Notes on Usage
- In modern Vietnamese, "tỉ" (or "tỷ") exclusively means 1,000,000,000 (10^9). The older meaning of "milliard" is important for understanding historical texts or specific translations but is not used in contemporary everyday language.
- It is a numeral and is often used in contexts of finance, population, statistics, and large quantities.
- Do not confuse the standalone numeral "tỉ" with compound words that begin with "tỉ" such as "tỉ lệ" (rate) or "tỉ mỉ" (meticulous), which have distinct meanings.
