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.

This web application allows you to learn technical acronyms used in business, programming, education, and other fields. This type of application is very easy to replicate and could be used to display other types of information. Let me know if you would like me to code a similar application for another topic.
