Anh, chị, cô, chú, em — Vietnamese forms of address

What you will learn

Vietnamese forms of address are not a small grammar topic. They are part of how speakers show age, closeness, respect, hierarchy, affection, distance and sometimes anger.

This lesson gives you a practical map. You do not need to start using every form immediately. Some words are important first as things you need to understand when you hear them.

1. Why “I” and “you” are not enough

Vietnamese often chooses words according to the relationship between speakers. “Are you well?” may therefore become Anh khỏe không?, Chị khỏe không?, Em khỏe không?, Cô khỏe không?, Chú khỏe không?, Bác khỏe không?, Ông khỏe không? or Bà khỏe không?.

2. Safe beginner forms to recognize and use

• tôi — neutral first-person pronoun in many contexts
• bạn — friend; also a form of address in suitable contexts
• anh — older brother; commonly used toward a somewhat older male
• chị — older sister; commonly used toward a somewhat older female
• em — younger sibling; commonly used for a younger person
• cô — aunt / female teacher / older woman depending on context
• chú — uncle / older man depending on context
• bác — older-generation adult, depending on relationship and region
• ông — grandfather / older man
• bà — grandmother / older woman
• cháu — younger-generation relationship term toward older adults
• con — child; also a self-reference toward parents and some older/respected figures

3. Relationship pairs matter

• anh – em
• chị – em
• cô – cháu
• chú – cháu
• bác – cháu
• ông – cháu
• bà – cháu
• cha/mẹ – con

The pair tells you how two people position themselves relative to each other.

4. The same word can refer to “I” or “you”

In an anh–em relationship, the older male may refer to himself as anh and the younger person as em. The younger person may refer to themself as em and the older male as anh.

5. A shop conversation

Nhân viên: Chị cần tìm gì ạ?

Khách: Chị muốn xem cái này.

Nhân viên: Dạ, em lấy cho chị nhé.

Khách: Cảm ơn em.

Nhân viên: Dạ, không có gì ạ.

6. Ông and bà mean more than grandfather and grandmother

Ông and bà are family words, but they can also address older people outside the family.

• Ông tôi. — My grandfather.
• Bà tôi. — My grandmother.
• Cháu chào ông ạ. — Respectful greeting to an older man.
• Cháu chào bà ạ. — Respectful greeting to an older woman.

You may also encounter ông ấy and bà ấy when referring to a third person.

Among adults, ông – tôi or bà – tôi may also appear in familiar, joking, mildly complaining or other context-dependent speech. They do not always literally mean “grandfather” or “grandmother”.

7. Mình — a flexible relationship word

Mình may refer to the speaker, to both people as “we”, or even be used for the other person in a close relationship.

• Mình tên là Lan. — I’m Lan, in a suitable friendly context.
• Mình đi nhé. — Let’s go / I’m going, depending on context.

8. Cậu and tớ

Cậu – tớ is a familiar pair often heard among friends or classmates in suitable contexts.

• Cậu đi đâu đấy? — Where are you going?
• Tớ đi ăn. — I’m going to eat.

It is not a universal “you–I” pair. Region, generation and personal style matter.

9. Tao and mày: understand before you use

Tao – mày is essential to understand because learners may hear it in films, among friends, in families, online and during arguments.

It cannot safely be translated as simply “I – you”. Its social meaning changes dramatically with the relationship.

Between close friends

Some very close friends use tao – mày naturally. In that relationship it may signal intimacy, equality and informality rather than hostility.

Tao gọi mày tối nay nhé. — I’ll call you tonight.

During an argument

The same pair can sound aggressive or insulting during conflict. A sudden switch from polite or neutral address to tao – mày can itself show that the emotional relationship has changed.

In families and local speech

You may hear these words in some family relationships, between adults and children, or in regional/community speech. Their force depends heavily on who is speaking to whom and how.

A beginner safety rule

Understand it before you use it.

Beginners should learn to recognize tao – mày, but should not copy it simply because friends, films or videos use it. With the wrong person it can sound rude, disrespectful or openly hostile.

10. Relationship can change inside one conversation

Forms of address can change when a relationship changes. Two people may become more familiar, or an argument may make one speaker deliberately choose a harsher form. Pronoun choice can therefore carry emotional information that an English translation hides.

11. Useful vocabulary and concepts

• xưng hô — forms of address
• tôi, bạn — common neutral/basic forms
• anh, chị, em — common relationship terms
• cô, chú, bác — older-generation relationship terms
• ông, bà — grandparent terms / older-person address
• cháu, con — younger-generation relationship terms
• mình — flexible self/relationship word
• cậu, tớ — familiar pair in suitable contexts
• tao, mày — strongly relationship-dependent informal pair
• lịch sự — polite
• thân mật — familiar / intimate
• thô — coarse / rude, depending on context
• tôn trọng — respect

12. Common beginner mistakes

• Translating every English “you” as bạn.
• Thinking a Vietnamese address word has only one fixed pronoun meaning.
• Choosing someone’s age category too confidently from appearance alone.
• Copying tao – mày without understanding the relationship.
• Assuming a family word is only used with biological relatives.

13. Vietnam in real life

Vietnamese address terms reflect age, relationship and social position. Modern life changes usage in many settings, but the relationship system remains central to everyday speech.

There is no single perfect rule for the whole country. Region, family, generation, workplace and personal style all matter.

Try it

1. Build “Thank you” in an anh–em relationship.
2. Say a respectful greeting using cháu – bà.
3. Explain why tao – mày cannot be translated simply as “I – you”.
4. Listen to a conversation and identify the relationship pair.
5. Notice whether that pair changes during the conversation.

Quick recap

Vietnamese forms of address are a relationship system. Beginner-safe forms include tôi, bạn, anh, chị, em, cô, chú, bác, ông, bà, cháu and con. Flexible forms such as mình and cậu–tớ need context. Tao–mày is important to understand but should be used only when the relationship and social meaning are clear.
