Insert a Hyphen
Source: Microsoft Tips
If a word is too long to fit at the end of a line, Microsoft Office Word 2007 moves the word to the beginning of the next line instead of hyphenating it. However, one can use the Hyphenation feature to automatically or manually hyphenate the text, insert optional or nonbreaking hyphens, and set the maximum amount of space allowed between a word and the right margin without hyphenating the word. When one uses automatic hyphenation, Office Word 2007 automatically inserts hyphens where they are needed. When one uses manual hyphenation, Word searches for the text to hyphenate and asks the user whether he or she wants to insert the hyphens in the text.
