Edit Custom Dictionaries in PowerPoint 2010 for Windows

Learn how to edit custom dictionaries in PowerPoint 2010 for Windows. You can add, alter, and remove words.

Imagine this scenario: you have created a specialized, medical presentation that's full of squiggly, red, underlined words! These squiggly underlines indicate what PowerPoint considers to be as a misspelled word! Don't blame PowerPoint, because its medical skills are somewhat limited. We do know that almost all the words in your medical presentation are perfectly valid as far as spelling is concerned. The silver lining here though is that you can teach PowerPoint to spell those words, and enhance PowerPoint's custom dictionary.

Of course, not only can you teach PowerPoint how to spell medical words, but you can also teach the program how to spell words that enhance lexicons in various other subjects such as research, law, computing, etc. Any changes you make by adding new spellings of words in PowerPoint will also influence spell checking in other Microsoft Office programs such as Word, Excel, or Outlook because they all share the same dictionaries.

Typically, when you encounter a word indicated as misspelled, you can right-click to bring the contextual menu that you see in Figure 1, and then select the Add to Dictionary option. This action adds a new word to PowerPoint's custom dictionary.

  • Alternatively, you can use the Add button from within the Spelling dialog box. Either way, this word is added to your custom dictionary. A custom dictionary is essentially a list of words that is different from PowerPoint's regular, built-in dictionary. Typically, PowerPoint refers to both its built-in and custom dictionaries to ascertain if any word is misspelled.

    Here is a typical side-effect of adding new words to your custom dictionary: you may click the Add to Dictionary option sometimes due to your cursor slipping, or just by mistake. Yes, you can remove that misspelled word from the dictionary, and also add new words to the dictionary by editing your Custom Dictionary:

    1. Launch PowerPoint 2010 for Windows if it is not already open, and choose File |Options, as shown in Figure 2.

    2. Figure 2: Choose Options within the File menu
    3. This opens the PowerPoint Options dialog box. Click the Proofing option in the sidebar to view the interface that you see in Figure 3, below.

    5. Tip: If you are already doing a spell check, just click the Options button within the Spelling dialog box. This gets you to the Proofing section of the PowerPoint Options dialog box, as shown above in Figure 3. Want to know more about the Spelling dialog box?

    6. Click the Custom Dictionaries button (highlighted in red in Figure 3, above). This summons the Custom Dictionaries dialog box (see Figure 4). Note that there is only one dictionary at this point of time named CUSTOM.DIC (highlighted in red in Figure 4). However it is entirely possible to have more than one custom dictionary.

    8. To edit the words within the selected CUSTOM.DIC dictionary (or any other dictionary), select it and click the Edit Word List button, as shown highlighted in blue in Figure 4, above.
    9. This opens the CUSTOM.DIC dialog box with a list of the words in the dictionary, as shown in Figure 5.

    11. Note that the Add button in the dialog box (highlighted in red in Figure 5) is grayed out.
    12. Note: In Figure 4 above, you can see that the dialog box is named CUSTOM.DIC. The name of this dialog box differs based upon the dictionary you have selected within the Custom Dictionaries dialog box. In this case, we had selected the CUSTOM.DIC, hence the name. If you have selected other dictionary, the dialog box will read the name of the other selected dictionary.
    13. To add a word within this dictionary, type the word within the Word(s) text box (highlighted in red in Figure 6). Note that as soon as a new word is typed, the Add button (highlighted in blue in Figure 6) is activated. Click the Add button to include this new word within your custom dictionary.

    14. Figure 6: Enter a new word within the Word(s) text box to add it to the dictionary
    15. To delete any existing word, just select it (refer to Figure 7), and click the Delete button (highlighted in red in Figure 7).

    16. Figure 7: Word selected for deletion
    17. Once done, click the OK button within the CUSTOM.DIC dialog box. This will take you back to Custom Dictionaries dialog box, where you click the OK button to save any changes you made.
    18. Save your presentation often.
