This web application allows German users and Dutch users to transfer their knowledge of their language’s morphology to the other language. By separating words into morphemes, it allows users to learn spelling and grammar in small steps.
The application is bi-directional, meaning that users can either practice writing in German or in Dutch. There is also the “easy” mode option, which only asks for affixes instead of word roots.
