Using Automatic Hyphenation in Word 2008 for Mac
Word 2008 for Mac includes an extensive hyphenation dictionary, which you can use manually (the default) or automatically. You’ll probably use the automatic hyphenation unless you’re extremely picky about hyphens.
To hyphenate an entire document manually, choose Tools→Hyphenation and then click the Manual button at the bottom of the Hyphenation window. To hyphenate part of a document, select the part you want to hyphenate, choose Tools→Hyphenation, and then click the Manual button at the bottom of the Hyphenation window. Either way, you see the Manual Hyphenation dialog. This dialog shows you the proposed hyphenation for each word, and you can accept it by clicking Yes or reject it by clicking No.
To turn on automatic hyphenation, choose Tools→Hyphenation and select the Automatically Hyphenate Document check box. Word then automatically hyphenates words that require hyphenation without displaying the dialog.
