Chinese Family Terms: A Complete Guide to Kinship Vocabulary (稱謂)

Your Taiwanese host mother has a sister. In English, she’s your aunt. In Mandarin, she might be 阿姨 (āyí), 姑姑 (gūgu), or 姨媽 (yímā) — and picking the wrong one doesn’t just sound foreign, it tells the listener something factually wrong about your family tree.

Dangdai Book 1, Lesson 2 introduces this problem early: older versus younger siblings (哥哥 vs 弟弟, 姐姐 vs 妹妹), then 伯母 for a friend’s mother, then moves on before the system is anywhere near complete. That’s the right call for a first lesson — but it leaves most learners with a vague sense that Chinese kinship terms are “complicated” without the actual logic that would make them easy. This guide gives you that logic.

Why English “Aunt” Doesn’t Translate

English kinship terms are minimal by design: aunt, uncle, cousin, grandparent. Mandarin encodes three variables that English collapses:

• Side of the family. Father’s relatives and mother’s relatives get entirely different words.
• Relative age. A sibling older than you and a sibling younger than you are named differently — and this extends to your parents’ siblings too.
• Blood vs. marriage, and generation. Whether someone married into the family, and which generation they belong to, changes the term again.

This isn’t decorative complexity. Traditionally, it mapped directly onto obligation — who inherited what, who was responsible for whom, who you owed formal respect to at a funeral. The vocabulary survives even where the legal structure behind it hasn’t. Once you see the three variables, the “complicated” system resolves into a small set of repeating rules.

Immediate Family (核心家庭)

The core unit is the one exception to all the complexity below — it’s flat and memorized early:

Term	Pinyin	Meaning
爸爸	bàba	father
媽媽	māma	mother
哥哥	gēge	older brother
弟弟	dìdi	younger brother
姐姐	jiějie	older sister
妹妹	mèimei	younger sister
兒子	érzi	son
女兒	nǚ’ér	daughter

Note the older/younger split on siblings — there is no generic Mandarin word for “brother” or “sister” the way English has one. You always specify which.

Grandparents: The First Side-of-Family Split

This is where 外 (wài, “outside”) enters the system — the single most useful character in the whole chart, because it marks the maternal side everywhere it appears:

Term	Pinyin	Meaning
爺爺	yéye	paternal grandfather
奶奶	nǎinai	paternal grandmother
外公	wàigōng	maternal grandfather (“outside grandfather”)
外婆	wàipó	maternal grandmother (“outside grandmother”)

Your father’s parents are simply 爺爺 and 奶奶 — no qualifier, because patrilineal descent was historically the default. Your mother’s parents are marked as “outside” the family line. It sounds harsh in translation; in practice it’s neutral, everyday vocabulary. In parts of Mainland China, 姥爺 (lǎoye) and 姥姥 (lǎolao) are common alternatives for maternal grandparents — in Taiwan, 外公 and 外婆 are what you’ll actually hear.

Aunts and Uncles: The Full Chart

This is the set that trips up almost every intermediate learner, because four variables stack at once: side, gender, and — for father’s brothers specifically — relative age.

Term	Pinyin	Relationship
伯伯	bóbo	father’s older brother
叔叔	shūshu	father’s younger brother
姑姑	gūgu	father’s sister (either age)
舅舅	jiùjiu	mother’s brother (either age)
阿姨	āyí	mother’s sister (either age)
伯母	bómǔ	wife of father’s older brother
嬸嬸	shěnshen	wife of father’s younger brother
姑丈	gūzhàng	husband of father’s sister
舅媽	jiùmā	wife of mother’s brother
姨丈	yízhàng	husband of mother’s sister

The pattern once you see it: father’s side distinguishes older brother (伯) from younger brother (叔); mother’s side doesn’t bother — 舅舅 covers any maternal uncle, 阿姨 any maternal aunt. Spouses who marry in get a compound term built from the blood relative’s title, which is why 伯母 and 舅媽 both translate to “aunt” in English but are built from entirely different roots.

Cousins: 堂 vs 表

The same side-of-family logic extends one generation down, encoded in a single prefix character:

• 堂 (táng) — cousins on your father’s brothers’ side. 堂哥, 堂弟, 堂姐, 堂妹.
• 表 (biǎo) — cousins on your father’s sisters’ side and all of your mother’s side. 表哥, 表弟, 表姐, 表妹.

In practice: if the connecting relative is a man who kept the family surname (your father or your father’s brothers), the cousin is 堂. If the connecting relative is a woman, or anyone on your mother’s side, the cousin is 表. Older/younger still applies on top, same as siblings.

Taiwan’s Social Extension: Kinship Terms for Strangers

Here’s where this stops being abstract vocabulary and starts being something you use daily on the street. Taiwan extends kinship terms to people you are not related to, as a marker of warmth and respect:

• An older woman running a 便利商店 or noodle stall is often 阿姨, even to adult customers she’s never met.
• A friend’s mother is 伯母 or 阿姨 — you heard this exact usage in Dangdai Lesson 2.
• An older man is 伯伯 or, informally, 阿伯.
• A shop owner’s wife is sometimes 老闆娘 rather than a kinship term, but the same instinct — softening a transactional interaction with a relational term — is at work.

Getting this right makes you sound like someone who has actually lived in Taiwan, not someone who memorized a textbook. Address an obviously young 夜市 vendor as 阿姨 and you’ll get a laugh — read the room the same way you would in English.

How This Maps to Dangdai and TOCFL

Kinship terms are frontloaded in Dangdai Book 1 (Lesson 2) but tested more systematically at TOCFL Band A and reinforced through Band B listening passages, where family narratives are a common prompt type. They resurface constantly in the 成語 tradition too — idioms like 兄友弟恭 (elder brother friendly, younger brother respectful) only make sense once you understand that Mandarin never lets sibling order stay implicit.

If you’re studying with Zhong Chinese, the kinship set from Dangdai Lesson 2 is pre-loaded as an FSRS deck, but the extended chart above — the aunts, uncles, and cousins that Book 1 doesn’t cover — is worth building as a supplementary deck early, since you’ll hear it in real conversation well before your textbook catches up.

A Practical Way to Learn It

Don’t memorize the chart top to bottom. Draw your own family tree in Chinese, label every relative you actually have, and only look up the terms you need. A term attached to your actual grandmother sticks; a term attached to a diagram doesn’t. Once your own family is labeled, extend the exercise to your host family or a classmate’s — that’s usually the first real conversation practice for this vocabulary anyway.
