We use ordinal numbers to express things like "number one" or "second," so mastering them in Chinese is important. Fortunately, they are also very easy to learn by just adding the prefix 第 (dì).

Basic Usage

In English, there are four different suffixes for ordinal numbers: -st, -nd, -rd and -th. Chinese makes things a lot simpler by using one prefix for all ordinal numbers: 第 (dì). This character is simply placed in front of the number:

Full Pattern with Measure Words

You can also add in a measure word and a noun to make the structure a bit fuller.

Structure

第 + Number + Measure Word + Noun

Examples

Note that there are some words that don't use measure words because they themselves are already measure words. For example: 天 (tiān), 年 (nián), 周 (zhōu), 次 (cì), etc.

Exceptions

Note that some nouns can form ordinals without 第 (dì). With these, the number can be used directly. For example, 七楼 (qī lóu) is "the seventh floor," even though there is no 第 (dì).
