Choose "English" or "German." You will be given a sentence in that language.
Translate that sentence into the other language, and then click "Check."

Note: "Ihr" corresponds to "Y'all" in English. Sorry if I'm showing off my Southern roots
here too much, but otherwise there's no way to distinguish between singular and plural "you" in English.
Similarly, "Sie" in German is consistently translated as "they," though it could be formal, singular "you."
