So far as I know, nothing is told about the word class (adjective, verb, noun, ...) in the study panel. I saw on the FAQ that it's almost impossible for all the 100 000 definitions. Why not then focus on the most common characters and words ? It would be an interesting feature, especially for new words, and those who have many classes, such as 打算 （both noun and verb).

While submitting word corrections, we could tick some cases, such as :

- verb（动词）
- noun (名词）
- adjective （形容词）
- adverb（副词）
- classifier (量词）
- preposition (介词）
- conjunction (连词）
- ...
