Besides the built in dictionaries, here I've also collected many useful custom dictionaries. If you are interested in installing kobo customer dictionaries, choose one from the below list:

Chamber's Twentieth Century Dictionary of the English Language (London) 1908>> Chambers1908.zip

Webster's Unabridged Dictionary (US) 1913 Websters1913.zip

Thanks to the MobileRead Forum contributors, here is the complete list of the Kobo custom dictionaries they've contributed.

Kobo Dictionary Install

After downloading the kobo dictionaries, it is your turn to install them on your Kobo eReader.

Step 1 Connect your kobo to your computer.

Step 2 On the Kobo go to the ".kobo\dict" folder, and rename "dicthtml.zip" to "dicthtml.backup.zip". This backs up your existing English dictionary (which I assume you already have installed).

copy and paste kobo dictionary

Step 3 Download any of the Kobo custom dictionaries mentioned above to get the dicthtml.zip file. Then copy and paste it to ".kobo\dict" folder on the reader.


  • 1. Don't unzip the dicthtml.zip file.
  • 2. In order to get your Kobo device to recognize the dictionary files, you have to use it to replace an existing original dictionary. To do this, you have to use the file name of an existing original dictionary. If you don't do so, the dictionary name would be messy code like the following picture.

Step 4 Eject your kobo from computer.

Step 5 Open any book, press and hold the word to display the definite of this word.

To change the dictionary, just tap the arrow beside the dictionary to display more installed dictionaries. Now just tap it to change your default dictionary.
