Usage of 倒数
The word 倒数 has two main uses in Mandarin. First, it refers to the mathematical concept of the reciprocal of a number, which is important in fractions and division. For example, the 倒数 of 2 is 1/2.
Second, 倒数 is commonly used to mean "countdown," especially in contexts like events or competitions where people count backwards to zero to mark the start or an important moment.
Common Collocations
- 倒数计时 (countdown timer): used in events or games to indicate time remaining.
- 新年倒数 (New Year's countdown): a popular phrase for the countdown to the new year.
- 倒数第三 (third from last): used to indicate position counting backwards.
Notes
When used as a noun for the reciprocal, 倒数 is often paired with numbers or fractions. When used as a verb or noun for countdown, it often appears with time expressions or events. Avoid confusing 倒数 (reciprocal) with 反数, which is less common but sometimes used in math. The countdown meaning is very common in daily life and media, especially around holidays or competitions.
