第 dì

Bamboo slips arranged in an ordered sequence to mark rank or grade.

Ordinal prefix placed before numbers: first, second, third. Bamboo (⺮) over 弟 (order/sequence) — slips filed in numbered order.

Common Usage & Traps

  • 第一 (dì yī) — first
  • 第二天 (dì èr tiān) — the next day
  • 第三天 (dì sān tiān) — day three
  • 第一个 (dì yī ge) — the first one
  • 第一年 (dì yī nián) — the first year
  • 一第 第一

    English says 'number one,' so learners flip the pieces. In Chinese the 第 always comes first, then the number.

  • 第天 第二天

    第 is a hook, not a word. Skip the number and the sentence just dangles there waiting to finish.

  • 一月第一天 一月一号

    Dates, floors and room numbers are names, not rankings, so Chinese drops 第 and lets the number stand alone.

Why does 我第次来中国 sound broken?

第 can't stand alone; it always needs a number attached — 我第一次来中国.

Think of 第 as the '-th' in English 'fourth' or 'fifth.' It is a hook you hang a number on, never a word by itself. So 'my first time in China' is 我第一次来中国, with 一 sitting right after 第. Drop the number and native speakers just hear an unfinished word and wait for you to keep going.

Why does 第二天 mean 'the next day' and not 'the second day'?

In storytelling, 第二天 is how Chinese moves time forward — it's sequencing, not counting.

When someone tells a story, 第一天 sets the scene and 第二天 jumps to what happened after. Chinese literally says 'the second day' where English says 'the next day.' Nobody is ticking off a calendar here; it is just narrative glue holding events in order. The same pattern runs on with 第三天, 第四天 as the story keeps rolling.

Telling a story第一天他去了北京,第二天他回家了。= Day one he went to Beijing; the next day he went home.下一天 = not used this way
Literal calendar第二天 = the second day of a tripassuming 第二天 always means 'next day'
Time words in order第一天 / 第二天 / 第三天第一日 in everyday speech

Why is January 1st 一月一号 and not 一月第一天?

Dates, floors and room numbers drop 第 — the bare number is the name.

第 only shows up when you rank things against each other, like 第一课 or 第三天. A date is not a ranking; it is simply the name of a day, so Chinese says 一月一号. Floors and bus lines work the same way: 一楼 is the first floor and 一号 is the number one. Saying 第一楼 or 第一号 makes it sound like you are calling out race results.

Floors and numbers一楼 = first floor, 一号 = number one第一楼, 第一号
