Notes on Usage

• "Mĩ kim" is a compound word formed from "Mĩ" (美, meaning America, from the Chinese-derived name for the United States) and "kim" (金, meaning gold or money). It literally translates to "American money."
• It is important to distinguish this term from "ngoại tệ" (foreign currency) or "tiền mặt" (cash), as "mĩ kim" refers specifically to the unit of currency.
