Nó is a common third-person singular form for things and animals. It can also refer to a person, especially a child, a younger family member, or an intimate peer—but then it carries information about age, status, closeness, and stance. It has no grammatical gender: depending on context, nó can correspond to English it, he, or she.
That last fact does not make nó a universal gender-neutral person pronoun. English chooses he or she mainly by gender and uses it mainly for nonhumans. Vietnamese often chooses among nó, a name, a kinship term, and combinations such as anh ấy or chị ấy according to the relationship between speaker, referent, and listener.
The core reference map
| Referent | Use of nó | Likely alternative |
|---|---|---|
| Object or previously mentioned thing | Ordinary when an explicit pronoun is useful | Zero reference or repeat the noun |
| Animal | Ordinary; may be affectionate or matter-of-fact | Pet’s name |
| Child or much younger family member | Common from an older speaker | con, cháu, em, name |
| Close equal peer | Informal in some in-groups | Name, bạn ấy, anh ấy, chị ấy |
| Respected adult, elder, customer, or senior | Often dismissive or disrespectful | Title, kinship term, name + title |
The form refers to someone or something outside the speaker–addressee pair. It is not normally a second-person address term. Its social force comes from how the speaker positions that third person.
Things and animals
For an inanimate referent, nó is an ordinary “it.” Vietnamese nevertheless omits a recoverable object pronoun more often than English, so explicit nó is used when it helps maintain, contrast, or personify the topic.
Cái máy này cũ rồi nhưng nó vẫn chạy tốt.
This machine is old, but it still runs well.
Tôi để chìa khóa trên bàn mà giờ không thấy nó đâu.
I left the key on the table, but now I can't find it anywhere.
With animals, nó is equally common and does not specify sex:
Con mèo trốn dưới gầm giường; chắc nó sợ tiếng sấm.
The cat is hiding under the bed; it must be afraid of the thunder.
Bông đói rồi đấy, em cho nó ăn chưa?
Bông is hungry—have you fed her yet?
English calls the pet “her,” but Vietnamese nó remains ungendered. Using the pet’s name can add affection or clarity; nó itself is not necessarily cold.
Children and younger people
Adults commonly use nó for their own child, a younger relative, or another clearly younger person under discussion. In such relationships the form can be ordinary or affectionate rather than contemptuous.
Con bé ngủ rồi, mai nó còn phải đi học sớm.
The little girl is asleep; she has to go to school early tomorrow.
Thằng út nhà tôi mê bóng đá lắm; tối nào nó cũng ra sân.
My youngest boy loves football; he goes to the field every evening.
The colloquial classifiers con bé “the little girl” and thằng út “the youngest boy” establish a downward age perspective. Their appropriateness depends on who is speaking. A stranger or younger speaker copying the same wording can sound presumptuous.
A younger participant should not infer that an older person’s use of nó is reciprocal. If an aunt refers to her nephew as nó, the nephew still refers to the aunt as cô, not nó.
Cô gọi cháu à? Cháu đang ở ngoài cổng.
Did you call me, auntie? I'm outside the gate.
The pair cô–cháu represents the younger speaker’s side of the relationship. Vietnamese person reference is perspectival and relational rather than a permanent label attached to one person.
Intimate peers and hostile stance
Some close friends use nó for an absent member of their group. In that in-group setting it may convey easy familiarity:
Nó bảo sẽ đến muộn một chút, mình cứ gọi món trước đi.
He says he'll be a little late; let's go ahead and order.
This is natural only if the speaker is entitled to place Nam inside that intimate peer frame. The same nó used about a senior colleague, customer, or respected elder can sound belittling. A speaker may also choose it deliberately to express contempt during conflict.
Anh Hùng gọi rồi. Anh ấy muốn đổi giờ họp.
Hùng called. He wants to change the meeting time.
Anh ấy treats Hùng as an older male peer or as someone accorded that relationship. Replacing it with nó would lower him socially or imply a close in-group license.
The distinction is not simply “human versus nonhuman.” It is better understood as a person-and-stance scale: nó is structurally available for humans, but respectful human reference often calls for a name, role, or relational expression.
Names, relational terms, and ấy
Vietnamese has many respectful or socially informative third-person alternatives:
| Form | Typical reference | Social information |
|---|---|---|
| anh ấy | he / that older male peer | male, somewhat older or respectfully classified |
| chị ấy | she / that older female peer | female, somewhat older or respectfully classified |
| em ấy | that younger person | younger peer-generation referent |
| cô ấy | she / that woman | female reference; age and regional range vary, so it is not simply “older-generation she” |
| chú ấy | he / that uncle-age man | male reference and typically a senior-generation relationship |
| name or title | the named person | maximal clarity; role can be preserved |
| nó | it / the animal / the younger or intimate person | no gender; informal/downward stance with people |
Ấy helps make a kinship term third-person: anh can mean “I” or “you” inside an anh–em relationship, while anh ấy clearly points to a third person. Repeating a name is also natural where English strongly prefers a pronoun.
Chị Lan nói chị ấy sẽ đến sau.
Lan said she would come later.
In context, speakers might simply say Chị Lan nói sẽ đến sau, omitting the embedded subject because Lan remains understood. Zero reference is often the least socially risky option when it is clear.
The wider person-reference system
The following minimal contrast shows why nó cannot be learned in isolation:
- tôi, tớ, mình: different first-person stances, from relatively neutral to friendly;
- bạn: peer or generalized second person, with important limits;
- anh, chị, em, cô, chú: relationship terms usable for speaker, addressee, or third person depending on context;
- chúng ta: inclusive “we,” including the addressee;
- chúng tôi: exclusive “we,” normally excluding the addressee;
- nó: third-person singular for things and animals, and socially restricted person reference.
English person pronouns primarily separate speaker, listener, and others, with gender in the third person. Vietnamese adds age, role, intimacy, inclusivity, and stance. This is grammar as well as etiquette because these choices determine ordinary reference and the interpretation of an utterance.
A dialogue where the referent changes the force
— Nó đến chưa? — Con chó ấy à? Nó đang ngoài sân.
— Has it arrived? — You mean that dog? It's in the yard.
Here nó is unremarkable. Now put the same question in a workplace:
— Giám đốc đến chưa? — Ông ấy đang ở phòng họp ạ.
— Has the director arrived? — He's in the meeting room.
Answering Nó đang ở phòng họp would normally sound disrespectful toward the director. The human referent’s status changes the socially appropriate form even though the truth conditions remain the same.

Common Mistakes
1. Using nó as the default “he/she” for a respected adult
❌ Bác sĩ Lan gọi rồi; nó muốn gặp chị sáng mai.
Incorrect or insulting: nó lowers a respected adult who has not been framed as an intimate peer.
✅ Bác sĩ Lan gọi rồi; chị ấy muốn gặp chị sáng mai.
Dr. Lan called; she wants to see you tomorrow morning.
The repair preserves respectful human reference with chị ấy. Repeating bác sĩ Lan would be even clearer if several women are involved.
2. Assuming nó means male
❌ Nó ngủ rồi.
Incorrectly translated without context as “He is asleep”: nó carries no masculine gender.
✅ Con bé ngủ rồi; nó mệt lắm.
The little girl is asleep; she's very tired.
The noun phrase con bé supplies female reference; nó merely continues that referent.
3. Copying an elder’s form from the wrong side of the relationship
❌ Bà mệt nên nó nghỉ đi.
Incorrect when a younger speaker means grandmother: nó treats her downward.
✅ Bà mệt thì bà nghỉ đi ạ.
If you're tired, Grandma, please rest.
The younger speaker repeats bà and adds ạ. The fact that the grandmother may use nó for the grandchild does not authorize the reverse.
4. Using singular nó for a plural group
❌ Mai và Lan đâu? Nó về rồi.
Incorrect for “They went home”: nó is singular.
✅ Mai và Lan đâu? Hai bạn ấy về rồi.
Where are Mai and Lan? Those two went home.
The explicit phrase hai bạn ấy preserves plural reference without deciding between more formal and more colloquial plural pronouns. The broader choice among plural forms belongs on the following page.
Key Takeaways
- Nó is ungendered third-person singular: it may translate as “it,” “he,” or “she.”
- It is ordinary for things and animals and common for children or clearly younger people from an older perspective.
- With adult people, it can signal intimate in-group membership, downward hierarchy, dismissal, or hostility.
- Use names, titles, anh ấy, chị ấy, em ấy, cô ấy, or chú ấy for clearer or more respectful person reference.
- A form used downward by an elder is not automatically available upward to a younger speaker.
