Meaning

第二 is the ordinal number meaning 'second' in position, rank, or sequence. The prefix 第 transforms cardinal numbers into ordinal numbers in Mandarin. It's one of the most basic and frequently used ordinal numbers in Chinese.

Usage

Used in formal and informal contexts to indicate order or rank. Can function as an adverb meaning 'secondly' when listing points. Unlike English, 第二 typically comes before the noun it modifies (第二个人 'the second person'). Very common in everyday speech, writing, and academic contexts.
