How do I add a new dictionary to my Kobo?

Author: Nicolas | Last update: April 18, 2023

Kobo e-readers are already provided with various dictionaries that allow you to get definitions of words in English, but also English translations from other languages.

Unfortunately, some of the dictionaries used are not sufficient for the taste of some Kobo users. We can often see these defects:

1. A lack of definition
2. A lack of freshness

If the role of Kobo (and other e-reader manufacturers) is first and foremost to provide a reliable material for displaying pages of text, it is true that this defect may bother some people.

Fortunately, there is now a solution! It is indeed possible to change the default dictionary and we will see how to add a new dictionary with many more definitions.

Download a new dictionary for Kobo e-reader

The first thing to do is to download this new dictionary.

For French, English, German, Spanish, Italian or Portuguese, I found this project which proposes a dictionary based on Wiktionary, a collaborative site close to Wikipedia: https://github.com/BoboTiG/ebook-reader-dict

We will download (in our case), the French dictionary at this address : https://github.com/BoboTiG/ebook-reader-dict/releases/tag/en (the file to download is called dicthtml-en.zip - you can download it here if the link does not work anymore)

I also found dictionaries for translations in this folder: https://download.wikdict.com/dictionaries/kobo/

Transfer your dictionary to the Kobo e-reader

Now you have to transfer the file to your Kobo e-reader. First of all, you have to connect it to a computer with the USB cable provided with the e-reader.

Then, you have to validate the file transfer on the screen of the Kobo e-reader. In your operating system, you should be able to see the e-reader using a file explorer (keyboard keys "Windows + e" in Windows).

You have to go to the files of your e-reader and find the ".kobo" folder. This folder is special and hidden, so you will need to set the folder view to show this type of file in Windows (or Mac).

All you have to do is copy the new downloaded file into the ".kobo/dict" folder of your Kobo e-reader to install the new dictionary.

Now that you've done that, you can disconnect your e-reader from your computer ("eject" in Windows or Mac) and restart your Kobo.

Setting up the e-reader to use the new dictionary

To use the new dictionary, you'll first need to make sure it's installed properly by going to your Kobo e-reader settings.

It should be called "English - English".

Then, you can use it directly from an ebook by underlining a word.

As we can see the result is much better with this dictionary!
