How can you tell the difference between

How can you tell the difference between "deputy"and "vice"? And how to use them with some words such as: director, manager, chief, minister, president and so on...

Tớ chỉ biết mỗi 1 cái difference thui nhưng cũng chưa dám chắc 100%, đó là dù cùng là "phó" nhưng các bác phó Deputy thường đc ủy nhiệm công việc của bác trưởng khi bác ý vắng mặt or TH đặc biệt ..., còn bác phó Vice thì không thể thế chỗ bác trưởng tạm thời đc, các bác ý thường đứng đầu một chức năng cụ thể ( cái nì thg thấy trong các công ty , VPs í)

"vice" tends to mean "next in command," and applies to a relatively small number of individuals, such as vice-presidents of a corporation, but "deputy" can apply to a large number of people.
For example, the "sheriff" is the chief law-enforcement officer in an American country and can have hundreds or perhaps more than a thousand deputies (deputy sheriffs).

So does ''deputy" some times: deputy manager, deputy chairman

Really?

Nope, that''s a lie! Funny girl

Vice là phó . Còn deputy là phó thường trực .
For instant :
Mr Nguyễn Sinh Hùng : deputy
Mr Hoàng Trung Hải : vice

that''s not the way ......

Cái này copy từ google nhé:
Essentially there is no difference in meaning, they both refer to the same position relative to the top position. Yet, there is a difference how we customarily use them.
For example, we say, "She is the vice-principal of the school," but not, "She is the deputy principal of the school. Why? I don''t know -- that is just the way we say it. Also, we don''t say, "He is the vice-sheriff of the county," but rather we say, "He is the deputy sheriff of the county." Again, the difference is not in meaning, but in convention.
In the use of these words, this is where one must following the old adage, "when in Rome, do as the Romans do."
