Good morning in Vietnamese is chào buổi sáng, said roughly like chow boo-oy sahng. That's the phrase you came for, and here's the part most pages leave out: you'll almost never hear one Vietnamese person say it to another. It exists mainly as a translation of the English phrase rather than as something the language does on its own, and Vietnamese runs no morning, afternoon, evening series at all. Greetings here are indexed to who you're talking to, not what time it is. So this page gives you the phrase, then the thing that actually works: the quick social arithmetic a Vietnamese speaker performs before saying hello, and the handful of words that come out the other side.
Chào Buổi Sáng: The Phrase You Came For, and Why You Won't Hear It
Chào buổi sáng is chào (to greet) plus buổi (a session or period of the day) plus sáng (morning), respelled chow boo-oy sahng. Hanoi pronunciation is transcribed t͡ɕaːw˨˩ ʔɓuəj˧˩ saːŋ˧˦]; Saigon comes out [caːw˨˩ ʔɓuj˨˩˦ ʂaːŋ˦˥]. You'll be understood anywhere in Vietnam. Understood isn't the same as natural, though, and the usage note on the entry is unusually direct: chào buổi sáng is "used as a translation of the English phrase rather than an actual phrase used in Vietnamese proper" ([Wiktionary).
The reason is structural. English organizes greetings on a timeline and lets the clock pick the words. Vietnamese organizes them on a different axis: the age, gender and generation of the person in front of you. Time of day was never encoded, so there's no series to learn, and the greeting you use at breakfast is the one you use at closing time. You'll still meet chào buổi sáng in textbooks, dubbed subtitles, corporate email and as a group address to a room. What you won't get is the woman selling you bánh mì at 7am using it.
⚠️ Don't drill chào buổi sáng and stop there. Nearly every page on this search result hands you the phrase and moves on, which leaves you deploying the one greeting a local wouldn't use. Learn it so you recognize it, then spend your effort on the pronoun system below.
What People Actually Say at Seven in the Morning
Here's the whole answer: chào plus the pronoun that fits the person in front of you. To a man from his teens to about forty, chào anh. To a woman in the same bracket, chào chị. To a teenager or young member of staff, chào em. To someone clearly older than your parents, chào bác. The word chào means "to greet" and it "rarely stands alone," as its dictionary entry puts it, typically requiring a following pronoun or kinship term (Wiktionary). It doubles as goodbye, so the same two words work on the way in and the way out. That same entry explains why xin chào, the greeting most travelers arrive with, sounds slightly off: it's "rather artificial as a greeting" and very common in interface labels, which tells you where it lives. It's still a fine opener for a stranger or a group, and how to say hello in Vietnamese covers the general system in more depth.
For warmth, Vietnamese reaches for a phatic question rather than a time-of-day formula. The best documented one comes from Hanoi fieldwork, where an elderly woman receiving a formal greeting from a child simply nodded and asked Cháu đi đâu đấy?, "where are you going?" (Kien Nguyen, Asian Social Science). It's a greeting, not surveillance, and a vague answer is the correct one. You may also read that people greet each other with Ăn cơm chưa?, "have you eaten rice yet?", which is widely reported rather than dictionary-attested. More on that frame in how to say how are you in Vietnamese.
The Pronoun Table: Who You Are Greeting and What to Call Yourself
Vietnamese pronouns come in reciprocal pairs, which is what makes them hard. Choosing what to call the other person also chooses what you call yourself. Greet a woman as chị and you're em. Greet an elderly man as ông and you're cháu in the north or con in the south. There's no fixed "I" that works with everybody.
| Who You're Greeting | Say | Full Greeting | What You Call Yourself |
|---|---|---|---|
| Anyone clearly younger | em | Chào em | anh (man), chị (woman) |
| A man your age up to about 40 | anh | Chào anh | em, or tôi for distance |
| A woman your age up to about 40 | chị | Chào chị | em, or tôi for distance |
| A man around your parents' age | chú | Chào chú | cháu (north), con (south) |
| A woman around your parents' age | cô | Chào cô | cháu (north), con (south) |
| Older than your parents, either gender | bác | Chào bác | cháu (north), con (south) |
| An elderly man, 60 and up | ông | Chào ông | cháu (north), con (south) |
| An elderly woman, 60 and up | bà | Chào bà | cháu (north), con (south) |
| You genuinely can't judge | xin chào | Xin chào | tôi |
Two rows deserve extra attention. Bác is the traveler's best friend: gender-neutral, and it simply means "senior to my parents," so you can be respectful without picking a gendered term under pressure. And tôi isn't the polite word for "I" that phrasebooks imply. It's the safe one. Politeness research describes it as creating social distance and classes it as non-polite rather than impolite. It won't offend. It will hold a friendly person at arm's length.
⚠️ Men, be careful with em. It's the standard address to anyone clearly younger, and it's also the pronoun a woman uses for herself with her boyfriend or husband, so a man calling a woman of roughly his own age em can read as flirtatious. Use chị for any adult woman who isn't obviously younger. Calling a woman chị when she turns out to be younger is harmless; the reverse is a real error.
Politeness Particles: The Cheapest Upgrade in the Language
Two small words carry a startling amount of weight. Ạ goes at the very end of a sentence directed at someone older and has no English equivalent. It doesn't change what you said, only how respectfully you said it. Dạ does a similar job from the front, marking the whole utterance as deferential. The final ạ is the northern habit; south central and southern speech leans on the initial dạ. Combined with a pronoun pair they produce the deferential formula documented in Hanoi fieldwork: your own pronoun, then chào, then theirs, then the particle. Cháu chào bà ạ! Swap the pronouns to fit: Cháu chào ông ạ, Cháu chào bác ạ.
Be precise about dạ, because most phrasebooks aren't. It isn't a word for "yes." Its dictionary definition is a non-gloss: an initial particle expressing politeness and respect. It attaches to negative answers as readily as positive ones, so Dạ, không is a polite no, not a contradiction. The larger lever, though, isn't a particle. It's using an address term at all, and research finds that omitting one is itself a norm violation. Cảm ơn and cảm ơn chị are different speech acts, which is why how to say thank you in Vietnamese is less about the word than the pronoun attached to it.
Tones and Regions: What Changes Between Hanoi and Ho Chi Minh City
Vietnamese writes six tone categories, and the marks are part of the spelling rather than an optional accent. Drop one and you've written a different word. The classic demonstration stacks all six on one syllable: ma (ghost), mà (but), má (cheek), mả (tomb), mã (code), mạ (rice seedling). You'll see that set glossed elsewhere as ghost, but, mother, tomb, horse, rice seedling, which is looser than it looks. Má is "cheek," with "mother" as a specifically southern sense and mẹ as the standard northern word; mã is "code," the horse sense surviving only bound inside Sino-Vietnamese compounds.
Here's the correction that matters more for a visitor. Southern and central speech has five tones, not six. The hỏi and ngã tones merged in pronunciation across most of the country, leaving northern Vietnamese as the six-tone system and southern as a five-tone one (Bauman et al., University of Maryland CASL). All six diacritics stay in the writing system nationwide, which is why hỏi and ngã spelling mistakes are a familiar literacy problem in Vietnam. Consonants shift too: Hanoi merges d, gi and r into one z sound, so dạ comes out zah, while Saigon keeps them apart and says yah. None of it touches your greeting. Chào anh is the same word everywhere.
⚠️ Say whole phrases, not single words. Adult learners persistently mis-produce the dipping hỏi tone, and context is what rescues a wrong one. A full sentence in a quiet cafe is usually recoverable. An isolated word shouted over traffic, a street name or a number, is where tone stops being optional.
Greeting Customs: Who Speaks First, and Whether to Bow
The strongest rule, and the one visitors miss most, is that the younger person greets first. Informants in Hanoi described it as a moral obligation rather than a nicety, and a young person who waits to be greeted risks being judged vô lễ, discourteous. So if you look younger than the person in front of you, open the greeting. Then expect a smaller response than you gave. A senior may reply with only a nod or a phatic question, and one elderly informant called it "just ridiculous" for him to return a child's formal greeting in kind. That isn't coldness. It's the correct move for their position.
Physically, the head bow is a nod, not a Japanese-style bow from the waist. Cultural guidance describes it as coming from the shoulders and going deeper for higher status (Cultural Atlas). Handshakes between men are normal in urban and business settings, with a two-handed version, your left hand on top, signaling extra respect. Offer rather than insist: Hanoi fieldwork notes rural Vietnamese often aren't used to the gesture. With women, let her offer her hand first, and greet the oldest person in a room before anyone else. If you're asked your age within a minute of meeting, that isn't nosiness. It's the other person working out which row of the table applies, and they can't speak to you correctly until they know.

A Few Parting Notes on Vietnamese Mornings
If you take one thing from this page, make it this: the phrase you searched for is the least useful thing on it. Chào buổi sáng is worth recognizing, and worth having for a group email or a room of people. It isn't what you say to the person handing you a coffee.
Learn six words instead: anh, chị, em, cô, chú, bác. Put chào in front of the one that fits, add ạ if the person is notably older, and you've covered morning, afternoon, evening and goodbye in a single move. Add ơi, because pronoun plus ơi is how you call a waiter over rather than saying "excuse me." A short set of practical lines lives in our essential Vietnamese phrases guide. You'll get pronouns wrong, and nobody minds. The effort registers long before the accuracy does.
