Loading and Using Custom Dictionaries in PowerPoint 2013 for Windows

You may wonder what happens behind the scenes when you run a spell check in PowerPoint or any other Microsoft Office program. This is what happens:

1. PowerPoint looks at each word you have typed and matches those words with the entries listed within its dictionary.
2. If it comes across any word that the dictionary does not contain, it goes ahead and marks that word as misspelled.
3. Then it offers you suggestions for that supposedly misspelled word, so that you can replace that word with any other similar word found within its dictionary.

So why did we use the term "supposedly" in the last sentence? That's because PowerPoint's dictionary is quite basic, and includes mainly words used in common, everyday language. If a word does not exist within that dictionary, it is not necessarily misspelled! There are so many specialized words in different knowledge branches like medicine, research, law, computing, etc. that are not common words. Yet, they are perfectly valid as far as spellings are concerned.

To counter this state of affairs, you can buy several specialized dictionaries. In fact, some great dictionaries are also available free of cost. These dictionaries can be then loaded within PowerPoint and other Microsoft Office programs to give you a larger range of words to use.

Follow these steps to load a dictionary within PowerPoint 2013 for Windows:

1. Launch PowerPoint 2013, and choose File | Options, as shown in Figure 1.

3. Now, click the Custom Dictionaries button (highlighted in red within Figure 2, above). This summons the Custom Dictionaries dialog box (see Figure 3). Note that there will be at least one dictionary named RoamingCUSTOM.dic (highlighted in red within Figure 3) This is typically the default custom dictionary to which you manually add new spellings.

8. Once done, click the OK button within the Custom Dictionaries dialog box to save any changes you made.
9. Now that we loaded a medical dictionary, PowerPoint no longer puts red, squiggly lines under words such as Abdominoplasty (see Figure 7 below). However, Propria Persona is still showing up as misspelled. You need to get a legal dictionary next!
