Wordreference is the best online dictionary out there, it's free and works very well with multiple languages. Recently I saw this post on their forum [dictionary for kindle devices ](https://forum.wordreference.com/threads/dictionary-for-kindle-device.2037145/), and its an old post (2011). The idea was to "compile" wordreference - let's say english - dictionary into a .mobi file and put it in kindle so you could use it offline as your kindle dictionary. Does anyone know how to do that? Or is there already a solution to this out there? It would be amazing to use wordreference offline on kindle as a tool to learn other languages.
