I encountered a very useful dictionary eight years ago, but have never been able to find a copy of it because I don't know what it's called. It not only gave examples in context of how to use the words, but also gave examples of how NOT to use the word (marked with an 【误】, if I remember correctly). Can anyone identify a dictionary that has this feature?
I recommend this《小學生的國語辭典》approved by the Taiwanese Ministry of Education for their primary school students. It contains the following features:
语文帮手 (or language assistant) to highlight certain words that require particular attention. For example:
小提醒 (or small reminders) for listing synonyms (相似詞), antonyms (相反詞) and active terms (活用詞). For example:
追本溯源 (or trace the origin) to explain the historical background that give rise to the word. For example:
Note that the dictionary is written in traditional Chinese (繁体字) and that it is availabe on Google Books.
