You can specify the language to be used for hyphenation and spell checking by applying a character language to text. This lets you mix words from different languages in the same paragraph without triggering poor hyphenation or more Suspect Words in Spell Check (Utilities menu). In addition to applying a specific language to characters, you can apply None so that a word is not considered for hyphenation or spell checking.

To apply a language to selected characters, use the Language drop-down menu in the Character Attributes dialog box (Style > Character) or the Character tab of the Measurements palette.
