Characters
Chinese and Japanese are especially difficult languages because they use writing systems composed of thousands of different characters. If you're learning either of those languages, you can use this page to study the characters in all of your words. You can choose to answer with either the character itself, its pronunciation, or its meaning, and the page will prompt you with the other two pieces. Just like with conjugation, your characters are managed with the same four statuses, and you can view them on the Words page.
Now please have a look at the Case page.
