What does it mean word for word?
The phrase không sao is composed of không, which means "no" or "not" and sao, which means "how" or "matter". Literally, it means "it doesn't matter how" or "it is no matter".
Which one should you use?
While không sao is a common way to say "it's okay" following an apology, không có gì is the more standard response used specifically for "you're welcome" after someone thanks you.
Is it said differently in some regions?
In Northern Vietnam, people often use không có gì in informal situations to convey the meaning of "no worries". In Southern Vietnam, speakers tend to use không sao đâu in informal settings.
How does it change in a sentence?
Adding the particle đâu to the end of the phrase to create không sao đâu emphasizes the negation. This makes the phrase sound more natural and reassuring during spoken conversation.
Did you know?
- The use of không as a negative particle grew in the 17th century as Western businessmen arrived in Vietnam and frequently used the number 'zero'.
