Questions & Answers about Tôi mong cậu ổn.
A word-by-word breakdown is:
- Tôi = I
- mong = hope / wish
- cậu = you (used for a familiar person, often around your age, depending on relationship)
- ổn = okay / fine / all right
So the sentence means something like I hope you’re okay or I hope you’re doing okay.
Vietnamese often does not use a verb like to be in the same way English does.
In English, you say:
- you are okay
In Vietnamese, it is very common to just say:
- cậu ổn = you okay / you’re okay
So ổn works like a predicate adjective here, and no separate word for are is needed.
