Third party dictionaries?

[Mr.Feras]

Hi!
I recently saw the post by enterio about some features on the kindle scribe and MTP, and he mentioned third party dictionaries, which I was not aware were possible with kindles.

so, can someone explain the method for this? I'm certain it involves converting to kfx, but is there a header or setting in calibre and the plugin to make the kindle think that this a dictionary instead of a normal book, for looking up words.

thanks.

[Enterio]

On my Kindle (Paperwhite, 11th gen), the dictionaries are held in the "\documents\dictionaries" subfolder (I kept my firmware to an older version to keep my USB connection).
When I bought them online (on Amazon, see Kindle Default Dictionaries category), I received pre-made MOBI files that I only had to place in the aforementioned subfolder, without converting them to other file formats.
Afterwards, I set up my default dictionaries for every language on my Kindle in Settings → Language & Dictionaries → Dictionaries.

Hope that helped.

[Mr.Feras]

Got it! thank you.

Kindle dictionary format is the original MOBI format, not KFX. They appear as .azw on the Kindle

I do not think you need to put them in /documents/dictionaries (anywhere in /documents should work), but it's probably convenient to keep them there.

This is a good article about where to find 3rd party dictionaries or how to create your own:

Thanks. I didn’t know it existed. I wonder if it’s possible to convert for Kindle this dictionary based on Wiktionary.

It should be possible, but interesting they do have not figured out how to make it available for Kindle there, given how comparatively popular Kindle is.

I think you could dump StarDict to XML and then it should be 'relatively easy' to migrate to mobi dictionary format.

I found this github project. Many languages. There are dictionaries for Kindle in mobi fomat. Haven't tested yet.

I tested it on my Paperwhite. Was not working...

You might file an issue on GitHub. Whatever I downloaded is not .mobi format as far as I can tell (calibre could not convert it, KindleUnpack could not unpack it).

For me, KindleUnpack started to unpack it before calibre gave the following error message:

OTOH, I seem to remember it being mentioned that the Mobi dictionary format was not the same as the standard mobi format.

Edit: Just for the heck of it, I copied the English-English Wiktionary file into /documents/dictionaries on my Paperwhite 10th gen. It showed up when I displayed English dictionaries and I was able to select it. A word lookup from within a book worked. All in all, I would say the dictionary does work on a Kindle.

As far as I can see, this Wiktionary doesn't seem to include the etymology of the word like the one made for Kobo.

Well, it is standard mobi, and there was a specification for it on Mobipocket.com (probably still kicking around on Archive.org?). It has not changed as far as I know.

Seems there may be encoding issue?

Seems as if it works on my Paperwhite 10th gen.

When I unpacked it and then unpacked the kindlegensrc.zip file, it seemed to match what I saw in Creating Dictionaries which has several differences from a standard mobi.

The log file indicated it was created by KindleGen 2.9 under Windows with several warnings.
