Các mệnh đề đi sau Until, After, Before, When là những mệnh đề phụ. Chúng phải được đi kèm với mệnh đề chính thì câu mới rõ cấu trúc cú pháp.
- Có thể đảo trật tự của từng mệnh đề trong câu với điều kiện là nếu mệnh đề when, after, before, until đi trước thì phải có dấu phẩy trước mệnh đề chính.
VD: I'll stop explaining to you about this until you can master
= Until you can master, i'll stop explaining this to you.
(Tôi sẽ thôi... khi bạn nắm được vấn đề)
