Troubleshoot spelling checks

Microsoft PowerPoint checks spelling as you type, and any words that aren't in the PowerPoint dictionary get marked with a red underline.

• To turn off automatic spelling checks, on the Tools menu, click Options, and then click the Spelling and Style tab. Clear the Check spelling as you type check box.
• To hide the underlines but keep automatic spelling checks on, on the Tools menu, click Options, click the Spelling and Style tab, keep the Check spelling as you type check box selected, and select the Hide all spelling errors check box.

Microsoft PowerPoint does not check the spelling in embedded objects such as charts, in special text effects such as WordArt, or in inserted objects such as Microsoft Word documents or tables.

It may be that the foreign words are not getting tagged with the correct language identification.

1. Select the foreign text. If the text is within an object such as a text box or AutoShape, select the object (or select multiple objects on a single slide).
2. On the Tools menu, click Language.
3. Select the language of the text you want checked for spelling, and then click OK.

   You may have to repeat these steps several times to mark text on several slides.

4. On the Standard toolbar, click Spelling .
