không
[xəwŋ͡m˧˧]
The English word "not" is translated into Vietnamese as không.
không is the most common word used for negation in Vietnamese, serving to deny that something is true or to express negation in a sentence.
Which one should you use?
While không is the standard way to negate a state or an action, you may encounter chẳng, which is a more emphatic or colloquial way to say "not" used in literary contexts or certain dialects.
How does it change in a sentence?
In simple sentences using adjectives, place không directly before the adjective to negate it. To express that something does not exist or that one does not possess something, use the phrase không có.
Did you know?
- The rise of không as the primary way to say 'not' is linked to the arrival of Western businessmen in the 17th century. This was because the concept of 'zero' was frequently used in trade contexts.
