Chinese words for family members: complete guide with pronunciation

How Chinese tones work — and why they matter for family vocabulary

Mandarin Chinese has four tones plus a neutral (fifth) tone. Every syllable in every word carries one of these tones, and changing the tone changes the meaning of the word. This is not a small detail — it's baked into how the language works, and it applies to every family term in this guide.

Here's the quick version:

• First tone (ā) — high and level. Hold your voice steady at the top of your range. Example: 媽 (mā), mother.
• Second tone (á) — rising. Your pitch climbs from mid to high, like the end of a question in English. Example: 爺 (yé), grandfather.
• Third tone (ǎ) — dipping. Pitch starts mid, falls to low, then rises. In fast speech before another syllable, it often only falls. Example: 姐 (jiě), older sister.
• Fourth tone (à) — falling sharply. Starts high and drops fast, like a firm statement. Example: 爸 (bà), father.
• Neutral tone (a) — short and light, with no set pitch. It often follows a full-tone syllable in reduplicated words. Example: the second syllable of 爸爸 (bàba).

The practical takeaway: learn each family word with its tones from the start. Once the wrong tone becomes a habit, it's harder to fix. The good news is that many family terms share patterns — reduplicated words like 爸爸, 媽媽, 哥哥 are particularly easy to remember because the second syllable usually softens to a neutral tone in everyday speech.

Great-grandparents — 曾祖父 and 曾外祖父

曾祖父 (zēng zǔ fù) — paternal great-grandfather. This is the formal written term for your father's father's father. In spoken Taiwanese Mandarin, you're more likely to hear 太爺爺 (tài yé ye). The character 曾 (zēng) signals a generation above the grandparent level — it appears in all formal great-grandparent terms.

曾外祖父 (zēng wài zǔ fù) — maternal great-grandfather. The 外 (wài, meaning "outside" or "external") flags the maternal line. The colloquial form is 太外公 (tài wài gōng). Both great-grandfather terms are formal and most often appear in genealogical records, obituaries, or careful written speech; everyday family conversations usually use the shorter spoken forms.

曾祖母 (zēng zǔ mǔ) — paternal great-grandmother, with 太奶奶 (tài nǎi nai) as the spoken equivalent. 曾外祖母 (zēng wài zǔ mǔ) — maternal great-grandmother, spoken as 太外婆 (tài wài pó).

Grandparents — four distinct words for four distinct roles

English uses "grandfather" and "grandmother" for both sides of the family. Mandarin doesn't — it has four separate words, one per grandparent, and which one you use depends entirely on whether you're referring to your father's side or your mother's side.

祖父 (zǔ fù) — paternal grandfather. Used in formal and written contexts. In everyday speech, almost everyone says 爺爺 (yé ye) instead — it's warmer and more natural. Both syllables use the second tone (yé), though in natural speech the second syllable often softens to a neutral tone.

外祖父 (wài zǔ fù) — maternal grandfather, formal. The everyday form is 外公 (wài gōng), which you'll hear in Taiwan and southern China. Some northern Mandarin speakers say 姥爺 (lǎo ye) instead. The 外 prefix marks the maternal line throughout the kinship system — once you learn to recognise it, reading a Chinese family tree becomes much more straightforward.

祖母 (zǔ mǔ) — paternal grandmother, formal. The spoken form is 奶奶 (nǎi nai) — both syllables use the third tone, though the second typically softens. Nǎi nai is one of the first Chinese words many children learn.

外祖母 (wài zǔ mǔ) — maternal grandmother, formal. The everyday form is 外婆 (wài pó) in Taiwan and most of southern China, or 姥姥 (lǎo lao) in the north. Both are widely understood. Coachers programs, which focus on Taiwanese Chinese, primarily use 外婆, but heritage learners may hear 姥姥 from family members with mainland northern backgrounds.

Parents — 父親/爸爸 and 母親/媽媽

父親 (fù qīn) — father, formal written term. You'd see this on a form or in a formal document. 爸爸 (bàba) is how almost everyone actually says it. The first syllable carries the fourth tone (falling sharply), and the second softens to a neutral tone in natural speech. It's one of those words most Chinese children say long before they can read.

母親 (mǔ qīn) — mother, formal. 媽媽 (māma) is the everyday form — first tone on both syllables, the second typically neutral in speech. The repeated first-tone syllable gives it that steady, high pitch that sounds distinctly different from 媽 said with any other tone. (The single character 馬 (mǎ) means horse; tones matter.)

Siblings — older, younger, and why order matters

Mandarin has four sibling words rather than two, because birth order is built into the vocabulary. You can't just say "sister" — you have to say which kind.

哥哥 (gēge) — older brother. Both syllables are the same character 哥, pronounced with first tone on the first syllable and neutral tone on the second in everyday speech. Calling someone 哥哥 signals that they hold the older, protective position in the sibling hierarchy.

弟弟 (dìdi) — younger brother. Fourth tone on the first syllable, neutral on the second. The character 弟 (dì) carries the sense of someone who came after, who is still learning from the older sibling.

姐姐 (jiějie) — older sister. Third tone on the first syllable (jiě), neutral on the second. The character includes the 女 (nǚ) radical on the left, meaning "female," which you'll find in many Chinese words related to women and family roles.

妹妹 (mèimei) — younger sister. Fourth tone on the first syllable (mèi), neutral on the second. This is the word the existing high-impression query "younger sister in Chinese" is looking for. For a deeper look at 妹妹 — its stroke order, its character structure, and sentences for practice — see our dedicated guide to younger sister in Chinese.

All four sibling words are reduplicated: the same syllable written twice. That doubling is a Mandarin pattern that makes words feel intimate and conversational rather than formal. The same pattern appears in 爸爸, 媽媽, and many other family terms.

Aunts and uncles — the most complex part of the system

This is where Chinese kinship vocabulary gets genuinely intricate. Mandarin distinguishes aunts and uncles by which parent's side they belong to, whether they're male or female, and — for paternal uncles — whether they're older or younger than your father. English uses "uncle" and "aunt" for all of them. Chinese does not.

Paternal uncle (father's older brother): 伯父 (bó fù), or more informally 大伯 (dà bó). The 伯 character signals seniority — an older male relative on the paternal side. First tone (bó) followed by fourth tone (fù).

Paternal uncle (father's younger brother): 叔父 (shū fù), or in everyday speech 叔叔 (shūshu). First tone on both syllables, second softened in natural speech. This is the term heritage learners in Taiwan most commonly use for their father's younger brothers.

Paternal aunt (father's sister): 姑姑 (gūgu), formally 姑媽 (gū mā). First tone on both syllables of 姑姑, second softened. The 姑 character is specific to the paternal aunt relationship — it doesn't appear in the maternal aunt terms at all.

Maternal uncle (mother's brother): 舅舅 (jiùjiu). Fourth tone on the first syllable (jiù), neutral on the second. There's just one term regardless of whether the maternal uncle is older or younger than your mother — no distinction like the paternal uncle split.

Maternal aunt (mother's sister): 阿姨 (āyí), formally 姨媽 (yí mā). 阿姨 uses first tone then second tone and is the standard everyday form in Taiwan. It's also commonly used as a polite form of address for any adult woman who is a generation older than you — not just a biological aunt.

Cousins — 堂 versus 表

In English, a cousin is a cousin. In Mandarin, there are two entirely different categories, and which one applies depends on which side of the family the cousin comes from.

堂 cousins (táng) — children of your father's siblings. These are your paternal cousins. The term further divides by gender and birth order relative to you: 堂哥 (táng gē) is a paternal male cousin older than you, 堂弟 (táng dì) is a paternal male cousin younger than you, 堂姐 (táng jiě) is a paternal female cousin older than you, and 堂妹 (táng mèi) is a paternal female cousin younger than you.

表 cousins (biǎo) — children of your mother's siblings, or sometimes children of your father's sisters. These are your maternal cousins, and they follow the same birth-order and gender logic: 表哥 (biǎo gē), 表弟 (biǎo dì), 表姐 (biǎo jiě), 表妹 (biǎo mèi). The biǎo/táng distinction is one of those things that trips up English-speaking learners because there's no equivalent in English — you have to learn to think about which family line a cousin comes from.

Why Chinese kinship terms are so specific — the cultural context

The precision built into Chinese family vocabulary isn't arbitrary. It reflects a way of organising social relationships that has deep roots in Chinese philosophical and social history. Classical Chinese thought placed the family at the centre of all social order. Different relationships carried different obligations, modes of address, and expectations of behaviour. The language grew to encode those distinctions directly — so that you couldn't speak about a family member without simultaneously locating that person in the family structure.

The paternal/maternal split is the most obvious example. The character 外 (wài), meaning "outside," appears in 外公, 外婆, 外祖父, 外祖母, and all the 外 great-grandparent terms. It marks the maternal line as belonging to a different family — in traditional Chinese households, the paternal grandparents often lived with the family, while the maternal grandparents were visited. Modern families in Taiwan and across Chinese-speaking communities have largely left that household structure behind, but the vocabulary remains embedded in everyday speech.

The older/younger sibling distinction reflects a similar logic. 哥哥 (older brother) and 姐姐 (older sister) carry implicit expectations of guidance and responsibility. 弟弟 (younger brother) and 妹妹 (younger sister) carry expectations of deference and learning. These aren't just words — they describe a relationship and the roles that come with it. For heritage learners, understanding this context helps explain why getting the right term matters so much at a family gathering: using the wrong one doesn't just sound odd, it mislocates the relationship entirely.

FAQ

How do you say great-grandfather in Chinese?

Paternal great-grandfather is 曾祖父 (zēng zǔ fù) in formal Mandarin. The colloquial spoken form is 太爺爺 (tài yé ye). Maternal great-grandfather is 曾外祖父 (zēng wài zǔ fù), or 太外公 (tài wài gōng) in everyday speech.

What is the difference between 爺爺 and 外公?

爺爺 (yé ye) is the everyday term for paternal grandfather — your father's father. 外公 (wài gōng) is maternal grandfather — your mother's father. The character 外 (wài) means "outside" or "external," signalling that the maternal grandparents belong to a different family line. Both terms are standard in Taiwan.

Why does Chinese have different words for older and younger siblings?

Mandarin encodes birth order directly into sibling vocabulary because relative age shapes how people address and treat each other in Chinese family culture. 哥哥 (gēge) is older brother, 弟弟 (dìdi) is younger brother, 姐姐 (jiějie) is older sister, and 妹妹 (mèimei) is younger sister. There's no single word for "sibling" in Mandarin without specifying both gender and whether the person is older or younger than you.

What is the difference between 堂 and 表 cousins in Chinese?

堂 cousins are cousins on the paternal side — children of your father's siblings. 表 cousins are cousins on the maternal side — children of your mother's siblings. Chinese further distinguishes by birth order and gender, so a paternal male cousin older than you is 堂哥 (táng gē) and a maternal female cousin younger than you is 表妹 (biǎo mèi).

How do Chinese tones affect family vocabulary?

Every family term carries specific tones that must be pronounced correctly. 媽媽 (māmā) is "mother" with first tones; say it with a different tone and you've said something else. Tone marks in pinyin show which tone to use: ā is first (high, level), á is second (rising), ǎ is third (dipping), à is fourth (falling), and a without a mark is neutral (light and short). Learning tones alongside vocabulary — not as a separate exercise — is the most reliable way to build correct pronunciation habits from the start.
