If your text is automatically hyphenated and certain hyphenated words look ugly, or if you want specific words never to be hyphenated you can switch off hyphenation for those words:
Choose Tools - Options - Language Settings - Writing Aids
Select a dictionary in the User-defined dictionary list, and then click Edit.
If the list is empty, click New to create a dictionary.
In the Word box, type the word you want to exclude from hyphenation, followed by an equal sign (=), for example, "pretentious=".
Click New, and then click Close.
To quickly exclude a word from hyphenation, select the word, choose Format - Character, click the Font tab, and select "None" in the Language box.
Some words contain special characters that Office treats as a hyphen. If you do not want such words to be hyphenated, you can insert a special code that prevents hyphenation at the position where the special code is inserted. Proceed as follows:
Position the cursor at the place where no hyphenation should occur.
Choose Insert - Formatting Mark - Word Joiner.
The inserted formatting mark will be shown in gray. To remove it, simply place the cursor over the formatting mark and press the Del
key.
