Body Style
The Body Style editor allows you to control formatting options that affect the main content of your book.
Configuring the Body Style
With your Style selected, click the Configure button:

In the list of Style features, select Body:

Body Style Editor
The Body Style editor displays options for the text of each element:

The font family popup allows you to choose a font for your print edition. (In an ebook, the font is determined by the reader.)
Paragraph, justification, and hyphenation options apply to both ebook and print editions of your book.
Hyphenation
The Allow Hyphenation checkbox in the Body Style editor controls whether long words in your book can be split across two lines. Hyphenation is on by default, and is recommended, especially if Justify text is enabled.
Capitalized Words

Disabling Hyphenate capitalized words can be useful if, say, you don’t want character or location names to be hyphenated.

Disabling for Specific Words
You can also prevent hyphenation per word. For instance, you may not like where the word “vocabulary” is being hyphenated:

To prevent this word from being hyphenated, select it in Vellum’s Text Editor. Then right-click (or Control-click) on the selection to bring up the context menu and choose Disable Hyphenation:

When you’ve disabled hyphenation for a word, the Text Editor will display a blue underline underneath it.

Vellum’s Preview will also show you the updated layout after you’ve disabled hyphenation for a particular word.
