Cách sử dụng
The expression "root and branch" refers to a complete and thorough process of examination, analysis, or eradication of something. It means to deal with something entirely, from its very beginning to its end. For example, if you say "we need to change the education system root and branch", it means the entire system needs to be examined and possibly rebuilt. This expression is often used in serious situations and discussions about whole changes, and not for small or insignificant matters.
