二十

二十 (èr shí) means 'twenty' in English. It is a numeral used to represent the number 20, and it is commonly used in counting, dates, ages, and measurements.

The character 二 (èr) means 'two,' and 十 (shí) means 'ten.' Together, they form 二十, literally meaning 'two tens.' This structure follows the standard way of forming numbers in Chinese, where numbers are often constructed by combining smaller units.

二十 is widely used in daily life, such as in describing age (e.g., 二十岁 - twenty years old), quantities (e.g., 二十个苹果 - twenty apples), or time (e.g., 二十分钟 - twenty minutes). It also appears in idioms and expressions, like 二十不休 (twenty never stops), which can imply continuous action or persistence.
