When to Drop 的 (de): Close Possession
For close relationships (family, partners, close friends) and institutions (school, work), Chinese drops the possessive 的: it's 我妈, not 我的妈. Keeping 的 sounds oddly distant.
Why this trips learners up
One of the first things you learn is that possession in Chinese uses 的 (de): 我的书 (my book), 你的手机 (your phone). So it feels logical to say 我的妈妈 for “my mom”. Grammatically it isn't broken — but to a native ear it sounds oddly formal, as if you're putting distance between yourself and your own mother.
The fix is counter-intuitive: with close relationships (family, partners, close friends) and institutions you belong to (your school, your company), Chinese drops the 的. It's 我妈, 我女朋友, 我们学校 — just Pronoun + Noun. The closer the bond, the more a 的 feels like a wall. Keep 的 for everything else (我的书, 我的钱).

Common mistakes
Why it happens: With your own family, 的 reads as distance. 我的妈妈 isn't ungrammatical, but it lands like “my mother, the person who…”. Natives just say 我妈妈 — or 我妈.
Why it happens: Institutions you belong to behave the same way. Your school, your company — these are close ties, so the 的 drops: 我们学校, not 我们的学校.
Why it happens: Don't over-correct. The 的-drop is only for close relationships and institutions. An ordinary object — a book, a phone, money — keeps 的: 我的书, never 我书.
Compare & contrast
| Drop 的 (close ties & institutions) | Keep 的 (everything else) | The difference |
|---|---|---|
| 我姐wǒ jiě | 我的手机wǒ de shǒujī | Family is a close bond, so 的 disappears (我姐). A phone is just an object — it keeps 的 (我的手机). |
| 我们公司wǒmen gōngsī | 我的钱wǒ de qián | An institution you're part of drops 的 (我们公司). Money is an ordinary possession — keep 的 (我的钱). |
