Family Terms in Mandarin Chinese

In Brief

Mandarin family terms give information that English often leaves unstated. A brother or sister is normally identified as older or younger—哥哥/弟弟 and 姐姐/妹妹—and grandparents have different names on the father's and mother's sides: 爷爷/奶奶 versus 外公/外婆. For close relatives, the possessive marker 的 is often omitted, so 我妈妈 is the usual compact way to say “my mom.”

Overview

Family vocabulary is an A1 topic, but it also reveals an important feature of Mandarin: relationships are often named precisely. English brother, sister, grandfather, and aunt can cover several different relationships. Mandarin often builds age, generation, and side of the family into the word itself. This may seem like extra memorization at first, but each term tells your listener exactly where a person fits in the family.

The beginner set is manageable. Start with parents, the four sibling terms, and the four grandparent terms. These words let you introduce a family member, say who you have in your family, and understand basic questions such as 你有兄弟姐妹吗？ “Do you have any siblings?”

This article uses simplified Chinese characters and standard Mandarin pinyin. Pinyin is a spelling system that shows pronunciation in the Latin alphabet; its tone marks are part of the pronunciation. In real Chinese text, family terms are normally written in characters rather than pinyin.

How It Works

Parents and children

Chinese	Pinyin	English	Note
爸爸	bàba	dad; father	Everyday and warm; second syllable is usually neutral
妈妈	māma	mom; mother	Everyday and warm; second syllable is usually neutral
父亲	fùqīn	father	More formal or written
母亲	mǔqīn	mother	More formal or written
父母	fùmǔ	parents	Common collective term, especially in writing
儿子	érzi	son	子 is normally neutral here
女儿	nǚ'ér	daughter	The apostrophe separates two syllables
孩子	háizi	child; children	Number is understood from context

爸爸 and 妈妈 are the natural first words to learn. They are not childish in the way that some English speakers may perceive daddy or mommy; adults use them normally when talking about their own parents. 父亲 and 母亲 sound more formal and are common in writing, biographies, official contexts, or more detached descriptions.

Mandarin nouns do not usually change form for singular and plural. 孩子 can therefore mean “child” or “children.” A number and a measure word—a linking word used when counting a noun—make the quantity clear: 一个孩子 “one child,” 两个孩子 “two children.”

Older and younger siblings

English lets you say brother or sister without mentioning age. Ordinary Mandarin usually chooses one of four terms according to the sibling's age relative to the person whose sibling they are.

Chinese	Pinyin	English	Age relationship
哥哥	gēge	older brother	Older than the person being discussed
弟弟	dìdi	younger brother	Younger than the person being discussed
姐姐	jiějie	older sister	Older than the person being discussed
妹妹	mèimei	younger sister	Younger than the person being discussed
兄弟姐妹	xiōngdì jiěmèi	siblings; brothers and sisters	Inclusive collective expression
兄弟	xiōngdì	brothers; brothers and close male companions	Meaning depends on context
姐妹	jiěmèi	sisters; close female friends	Meaning depends on context

The reference point matters. If Li Ming is older than his sister, she calls him 哥哥, while he calls her 妹妹. Age is not an optional descriptive detail added to a neutral word; it is part of the basic kinship term.

The repeated-looking forms are full words, not plurals. In ordinary speech, the second syllable is commonly pronounced with a neutral tone: gēge, dìdi, jiějie, mèimei. Learn the whole spoken word rather than pronouncing both written syllables with equally strong citation tones.

Paternal and maternal grandparents

Mandarin distinguishes grandparents on the father's side from grandparents on the mother's side.

Chinese	Pinyin	English	Side of family
爷爷	yéye	paternal grandfather	Father's father
奶奶	nǎinai	paternal grandmother	Father's mother
外公	wàigōng	maternal grandfather	Mother's father
外婆	wàipó	maternal grandmother	Mother's mother
祖父	zǔfù	paternal grandfather	Formal or written
祖母	zǔmǔ	paternal grandmother	Formal or written
外祖父	wàizǔfù	maternal grandfather	Formal or written
外祖母	wàizǔmǔ	maternal grandmother	Formal or written

A useful memory aid is that 外 means “outside” or “outer” in many contexts; in these traditional kinship terms, it marks the maternal branch. Treat that as a vocabulary clue, not as a judgment about the closeness or importance of maternal grandparents.

In parts of northern China, you will also hear 姥爷 (lǎoye) for maternal grandfather and 姥姥 (lǎolao) for maternal grandmother. 外公/外婆 are widely understood, but family and regional habits vary.

Possession with 的

The basic possessive pattern is:

person + 的 + family term

• 我的妈妈 — my mom
• 他的姐姐 — his older sister
• 小王的爷爷 — Xiao Wang's paternal grandfather

With close personal relationships, Mandarin often omits 的:

• 我妈妈 — my mom
• 他姐姐 — his older sister
• 我们老师 — our teacher

Both 我妈妈 and 我的妈妈 are grammatical. The version without 的 is especially natural when simply identifying your own close relative. Keeping 的 can make the possession more explicit, add contrast, or fit a heavier phrase: 这是我的妈妈，不是他的妈妈。 “This is my mom, not his.” Beginners can safely use 的, but should learn to recognize the frequent shorter pattern.

Basic sentence patterns

Family terms behave like nouns (words for people, places, things, or ideas). They fit into several useful A1 patterns:

• A 是 B — A is B: 她是我姐姐。 “She is my older sister.”
• A 有 B — A has B: 我有一个弟弟。 “I have a younger brother.”
• 这是 B — This is B: 这是我奶奶。 “This is my paternal grandmother.”
• B + adjective — describing B: 我妹妹很可爱。 “My younger sister is very cute.”

Use 个 as the general measure word when counting many family members: 一个哥哥, 两个妹妹. With 两, not normally 二, before a measure word: 两个姐姐 “two older sisters.” In casual speech, the measure word may disappear in some set-like statements, but 我有一个弟弟 is the dependable beginner pattern.

Examples in Context

Mandarin Chinese	Pinyin	English	Note
这是我爸爸。	Zhè shì wǒ bàba.	This is my dad.	的 is omitted naturally
我妈妈是老师。	Wǒ māma shì lǎoshī.	My mom is a teacher.	Identity uses 是
你有兄弟姐妹吗？	Nǐ yǒu xiōngdì jiěmèi ma?	Do you have any siblings?	A common general question
我有一个哥哥和一个妹妹。	Wǒ yǒu yí ge gēge hé yí ge mèimei.	I have an older brother and a younger sister.	一 changes in connected speech before 个
她是我姐姐，不是我妹妹。	Tā shì wǒ jiějie, bú shì wǒ mèimei.	She is my older sister, not my younger sister.	Contrasts age relationship
我弟弟今年十岁。	Wǒ dìdi jīnnián shí suì.	My younger brother is ten this year.	No form of “to be” before age
我姐姐在北京工作。	Wǒ jiějie zài Běijīng gōngzuò.	My older sister works in Beijing.	Close-relative 的 omitted
爷爷奶奶住在上海。	Yéye nǎinai zhù zài Shànghǎi.	My paternal grandparents live in Shanghai.	Possessor is clear from context
外公外婆明天来。	Wàigōng wàipó míngtiān lái.	My maternal grandparents are coming tomorrow.	Maternal pair
这是我妈妈的爸爸，也就是我外公。	Zhè shì wǒ māma de bàba, yě jiù shì wǒ wàigōng.	This is my mother's father—in other words, my maternal grandfather.	Shows the relationship explicitly
他们有两个女儿。	Tāmen yǒu liǎng ge nǚ'ér.	They have two daughters.	两 + measure word
你妹妹叫什么名字？	Nǐ mèimei jiào shénme míngzi?	What is your younger sister's name?	Literally asks what she is called

Translations naturally add my where Mandarin can leave the owner understood. For example, 爷爷奶奶住在上海 will normally refer to the speaker's paternal grandparents when the conversation is about the speaker's family.

Common Mistakes

Using one general word for every brother or sister

• Wrong: 我的 brother 是学生。
• Right: 我哥哥是学生。 or 我弟弟是学生。
• Why: In an ordinary Mandarin family context, choose 哥哥 if he is older and 弟弟 if he is younger. There is no equally neutral everyday singular equivalent of English brother.

Reversing the grandparent terms

• Wrong: 我妈妈的妈妈是我奶奶。
• Right: 我妈妈的妈妈是我外婆。
• Why: 奶奶 is your father's mother; 外婆 is your mother's mother. Learn the terms as two pairs: father → 爷爷/奶奶, mother → 外公/外婆.

Treating repeated syllables as a plural

• Wrong idea: 哥哥 means “brothers” because 哥 appears twice.
• Right: 哥哥 normally means “older brother,” singular unless context says otherwise.
• Why: The repetition is part of the kinship word. To say “two older brothers,” use 两个哥哥.

Adding 是 before an age

• Wrong: 我妹妹是八岁。
• Right: 我妹妹八岁。 or 我妹妹今年八岁。
• Why: Mandarin normally states age directly; 是 is not a general-purpose copy of English is.

Overusing or fearing 的

• Awkward in a simple introduction: 这是我的妈妈。 is correct, but 这是我妈妈。 is often more conversational.
• Right when contrast is intended: 这是我的妈妈，不是他的妈妈。
• Why: 的 is often optional with close family terms, not always forbidden. Meaning, emphasis, and phrase length affect the choice.

Using 二 before a measure word

• Wrong: 我有二个姐姐。
• Right: 我有两个姐姐。
• Why: Use 两 before a measure word such as 个 in ordinary counting. 二 remains the digit “two” in numbers, dates, room numbers, and similar sequences.

Usage Notes

Talking about someone versus addressing them

A kinship term can identify a person and can also be used to address that person directly. A child may call out 妈妈！ “Mom!” or 爷爷！ “Grandpa!” without a pronoun. Chinese also extends some family-like terms beyond literal relatives. Children may be taught to call an adult 叔叔 “uncle” or 阿姨 “auntie,” and 哥哥/姐姐 can address or describe a slightly older young person in friendly contexts.

These extended uses depend on age, setting, region, and the relationship between speakers. As a learner, do not assign a family-style title to every stranger automatically. Follow how the people around you introduce themselves and address one another.

Family units and word order

Pairs are commonly said without 和 “and”: 爸爸妈妈 “dad and mom,” 爷爷奶奶, and 外公外婆. 爸爸和妈妈 is also correct, especially when the two people are being contrasted or treated separately. The compact pair sounds like a familiar unit.

To ask broadly about siblings, 你有兄弟姐妹吗？ is more natural than listing all four terms every time. In your answer, however, the specific age terms are useful: 我没有哥哥，但是有一个弟弟。 “I don't have an older brother, but I have a younger brother.”

Titles, names, and reference points

The age distinction belongs to the relationship, not to the speaker's opinion. 我哥哥 means a male sibling older than me. 小李的姐姐 means a female sibling older than Xiao Li, even if she is younger than the speaker. Always calculate “older” or “younger” from the person whose family relationship is being described.

Beyond the Basics: The Wider Kinship System

You do not need to master the whole kinship system at A1. Still, you will soon notice that Mandarin distinguishes many relationships that English groups under aunt, uncle, or cousin.

Chinese	Pinyin	Approximate English	Precise relationship
伯伯	bóbo	uncle	Father's older brother
叔叔	shūshu	uncle	Father's younger brother; also a polite family-like address
姑姑	gūgu	aunt	Father's sister
舅舅	jiùjiu	uncle	Mother's brother
姨妈 / 阿姨	yímā / āyí	aunt	Mother's sister; 阿姨 also has broader social uses
丈夫	zhàngfu	husband	More formal/neutral than some colloquial alternatives
妻子	qīzi	wife	Neutral, common in writing and careful speech

Cousin terms can additionally encode whether the connection is through the paternal male line or another branch, as well as gender and relative age. Usage can vary among families and regions. Rather than trying to memorize the entire system in one sitting, learn each term with a small relationship map: “my mother's younger sister,” not merely “aunt.”

Kinship terms also interact with social hierarchy and politeness. Words such as 叔叔, 阿姨, 哥哥, and 姐姐 may create warmth or acknowledge an age relationship outside the literal family. They are not exact substitutes for English Mr., Ms., sir, or ma'am. Their appropriateness depends on social context, and modern preferences differ.

Formal writing favors collective or formal forms such as 父母, 父亲, 母亲, 祖父, and 祖母 more than ordinary family conversation does. A person who says 我妈妈 in conversation may write 我的母亲 in a formal account. This is a register difference—a difference in language chosen for casual, formal, spoken, or written situations—not a change in the family relationship.

Practice Tips

1. Draw a two-branch family tree. Put your father's parents under 爷爷/奶奶 and your mother's parents under 外公/外婆. Add siblings with an up arrow for 哥哥/姐姐 and a down arrow for 弟弟/妹妹.
2. Practice complete introductions, not isolated lists. Say 这是我妈妈, 我有一个姐姐, and 我弟弟今年十五岁. This rehearses the family word together with useful sentence patterns and measure words.
3. Learn sound and characters together. Read each repeated-syllable word aloud with a light neutral second syllable, then cover the pinyin and identify the characters. Review contrasting pairs together: 哥哥—弟弟, 姐姐—妹妹, 爷爷—外公, 奶奶—外婆.
