SoYouLearn is a general learn platform which you can use to study geography, history or languages.
For language learning, however, there are some specific features:
All language categories already define an *official* schema that allows you to define vocabulary. Note that many translations have already been defined by us but you can also use that schema to define your own.
For learning languages it is essential to not only learn the words but also how they might actually be used in real world sentences. For this purpose each flash card can be connected to multiple example sentences where the word is used. After each review a random example sentence is displayed to you. This helps you in actually learning the language and not just the vocabulary.
