goodbye

The word "tạm biệt" is the most standard way to say goodbye in Vietnamese. It carries a sense of "see you later" or "until we meet again," derived from the root meaning of a temporary separation rather than a final departure. While "tạm biệt" is widely understood, it can sound a bit formal or literary in very close relationships. Friends often prefer context-specific leave-takings like "chào nhé" or "gặp lại sau," whereas "tạm biệt" is safe and polite in almost any professional or semi-formal social setting.
