I want to get the best possible dictionary for KOReader. Does anyone have the Oxford English Dictionary in a way that is usable by KOReader? Or does anyone know of a similar dictionary?
What about dictionaries in other languages? Any way to convert Kobo dictionaries to KOReader dictionaries?


Best English dictionary in my opinion is Oxford Dictionary of English. This is default dictionary for Kobo ereader. I don’t know a lot about KOReader, but it seems it uses Stardict dictionary. I uploaded my own stardict convertion of ODoE on my brench(“Stardict_-_Oxford_Dictionary_of_English.zip” you need to unzip it). I hope it works (it should): https://gitlab.com/grilj.anze/e-reader-dictionaries-kobo-txt/-/tree/d83d17d2d006a13f0b406a6065cb04ae729d6153/
Thank you!
Can you also do this with other languages? The PT-PT (Portuguese, from Portugal) dictionary on Kobo is quite ok. I would love to have it available on KOReader.
I’ll take a look when I have the time.
Thank you, that would be great!
I uploaded stardict PT-PT. You can check it out, if it works. It should be the same dictionary as KOBOs, with similar formatting. If there are big problems, I can try to improve it.
Thank you!
I will try it out later and see how it goes. Did you take this from Kobo itself? It would be nice to learn how to do that!
No, I just check what version they are using and download the same one. I tried directly from Kobo, but you can only extract “words,” not definitions; those are encoded.
I then use pyglossary to convert to something editable like txt. Then i use python scripts (made by chatgpt) to improve formatting. Or sometimes I manually do some. It all depends how much time i want to spend on them. I spend enourmous amount on english so its kinda perfect
I also make a bunch of dictionaries merged into one. So i can see in one dictionary definition in english and translation in my native language. And i also add fictionaries for books i am reading (names, locations etc). I scrape or download from fandom wiki. But yeah all of this i make with the help of python scripts and chatgpt otherwise I wouldn’t know how to.
I am not sure if you are aware, but there is a “fandom wiki” dictionary maker: https://github.com/Runik-3/core. I have used it in the past and it works perfectly.
