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:

第 + Number

• 第一
dì-yī
The first

• 第二
dì-èr
The second

• 第三
dì-sān
The third

### Full Pattern with Measure Words

Typically, this pattern is used together with a measure word to make a complete noun phrase.

#### Structure

第 + Number + Measure Word + Noun

#### Examples

• 我是第一个到公司的人。
Wǒ shì dì-yī gè dào gōngsī de rén.
I'm the first person that came to the office.

• 他要坐早上第一班地铁去上班。
Tāyào zuò zǎoshang dì-yī bān dìtiě qù shàngbān.

• 我的第一个中文老师是美国人。

• 这次比赛，我们班第一，他们班第二。
Zhè cì bǐsài, wǒmen bān dì-yī, tāmen bān dì-èr.
In this contest, our class is the first, their class is the second.

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.

• 第一天，我们在宾馆里。
Dì-yī tiān, wǒmen zài bīnguǎn lǐ.
On the first day [of our trip], we will be in the hotel.

• 来上海以后的第二年，他开了这家公司。

• 这是我第一次去北京。
Zhè shì wǒ dì-yī cì qù Běijīng.
This is my first time going to Beijing.

### 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).

1. 楼 lóu floor (of a building)
• 七楼 qī lóu “floor seven; seventh floor”
1. 层 céng level (of a building)
• 一层 yī céng “level one; first floor”
