十一

十一 (shí yī) is the Chinese numeral for 'eleven', used to represent the number 11 in both written and spoken contexts. It is distinct from other numbers like 十 (shí, ten) and 一 (yī, one), combining them to form the value eleven.

The character 十 means 'ten', and 一 means 'one'. Together, they literally translate to 'ten plus one', which directly corresponds to the number eleven. This structure is common in Chinese numerals, where numbers are often constructed by adding smaller units together.

十一 is commonly used in dates, such as November 11th (十一月十一日), and in contexts like the Chinese Singles' Day (光棍节, guānggun jié), which falls on November 11th. It is also used in everyday counting and in formal writing to denote the number 11.
