Đâu là sự khác biệt giữa hiểu sai và hiểu lầm và hiểu nhầm ?Hãy thoải mái đưa ra các câu ví dụ nhé.

Hi Eriinye!
I'm glad that My anwser is a frist.

All of them are almost the same meaning.
You just use it, we can get it. It's ok, no matter!
But they are little different:
Hiểu sai- it usually use for something, knowledge. Sometimes it use for human and it usually apparente in the test, books, news
Hiểu lầm- 100% it use for human. When someone try to explain that they are not like that (bad way, bad person or be wrong something )
Hiểu nhầm- this word is not common in the south Việt Nam. Ah ok, this word usually use in situations for example: you say something& mean something but i got something else, and that moment you said: bạn hiểu nhầm tui gòy, ý tui là vậy nè!
