Every guide to hello in Vietnamese opens with xin chào, and none of them are lying to you. It's correct, it's understood everywhere in the country, and nobody will think less of you for using it. It's also not what Vietnamese people say to each other. The everyday greeting is chào plus a word that places the person in front of you, usually by age and sometimes by gender. Get that word right and a shopkeeper's face changes. Get it wrong and you've either demoted an elderly woman to a teenager or flirted with somebody's wife. So this post teaches the word, not just the greeting, because the word is the part that's actually a skill.
Xin Chào and Chào: The One You're Taught and the One You'll Hear
Xin chào is pronounced roughly "sin chow," from xin, meaning to beg or request, plus chào, meaning to greet. Every Vietnamese speaker alive understands it and it's never wrong from a visitor. It is also, in Wiktionary's words, "rather artificial as a greeting and often used as a direct translation of hello," and "very common in interface labels" (Wiktionary). That's where you'll meet it: airport signage, website headers, a guide addressing a coach full of strangers. It's a greeting for a room, not for a person.
Chào is the bare verb, and it almost never stands alone. It wants a pronoun after it, and that following word is the whole game. Chào anh to a man around your age, chào chị to a woman, chào em to a teenager or a young waiter. Same verb, three different social moves, and it doubles as goodbye. At full strength the greeting has four parts, documented in Hanoi fieldwork as your pronoun, chào, their pronoun, then a polite particle: Cháu chào bà ạ. That study found that for a younger speaker, "failing to address these personal pronouns, a greeting of inferiors can be regarded as impolite" (Nguyen, Asian Social Science).
Two footnotes. On the phone the default greeting is a-lô, not xin chào. And there's no morning, afternoon, evening series to learn: chào buổi sáng translates the English phrase rather than a Vietnamese habit, which we've pulled apart in good morning in Vietnamese. Greetings here are indexed to who you're talking to, not to the clock.
The Pronoun Table: Who You Greet and What You Call Yourself
Here's the part phrasebooks skip. Vietnamese address terms are borrowed from the family: older brother, older sister, aunt, uncle, grandmother. They come in reciprocal pairs, so with the single exception of tôi, picking what you call the other person also picks what you call yourself. The decision rule is two questions: are they older or younger than you, and are they your generation, your parents' generation, or older?
| Who You're Greeting | Call Them | Literally | Call Yourself |
|---|---|---|---|
| Child, teenager, young cafe staff | em | younger sibling | anh (man) or chị (woman) |
| Man, teens to about 40 | anh | older brother | em, or tôi for distance |
| Woman, teens to about 40 | chị | older sister | em, or tôi for distance |
| Man around your parents' age | chú | father's younger brother | cháu (north) or con (south) |
| Woman around your parents' age | cô | father's sister | cháu (north) or con (south) |
| Anyone older than your parents | bác | senior to your parents | cháu (north) or con (south) |
| Elderly man, roughly 60 up | ông | grandfather | cháu (north) or con (south) |
| Elderly woman, roughly 60 up | bà | grandmother | cháu (north) or con (south) |
| A group, or nobody you can place | no pronoun, xin chào | beg plus greet | tôi |
Bác is the most useful row there. It's gender-neutral and means, roughly, senior to my parents, so you can be respectful without calling the gendered terms correctly. Guessing somebody too senior is flattering; guessing them too junior is not.
⚠️ Be careful with em, especially if you're a man. Em is also what a woman calls herself with her boyfriend or husband, so a man calling a woman of roughly his own age em can read as flirtatious rather than friendly. Use chị for any adult woman who isn't clearly younger than you.
Two corrections to finish. Tôi is the safe word, not the polite one: Le's research on Vietnamese politeness is blunt that it isn't a polite reference form at all and that it creates social distance. Not impolite, just cool. Fine with a stranger, chilly with somebody being warm to you. And skip bạn, whatever your app taught you. It means friend, and it's the generic "you" of writing and app interfaces, but said to somebody visibly older it lands as textbook-ish. One last thing: if a stranger asks your age a minute after meeting you, that isn't nosiness. They're working out which row applies.
Dạ and Ạ: The Two Syllables That Do the Most Work
Once you can pick a pronoun, two tiny particles do more for you than another fifty words of vocabulary. Ạ goes on the end, marking politeness toward somebody older. Chào bác and Chào bác ạ say the same thing, and the second says it respectfully. Dạ goes on the front, and it is not the word for yes, however many phrasebooks say so. It's a particle marking politeness and respect, carrying no meaning of its own, which is why it attaches to negative answers as readily as positive ones. Dạ, không is a polite no, not a contradiction.
The regional split is worth carrying. In the north, ạ closes the sentence and vâng is the compliant yes; in the center and south, dạ does the work at the front. We've taken that pair apart in yes and no in Vietnamese. Then there's ơi, which earns its keep in every restaurant you enter. Pronoun plus ơi is how you call somebody over: em ơi to young staff, anh ơi or chị ơi to anyone older. Waving, or shouting xin lỗi across a room, is what foreigners do. The same logic runs through thanks, and thank you in Vietnamese covers why cảm ơn chị beats a bare cảm ơn.
The Six Tones: What a Traveler Actually Needs
Vietnamese spelling encodes six tones, and the standard demonstration runs one syllable, ma, through all of them. This is the paradigm used in Kirby's description of Hanoi Vietnamese for the Journal of the International Phonetic Association (Illustrations of the IPA):
- ma, no mark at all, mid level: ghost. The absence of a diacritic is itself a tone.
- mà, grave accent, low falling: but.
- má, acute accent, rising: cheek.
- mả, hook above, dipping then rising: tomb. The hardest one for English speakers.
- mã, tilde, rising with a creak in the middle: code.
- mạ, dot below the vowel, short and cut off: rice seedling.
⚠️ The version of that list you've seen elsewhere is probably mis-glossed. The popular set translates má as "mother" and mã as "horse." Má is "cheek," and the mother sense is specifically southern, where the northern standard word is mẹ. Mã is "code," and the horse sense survives inside compounds rather than as a free word.
The greeting-relevant case is bà against ba: grandmother, and the number three. One tone apart, and audible. The count isn't fixed either. Northern Vietnamese runs six tones, but southern and central speech merges hỏi and ngã into one, giving five across most of the country's spoken varieties (Bauman et al., University of Maryland). All six diacritics stay in the writing system nationwide.
How much does accuracy matter? Less than the scare stories claim, and more than you'd like. A wrong tone inside a full sentence in a quiet cafe is usually recoverable, because context does the work. A wrong tone on a single word shouted over traffic, a street name to a driver, often isn't. So say whole phrases rather than bare words, and write numbers and place names down. Don't believe anyone who says locals won't notice. They recover, which is not the same thing.
North and South: Why Hanoi and Saigon Sound Different
The first time you hear a Hanoi speaker and a Saigon speaker say the same word, you'll wonder whether your phrasebook was printed for another country. The biggest difference is what happens to the letters d, gi and r. In Hanoi they've collapsed into one "z" sound, so dạ comes out as "zah." In the south they stay apart, with d and gi becoming a "y" and r a genuinely distinct sound. That same dạ is "yah" in Ho Chi Minh City.
Which surprises people, because Hanoi turns out to be the merging dialect rather than the conservative one. Northern speech also collapses tr into ch and s into x, so "ra," "da" and "gia" are homophones there, while southern speech keeps those apart and sits closer to the spelling. Neither is correct: standard references recognize two spoken standards and prefer neither, though Hanoi underpins the written norm. Vocabulary differs too, vâng in the north against dạ in the south. Learn the variety of the region you're in.
Bowing, Handshakes, and Who Greets First
The rule visitors miss most has nothing to do with words. In Vietnam the younger person greets first, and it's an obligation rather than a nicety. In Nguyen's Hanoi interviews, a young person who lets an elder greet first is judged discourteous, and one elderly informant said flatly that he should never greet such a person first. If you look younger than whoever is in front of you, open the greeting.
⚠️ Don't read a short response as a snub. Greetings here are asymmetric by design. A senior may answer your careful greeting with nothing more than a nod, or by asking where you're going. One elderly informant called it "just ridiculous" to return a child's formal greeting in kind. That isn't coldness, it's the correct move for their position.
The physical side is smaller than most guides make it sound. Bow the head slightly, from the shoulders, deeper for someone of higher status. It's a nod, not a Japanese-style bow from the waist (Cultural Atlas). Handshakes are normal, particularly between men and in urban settings, and putting your left hand on top signals extra respect. Offer rather than insist, because rural Vietnamese are often not used to it. With women, let her offer her hand first. Hugging is for close relationships only, and walking into a family room, greet the oldest person first. Our guide to Vietnam etiquette dos and donts covers the rest of the room.
A Few Parting Notes on Getting It Wrong
You will get it wrong, and so does everyone. Nguyen quotes an Australian who had lived in Vietnam for years and still got caught out in groups of three or more, because he had to call himself anh with one person, cháu with another and con with a third in the same conversation. Politeness here is a live calculation, not a register you switch on. Informants in that study kept quoting the proverb Lời chào cao hơn mâm cỗ, a greeting is worth more than a feast.
So don't over-engineer it. Start at xin chào with a smile, which beats silence. Move to chào anh or chào chị as soon as you can judge who's in front of you. Add ạ when the person is older. Three words, chào, ơi and ạ, will carry most encounters in a market or a hotel lobby, and essential Vietnamese phrases fills the gaps. To get past hello into small talk, how are you in Vietnamese explains why the textbook question isn't the one people ask. One practical note before you go: none of this touches your paperwork, but the entry point you name on your eVisa application has to be the one you turn up at.
