Which side?
Your father's parents and your mother's parents are four different words, not two.
奶奶vs外婆
paternal vs maternal grandmother
亲属称谓 · Chinese kinship
Chinese family tree:
every relative, named
English has one word for grandmother, one for uncle, one for cousin. Chinese has two, five and eight — because every term tells you which side of the family, whether they are older or younger, and whose family you married into.
Chinese kinship is not a vocabulary list. It is a coordinate system: every term answers whose side, which generation, and older or younger.
This page is built as a map, not a list. Below: an interactive family tree, the eight words for “cousin”, the in-law terms that change with your gender, and all 73 terms in one reference. Every card is clickable.

02 — The system
Four questions English doesn't ask
Learn the questions, not just the words. Once you can answer them, you can predict a term you have never seen — and understand why a dictionary translation so often misses.
Older or younger?
There is no neutral “brother”. The word itself states whether the person is older or younger than you.
哥哥vs弟弟
older vs younger brother
Inner or outer line?
Children of your son and children of your daughter split; so do your brother's and sister's children.
孙子vs外孙
son's son vs daughter's son
Married into whose family?
In-law terms are not symmetrical. Some depend on whether the speaker is the husband or the wife.
公公vs岳父
husband's father vs wife's father
Ten English words, 32 Chinese terms
These ten English words cover at least 32 distinct relationships in Mandarin. The table is the shortest summary of why this page exists.
| English | Mandarin terms | How many |
|---|---|---|
| grandmother | 奶奶 · 外婆 | 2 |
| grandfather | 爷爷 · 外公 | 2 |
| brother | 哥哥 · 弟弟 | 2 |
| sister | 姐姐 · 妹妹 | 2 |
| uncle | 伯伯 · 叔叔 · 舅舅 · 姑父 · 姨父 | 5 |
| aunt | 伯母 · 婶婶 · 姑姑 · 舅妈 · 姨妈 | 5 |
| cousin | 堂哥 · 堂弟 · 堂姐 · 堂妹 · 表哥 · 表弟 · 表姐 · 表妹 | 8 |
| nephew | 侄子 · 外甥 | 2 |
| niece | 侄女 · 外甥女 | 2 |
| grandson | 孙子 · 外孙 | 2 |
Plus the generic 阿姨 — used for your mother's sister, for any woman of your parents' generation, and for domestic helpers.
03 — Cousins
Eight words for “cousin”
This is the clearest example of the system at work. Two questions — 堂 or 表, older or younger — plus gender give eight words where English has one.
| Cousin type | Male · older | Male · younger | Female · older | Female · younger |
|---|---|---|---|---|
| 堂father's brother's children | 堂哥táng gē | 堂弟táng dì | 堂姐táng jiě | 堂妹táng mèi |
| 表everyone else's children | 表哥biǎo gē | 表弟biǎo dì | 表姐biǎo jiě | 表妹biǎo mèi |
堂 The same surname
堂 cousins are your father's brothers' children. You share a paternal grandfather — and, traditionally, the same surname. The word 堂 originally meant the hall of the family house: the people under the same roof.
表 Everyone else
表 covers your father's sisters' children and all of your mother's siblings' children. The character originally referred to the outer surface of a garment — the “outside” branch. It is not a demotion, just a different line.
The full guide covers all eight words with examples: Cousin in Chinese — eight words for one.
04 — Aunts & uncles
Five uncles, five aunts
English “uncle” covers four different men and two of them are split by age. Chinese gives each relative a precise address — and each spouse a matching term.
| Relative | Father's brother | Father's sister | Mother's brother | Mother's sister |
|---|---|---|---|---|
| The relative | 伯伯 older 叔叔 younger |
姑姑 | 舅舅 | 姨妈 |
| Their spouse | 伯母 older 婶婶 younger |
姑父 | 舅妈 | 姨父 |
Ranked, not just named
If your father has three brothers, they are 大伯, 二伯 and 三叔 — the number comes from their birth order in the family, not from your relationship to them. The same pattern gives 大姨/小姨 and 大舅/二舅.
Terms that travel
叔叔 and 阿姨 are also the default polite words for unrelated adults of your parents' age. 爷爷 and 奶奶 work the same way for people of grandparent age. The kinship system doubles as a public etiquette system.
Go deeper: Uncle in Chinese — five words · Aunt in Chinese — five words.
05 — In-laws
The word depends on who you are
This is the part phrasebooks skip. Chinese in-law terms are not symmetrical: the same relationship gets a different word depending on whether you are the wife or the husband.
| In-law | A woman speaking her husband's parents |
A man speaking his wife's parents |
|---|---|---|
| Father-in-law | 公公gōng gong | 岳父yuè fù |
| Mother-in-law | 婆婆pó po | 岳母yuè mǔ |
| Spouse's sibling | Your husband's… a woman speaking |
Your wife's… a man speaking |
|---|---|---|
| Older brother | 大伯子 | 大舅子 |
| Younger brother | 小叔子 | 小舅子 |
| Older sister | 大姑子 | 大姨子 |
| Younger sister | 小姑子 | 小姨子 |
The other direction
Your child's spouse has their own pair of terms: 女婿 (daughter's husband) and 儿媳 (son's wife). Your siblings' spouses split by age: 嫂子 / 弟媳 for brothers' wives, 姐夫 / 妹夫 for sisters' husbands.
And the two families?
Once your child marries, the two sets of parents are 亲家 (qìng jia — not qīn jiā). It is a relationship word, not an address: you would not call the other father “亲家” to his face unless you are close.

祖辈Grandparents
Four words where English has two — and one prefix, 外, that changes everything.
| English | Term | Pinyin | Who exactly | Notes |
|---|---|---|---|---|
| paternal grandfather | yé ye | your father's father | Also 祖父 zǔfù in formal writing. If your father has brothers, they are ranked separately — 爷爷 is the grandfather, not an uncle. | |
| paternal grandmother | nǎi nai | your father's mother | Also 祖母 zǔmǔ. In Min- and Yue-speaking regions you will also hear 阿嬷 āmā or 阿婆 āpó. | |
| maternal grandfather | wài gōng | your mother's father | In northern China the everyday word is 姥爷 lǎoye. Formal: 外祖父 wàizǔfù. 外 marks the mother's side. | |
| maternal grandmother | wài pó | your mother's mother | In northern China: 姥姥 lǎolao. Formal: 外祖母 wàizǔmǔ. | |
| great-grandfather | zēng zǔ fù | your grandfather's father | For the mother's side, add 外: 外曾祖父. Most families simply say 太爷爷 in speech. | |
| great-grandmother | zēng zǔ mǔ | your grandfather's mother | Also 太奶奶 in everyday northern speech. |
父母Parents
The pair every learner meets first — with a formal and a spoken register.
| English | Term | Pinyin | Who exactly | Notes |
|---|---|---|---|---|
| dad, father | bà ba | your father | 父亲 fùqīn in writing or formal speech; 爸 bà is the short form. 老爸 is affectionate, a little playful. | |
| mom, mother | mā ma | your mother | 母亲 mǔqīn formal; 妈 mā short. 老妈 is affectionate, a little playful. | |
| parents | fù mǔ | your father and mother together | Collective and slightly formal. In speech people say 爸妈 bà mā. |
兄弟姐妹Siblings
Age is built into the word: there is no neutral word for “brother” or “sister”.
| English | Term | Pinyin | Who exactly | Notes |
|---|---|---|---|---|
| older brother | gē ge | a brother older than you | Using 哥哥 for someone younger is a real, if small, misstep: the word is a claim about relative age. | |
| younger brother | dì di | a brother younger than you | ||
| older sister | jiě jie | a sister older than you | ||
| younger sister | mèi mei | a sister younger than you | ||
| siblings | xiōng dì jiě mèi | your brothers and sisters collectively | 兄弟 alone means “brothers”; 姐妹 alone means “sisters”. 兄弟 is also used loosely between male friends. |
自己的家Your own household
Spouse and children — the terms you will use about your own home.
| English | Term | Pinyin | Who exactly | Notes |
|---|---|---|---|---|
| husband | zhàng fu | your husband | 老公 lǎogōng is the everyday word; 先生 xiānsheng can also mean “husband” in older usage, but usually means “Mr.”. | |
| wife | qī zi | your wife | 老婆 lǎopo everyday; 太太 tàitai a little more formal or old-fashioned. | |
| son | ér zi | your son | ||
| daughter | nǚ ér | your daughter | ||
| child, children | hái zi | your child or children | 小孩 xiǎohái is “kid”. 独生子女 dúshēngzǐnǚ is the term for an only child. |

| English | Term | Pinyin | Who exactly | Notes |
|---|---|---|---|---|
| grandson (son's son) | sūn zi | your son's son | Traditionally the “inner” grandson. Your daughter's son is 外孙 — see below. | |
| granddaughter (son's daughter) | sūn nǚ | your son's daughter | ||
| grandson (daughter's son) | wài sūn | your daughter's son | 外 marks the daughter's side. Many families now use 孙子 for both; follow the family. | |
| granddaughter (daughter's daughter) | wài sūn nǚ | your daughter's daughter |
父系：伯叔姑Father's brothers and sister
One uncle for older, one for younger — plus the aunt whose children are 表, not 堂.

07 — Regional variation
姥姥 or 外婆?
Standard Mandarin is not the whole story. The most visible split is the maternal grandparents: the north says 姥姥/姥爷, most of the south and nearly all writing says 外婆/外公.
| Concept | Northern speech | Standard / southern | Formal writing |
|---|---|---|---|
| Maternal grandmother | 姥姥 lǎolao | 外婆 wàipó | 外祖母 |
| Maternal grandfather | 姥爷 lǎoye | 外公 wàigōng | 外祖父 |
| Father's sister | 姑妈 gūmā | 姑姑 gūgu | 姑母 |
| Wife's mother | 丈母娘 zhàngmǔniáng | 岳母 yuèmǔ | 岳母 |
In Min- and Yue-speaking regions you will also hear 阿嬷 (ā-mā) and 阿婆 (ā-pó) for grandmother; in parts of the Wu-speaking area, 阿娘. Regional forms are not “wrong Mandarin” — they are the family's actual language. If you are meeting someone's relatives, ask which word the family uses before you use one.
There is also a generation gap. Younger urban families are more likely to use 爷爷奶奶 for both sides, or to mix 姥姥 with 外婆 depending on which grandparent is present. The system in this page is the standard one; real families negotiate it.
More on the split: Grandmother in Chinese · Grandfather in Chinese.
08 — Culture
What the words assume
Kinship terms are a compressed description of how a family is organised. Six things the vocabulary quietly assumes.
长幼有序 · Age is order
Chinese kinship encodes birth order because it organises obligation: who bows first, who is addressed with which term, who is expected to look after whom. Calling someone 哥哥 is a small claim about seniority, not just a label.
内外有别 · Inner and outer
The prefix 外 (outer) marks the mother's side: 外公, 外婆, 外孙, 外甥. It comes from a patrilineal system in which the father's line carried the surname and the ancestral hall. It does not mean “less loved” — but it does record a structure.
称呼 · Address vs reference
You call your father's younger brother 叔叔, but when explaining him to a friend you might say 我爸爸的弟弟. Some words exist only for reference, not address — the formal 家父 (“my father”) or 令尊 (“your father”) belong in letters, not at the dinner table.
排行 · Numbers in the name
Families rank siblings: 二叔, 三姨, 大哥, 小妹. The number travels with the term and tells you where someone sits in the family, not how old they are in absolute terms.
家谱 · The written line
Traditional genealogy books recorded generations and often assigned a generation character (辈分字) to every name in the same generation — which is why cousins can share the middle character of their given names.
What is changing
Smaller families, migration and intermarriage have thinned some distinctions. 堂 and 表 are still taught, but casual speech sometimes blurs them; 外 is increasingly dropped by young parents. Precision is appreciated; flexibility is normal.

10 — Questions
What learners ask most
What is “family tree” in Chinese?
家谱 (jiāpǔ) is the traditional written genealogy — a clan's record of names and generations, sometimes kept for centuries. For a diagram of who is who, people say 家庭关系图 (jiātíng guānxì tú) or 亲属关系图 (qīnshǔ guānxì tú). The word 家谱 carries more weight than “chart”: many families had one, and generation names (辈分) were often fixed in advance.
Why does Chinese have different words for each grandmother?
Because the language records which side of the family a person belongs to. 奶奶 is your father's mother; 外婆 — or 姥姥 in the north — is your mother's mother. The same logic gives 爷爷/外公 for grandfathers, 孙子/外孙 for grandsons, and 侄子/外甥 for nephews. English leaves the side unspecified; Chinese makes you choose.
What is the difference between 堂 and 表 cousins?
堂 cousins are your father's brothers' children: you share a paternal grandfather, and usually a surname. Everyone else is 表 — your father's sisters' children and all your mother's siblings' children. So one English “cousin” maps to eight Chinese words, four 堂 and four 表, each also marked for older/younger and male/female.
Do Chinese people call their in-laws 爸爸 and 妈妈?
Often, yes. After marriage many people address their spouse's parents as 爸/妈 in everyday family settings, while using 公公/婆婆 or 岳父/岳母 when referring to them to other people. The reference terms depend on the speaker's gender: a woman says 公公/婆婆, a man says 岳父/岳母.
Is 外公 / 外婆 rude?
No. 外 literally means “outside” and marks the mother's side in a traditionally patrilineal system; it is not an insult, and these are standard, affectionate everyday words across most of southern and central China. Some families today prefer 爷爷奶奶 for both sets of grandparents, and northern families use 姥姥/姥爷. Follow the family's own usage.
How many Chinese kinship terms are there?
The classical dictionary 尔雅 (Ěryǎ) devotes a whole chapter to kinship and lists dozens; historical systems with ranked siblings, concubines and multi-generation households produced hundreds. For modern Mandarin, about 50–70 terms cover everyday family life — this page lists 73. You do not need all of them at once: start with your own family.
How do I address older strangers?
Borrow a kinship term as a politeness marker: 爷爷/奶奶 for people of grandparent age, 叔叔/阿姨 for your parents' generation, 大哥/大姐 among peers. 师傅 (shīfu) works for workers and drivers; 先生/女士 is the neutral formal option.
