The Vietnamese word "sất" is a particle used for emphasis. It is often used to stress that there is absolutely "nothing" or "not at all" of something. This word can help to emphasize the extent or degree of a negative situation.
Chẳng có gì sất.
(There is nothing at all.)
This sentence stresses that there is absolutely nothing present.
Mình không thấy ai sất cả.
(I don't see anyone at all.)
Here, "sất" emphasizes that there are truly no people visible.
While "sất" itself does not have direct variants, you may encounter similar emphasis particles like "chẳng" or "không" in negative constructions. However, "sất" is specifically focused on emphasizing the absence of something.
The primary meaning of "sất" revolves around emphasis on negation. It does not have multiple meanings; its role is consistent in emphasizing that something is completely absent.
"Sất" is a useful word to know when you want to emphasize that there is nothing or not at all about something in Vietnamese.
