Frequently Asked Questions
How do you spell it, 'chau' or 'chao'?
Both are correct! 'Chau' is the most common spelling in Argentina, Uruguay, and Peru, while 'chao' is more frequent in Spain, Chile, Colombia, and Mexico.
Is 'chau' rude?
Not at all, but it is informal. Use it with friends, family, and coworkers. In a very formal setting (like an interview), 'adiós' or 'que tenga un buen día' might be safer.
