The Vietnamese word "hoa kỳ" refers to "America" or "the United States." It is commonly used to describe anything related to the United States, including its people, culture, and geography.
"Tôi muốn du lịch đến Hoa Kỳ."
(I want to travel to America.)
"Người Hoa Kỳ rất thân thiện."
(Americans are very friendly.)
In more advanced contexts, "hoa kỳ" can be used in discussions about international relations, culture, or economics when comparing Vietnam and the United States.
While "hoa kỳ" primarily means "America" or "the United States," in a more poetic or historical context, it can also refer to concepts of freedom and democracy associated with the U.S.
