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:

Structure

第 + Number

Examples

Chinese English
第 一dì-yīThe first
第 二dì-èrThe second
第 三dì-sānThe third
第 四dì-sìThe fourth
第 五dì-wǔThe fifth
第 六dì-liùThe sixth
第 七dì-qīThe seventh
第 八dì-bāThe eighth
第 九dì-jiǔThe ninth
第 十dì-shíThe tenth

  • 第 一 ,我们 在 宾馆 里。Dì-yī tiān, wǒmen zài bīnguǎn lǐ.On the first day, we will be in the hotel.

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).

Chinese English Example
lóufloor (of a building)七楼qī lóu
céngfloor (of a building)一层yī céng
