Grandma in Chinese: Nai Nai vs Lao Lao
There is no single word for grandma in Chinese, and the reason is the useful part. 奶奶 (nǎinai) is your father’s mother. 姥姥 (lǎolao) or 外婆 (wàipó) is your mother’s mother — lǎolao in the north, wàipó in the south, same grandmother. Mandarin makes you choose a side before you can open your mouth, which sounds inconvenient and is in fact enormously efficient: one word and everyone at the table knows exactly whose mother you mean. Here’s how to say all three, why the maternal words carry the character for outside, and what changes in Cantonese. The wider set is in my grandma names guide.
The two grandmothers, side by side
| Word | Characters | Which grandmother | Rough sound |
|---|---|---|---|
| nǎinai | 奶奶 | father’s mother | NYE-nye |
| lǎolao | 姥姥 | mother’s mother (northern) | LAO-lao |
| wàipó | 外婆 | mother’s mother (southern) | why-PWOR |
奶奶 (nǎinai) doubles a character whose everyday meaning is milk — the same 奶 in the word for milk itself. Reduplicated kinship words like this are all over Mandarin and they read as warm rather than babyish. Third tone, then a light neutral syllable: the first nǎi dips and the second is barely there.
姥姥 (lǎolao) is the northern word, standard in Beijing and across the north, and it’s the one most Mandarin textbooks now lead with. Same shape — third tone plus neutral.
外婆 (wàipó) is the southern word, the default across the Yangtze and south of it. Fourth tone falling, then second tone rising: wài drops, pó climbs.
Families in between use whichever their own mothers used, and a great many overseas Chinese families use both without noticing.
Why the maternal words say “outside”
外 (wài) means outside. It sits at the front of 外婆 and of the formal 外祖母 (wàizǔmǔ), and it is doing exactly what it looks like it’s doing: marking the mother’s mother as belonging to a different family line.
Classical Chinese kinship was patrilineal. A daughter married out; her children belonged to her husband’s line; her own mother was therefore an outside grandmother. The paternal side needs no marker because it was the assumed default — 祖母 (zǔmǔ), the formal written word for grandmother, means the father’s mother unless you put 外 in front of it.
Two things are worth knowing about that. First, it’s the same instinct at work in grandma in Korean, where 외 (oe) marks the maternal grandmother, and in Vietnamese, which uses ngoại — outside — for the same job. These are not coincidences; all three borrowed the character. Second, nobody hears it as a slight in ordinary use. Wàipó is an affectionate word. The etymology is old furniture, and Chinese speakers walk past it the way English speakers walk past the step- in stepmother.
Northern lǎolao sidesteps the whole thing, which is one reason it has spread.
Tones, for a grandmother who wants to get it right
Mandarin tones are not an accent you can skip. They’re part of the word, the way vowel length is in Japanese.
- nǎinai — the first syllable dips down and comes back up (third tone), the second is short and flat.
- lǎolao — same pattern. The vowel is the ow in “cow,” not the ay in “day.”
- wàipó — first syllable falls sharply from high to low, second rises from mid to high, like the end of an English question.
If you’re the non-Chinese grandmother in the family and you’re learning to say the other grandmother’s name, say it slowly. Slow and correct beats quick and flat every time, and everyone can hear you trying.
Cantonese is a different language, not an accent
This trips people up constantly. Cantonese-speaking families — much of Hong Kong, Guangdong, and a great many older Chinatown communities in North America and Britain — use different words, not different pronunciations of the same ones.
The paternal grandmother is 嫲嫲 (màhmā) and the maternal grandmother is 婆婆 (pòhpó). The maternal/paternal split survives intact; the vocabulary doesn’t. So if your grandchild’s other grandmother is Cantonese, do not arrive having practised nǎinai at her.
Great-grandmother, in Mandarin, is commonly 太奶奶 (tài nǎinai) on the father’s side, with 曾祖母 (zēngzǔmǔ) as the formal written form. And the grandfathers pair off exactly as you’d expect: 爷爷 (yéye) on the father’s side, 姥爷 (lǎoye) or 外公 (wàigōng) on the mother’s.
If you’re the American grandmother in a Chinese family
You are not in competition. The Chinese grandmother’s name is decided by which side she’s on and which region she’s from — it isn’t a choice she made, and it isn’t one you can take. Pick your own name freely, and let the two sit together. In the mixed families I taught, the children had a Nǎinai and a Grammy and never once confused them.
What you can do is learn to say hers properly, and use it in front of the grandchildren. It costs one afternoon and it buys a great deal.
Then check with the parents. Their baby, their rules, my cookies.
FAQ: grandma in Chinese
What is grandma in Chinese?
It depends which side. 奶奶 (nǎinai) is the father’s mother; 姥姥 (lǎolao) or 外婆 (wàipó) is the mother’s mother, depending on region.
What is the difference between nai nai and lao lao?
Nǎinai is your dad’s mother and lǎolao is your mom’s. They are different grandmothers, not different words for the same one.
Is it lǎolao or wàipó?
Both mean the mother’s mother. Lǎolao is the northern Mandarin word and wàipó the southern one; families use whichever they grew up with.
Why does wàipó mean “outside grandmother”?
The 外 character marks the mother’s line as outside the father’s family line — a leftover of patrilineal kinship. It is not heard as an insult in everyday speech.
What do Cantonese speakers say?
Màhmā (嫲嫲) for the father’s mother and pòhpó (婆婆) for the mother’s mother. Cantonese is a separate language, so the words differ, not just the pronunciation.
Do other languages split the grandmothers this way?
Yes — grandma in Japanese is the interesting exception that doesn’t, while Korean and Vietnamese both do. The comparison across a dozen languages is in grandma names in different languages.
