click the dictionary name under All languages.
To change the default dictionary for a particular language, click the dictionary name under the language heading.
Click Change Default.
The next time you check spelling, Word uses the default custom dictionary you selected.
Note Each dictionary language grouping, including All languages, has a default custom dictionary.
