which, that ) hay các trạng từ quan hệ như (where, when, why). Mệnh đề quan hệ đứng ngay đằng sau danh từ, đại
từ trong mệnh đề chính để bổ sung ý nghĩa cho danh từ, đại từ ấy,phân biệt danh từ đại từ ấy với các danh từ đại từ
khác. Chức năng của nó giống như một tính từ do vậy nó còn được gọi là mệnh đề tính ngữ.

2.Mệnh đề quan hệ không xác định (non- restrictive relative clause )
-Mệnh đề quan hệ không xác định dùng để bổ nghĩa cho danh từ đứng trước,là phần giải thích thêm, nếu bỏ đi
mệnh đề chính vẫn còn nghĩa rõ ràng.
-Mệnh đề quan hệ không xác định thường được ngăn với mệnh đề chính bởi các dấu phẩy. Danh từ đứng trước
thường là tên riêng hoặc trước các danh từ thường có các từ như: this, that, these, those, my, his her…đứng
trước.
