How it's used

This prefix is primarily used in formal or literary contexts to denote the second in a sequence or rank. It is rarely used in casual daily speech, where people prefer using numbers like 第二個 or 老二 to describe the second person or thing. You will mostly encounter it in titles, historical records, or formal descriptions of family hierarchy.

Examples

He is my second son, he is studying at university this year.

Common phrases

second son
second seat or position

Common mistake

Learners often mistakenly use this as a standalone word for 'next' or 'second time', but it functions strictly as a prefix in this sense. For 'next time' or 'second time', use 下次 or 第二次 instead.
