I know that, when expressing possessives, we add 的 to the usual personal pronouns, such as 我的.

However, in a question in my grammar textbook I saw:

你爸爸忙吗? = Is your father busy?

Why not "你爸爸忙吗?"?

Are there any other exceptional or particular uses of 的 that are worth being mentioned here?

When 的 is used for possession or 's, it is often omitted in speaking when it's the subject of a sentence. For example:

她(的)家很漂亮/她(的)家很漂亮 = Her house/home is beautiful.
你(的)電腦很慢/你(的)电脑很慢 = Your computer is really slow.
他(的)新車很貴/他(的)新车很贵 = His new car is quite expensive.

But 的 is usually kept when it's the object of a sentence.

我喜歡他的車/我喜欢他的车 = I like his car.

But then, again as in any language, there is always exceptions :(

For example: 我去過他(的)家/我去过他(的)家 = I've been to his house.

And because of this omission, interesting sentences like this one can come up occasionally in daily conversation:

他媽的洋裝很高雅/他妈的洋装很高雅 = His mother's dress is very elegant.

If you say this out loud, most Chinese people would pick up "他媽的" (damn, sh*t, bloody, f*cking depending on context) and think you are cursing for a split second before you finish the sentence. While this is not a serious problem in casual conversation, one way to avoid this awkward confusion is to explicitly say "他媽媽的".

Added simplified Chinese after the original examples in Traditional Chinese as requested.

  • actually, 他妈妈的 is almost the same meaning with 他妈的, oops ...

  • Interesting, I've never come across the usage of 他媽媽的 in offensive/cursing manner. Having said that, if one says "他媽媽的洋裝", it'd be less likely to be taken as offensive when the words come out of your mouth.

  • It depends on the tongue and context. If you say 他妈的洋装 and people talked to feel offensive, then your change to say 他妈妈的洋装 won't help you out of the embarrassment.

  • @Alenanno Yes, I use Traditional characters (^_^) Feel free to drop me a line if you need any help with it.

Both 你爸爸忙吗? and 你的爸爸忙吗? are possible. Perhaps because of high degree of collocation that gets elided. In Chinese it is usually possible to express something similar to a genitive without in between. I think instead of two nouns in a genitive relation, it becomes a single compound noun instead. Semantically equivalent but the grammatical make up behind it is slightly different.


我的国家 > 我国

  • I think 我的国家 is more emotional and usually used in written chinese or you make a speech.

I think the omitting of "的" of possessives in object of a sentence is done by following situations:

  • a person have some relationship with preceding person
  • or just some place after a movement "去、来、上、下、到"
  • or some words preceding by attribute "这,那"


  • places: "去你家","来我国","去他办公室","去他车上","到我这里"
  • relationships: "问她爸","找他小孩",”看望他奶奶“
  • attribute: "坐他那车", "用我这笔"

and add "的" if followed by other things "坐他的车", "找她的笔", "用你的电脑", "讲他的笑话".

and more. you can omit the one if it's still the attribute of following words. "坐他(的)车的后座", "用你(的)电脑的主机", "找她(的)钢笔的套子"

  • May I make a suggestion here. While I find this is a good answer, I think it'd be helpful to those that are learning the language if you could provide English translation for any Chinese examples given in your answer.

Since you are asking "exception in the use of 的", just thought worth mentioning other meanings of here.

  • 的(dí) means indeed. For example: 的确

  • 的(dì) means object/aim/target/goal. For example: 目的
