Creating a Custom Dictionary for Microsoft Word

As a sci-fi and fantasy writer, I do a lot of world building. I create new words for fictional creatures, places, and concepts. I keep track of them to ensure I’m using them consistently. And I appreciate when the software I’m writing in can help with that, at least in terms of spelling. You probably know that Microsoft Word has a built-in spell checker. You may know you can choose to have the program ignore a particular error or add words to the dictionary when prompted. But did you know that you can create a custom dictionary for each of your fictional worlds and swap them in and out whenever you’d like?

To do this, all you need is a list of your desired words and a program that can create text documents. I recommend Notepad, which came free with my computer and more than likely is on yours as well if you have Windows. On my computer, it can be found under Windows Accessories. Otherwise, I can find it by typing Notepad into the search bar at the bottom of my desktop.

From here, all you need to do is add one word per line, select Save As, and save it with a .dic at the end of the file name and an Encoding of UTF-16 LE. Make sure you’ve changed the “Save as type” to All Files.

Now, in Microsoft Word, go to File and select Options. On the left side, there’s an option called Proofing. Click on it to see a button for Custom Dictionaries. From here you can click Add and select your custom dictionary to have it added to the list.

The windows shown when adding a custom dictionary in Microsoft Word

Any time you want to use your spell checker on a document unrelated to your novel or you want to use a different custom dictionary on a second novel, you can come back and use the remove button. Simple as that!

Once added, you can also use the Edit Word List button to add or remove words without having to open the dictionary file separately. From this same window, you can even add autocorrects for custom words if you’d like them. If there’s one in particular you’re always misspelling, you can pop it right in and Word will fix it for you after you type it incorrectly.

Personally, I find that every little thing like this cuts back on my annoyances substantially. Every time I don’t get a little red line under the name of my fictional country is a time my focus doesn’t get interrupted, and every error the spell checker can catch for me is one less thing to worry about when preparing my final draft to be sent out. I really value putting in a little time upfront to prevent headaches in the long run. If you’re a user of Microsoft Word, feel free to try it out and see if it works for you.
