How are you in Vietnamese is Bạn khỏe không?, with khỏe không said roughly khwe khohm. That's the phrase every textbook hands you, and it's perfectly grammatical. It's also, on an ordinary Vietnamese street, close to the wrong tool. English "how are you" is a formality nobody expects a real answer to. The Vietnamese question is an actual enquiry after someone's health, aimed at a person you already know, and fired at a stranger it lands as oddly personal. The openers Vietnamese genuinely runs on are different, and the most useful of them translates as "have you eaten rice yet?". So this page gives you the phrase you came for, flags the one word in it that most guides get wrong, and then hands you what people say instead, plus how to answer.
Khỏe Không: The Phrase You Searched For, and What It Actually Asks
The full frame is có khỏe không, literally "have + healthy + not", built the standard Vietnamese way: subject, then có, then the thing asked about, then không at the end. The dictionary's own example for that frame is Anh có khỏe không? (Wiktionary). In speech the có is optional and usually dropped, leaving Khỏe không?, khwe khohm, the version you'll actually meet.
Here's the part competing pages skip. That question is a real enquiry, not a verbal handshake. Ask it of a colleague you haven't seen in months, or a neighbor recovering from something. Ask it of the woman selling you coffee and you've asked a stranger about her health. Cultural guidance on Vietnamese greetings makes the structural point plainly: Khỏe không? typically follows an opening greeting rather than replacing it (Cultural Atlas). It's the second thing you say, not the first.
There are contexts where it's exactly right: a language class, a formal or teaching setting, any moment when you genuinely want to know how someone is. Used that way it isn't textbook at all. It's just a question.
⚠️ The phrase you searched for isn't the phrase you'll hear. Nearly every page ranking for this query hands you Bạn khỏe không? and stops, which leaves you deploying an earnest health question as small talk. Learn it so you recognize it, then spend the rest of your effort on the two sections below.
The Pronoun Problem: Bạn Is Rarely the Right Word for a Stranger
Bạn literally means "friend". It works peer to peer among people in their teens and twenties, and it's the generic "you" of writing, broadcasting and app interfaces, which is exactly why it ends up in every phrasebook. It is not an all-purpose second person. Said to someone visibly older, it lands as textbook-ish at best and faintly presumptuous at worst.
The fix is the one that governs every greeting in the language. Pick the address term that places the person relative to you, and use that instead. To a man from his teens to about forty, Anh khỏe không? To a woman in the same bracket, Chị khỏe không? To a teenager or a young member of staff, Em khỏe không? For anyone clearly senior to your own parents, bác is the traveler's safety net, because it's gender neutral and simply means "older than my parents".
These terms come in reciprocal pairs, which is the hard part: choosing what to call someone also chooses what you call yourself. Call a woman chị and you're em. Call an elderly man ông and you're cháu in the north or con in the south. The full table lives in our guide to how to say hello in Vietnamese, and it's the highest-value thing on any of these pages.
Ăn Cơm Chưa: The Opener That Does the Work Instead
If English "how are you" has a functional counterpart in Vietnamese, it's Ăn cơm chưa?, an kuhm chuh-uh, literally "eat + rice + yet?". It is not a question about food. Nobody is offering you lunch. It's a phatic opener between people who already know each other, and the expected response is a Rồi or a nod, after which the conversation moves on. Ăn cơm is glossed in the dictionary as "to eat food; to have a meal" (Wiktionary), and asking whether someone has eaten is asking whether they're all right.
The better documented sibling is Đi đâu đấy?, dee doh day, "where are you going?", which shows up in peer-reviewed Hanoi fieldwork: an elderly woman who's just received a formal greeting from a child nods and asks Cháu đi đâu đấy? (Kien Nguyen, Asian Social Science). It's a greeting, not surveillance, and a vague answer is the correct answer. Southern speakers say Đi đâu đó?.
Both belong to one pattern, and the pattern matters more than either phrase: Vietnamese small talk opens with something concrete about your day rather than an abstract question about your state. The same instinct explains why there's no morning or evening greeting series to memorize, which how to say good morning in Vietnamese takes apart in full.
⚠️ Treat Ăn cơm chưa as reported rather than dictionary-attested. The words and their tone marks are verified, but the dictionary carries no usage note calling the expression a greeting, and its phatic function turns up in popular and language-learning sources rather than academic ones. It's real and you'll hear it. We flag it because a page presenting it as a documented set phrase is claiming more than the sourcing supports.
The Openers You Will Hear, and How to Answer Each One
Five lines cover almost everything a visitor meets in the first week. Note how few are questions in any meaningful sense, and how short the correct answers are.
| What They Say | What It Literally Means | When It's Used | How to Answer |
|---|---|---|---|
| Chào anh / Chào chị | greet + older brother or sister | The all-purpose opener, any time of day | Chào anh, or Chào chị, back |
| Khỏe không? | healthy + not? | A genuine health question, to someone known | Khỏe, or Bình thường |
| Anh khỏe không? | older brother + healthy + not? | The same, with the pronoun that fits the person | Khỏe |
| Ăn cơm chưa? | eat + rice + yet? | Reported as the everyday opener between acquaintances | Rồi, or Chưa |
| Đi đâu đấy? | go + where + there? | Documented as an elder's greeting to a younger person | Anything vague. It isn't really a question |
Khỏe on its own is the straight answer to khỏe không. Bình thường, roughly "normal", is the honest neutral one, and it's a more natural thing to say than the relentless "great, thanks" an English speaker defaults to. Neither needs a full sentence built around it. Vietnamese doesn't expect one.
Answering Back: Echo the Question Instead of Saying Yes
The most reliable trick in the language is the echo answer. To say yes, repeat the verb or adjective from the question. To say no, put không in front of it. Asked Khỏe không?, you answer Khỏe. Asked Đói không? ("hungry?"), you answer Đói, or Không đói. That's what native speakers do by default, and it sidesteps the tangle of Vietnamese words that get translated "yes" without meaning it.
That tangle is worth knowing in summary. Có is the factual yes, the one that pairs with the có...không frame. Vâng and dạ are politeness markers rather than affirmations, and dạ attaches to negative answers as readily as positive ones, so Dạ, không is a polite no rather than a contradiction (Le, Victoria University). The full system, including why a Vietnamese "yes" is sometimes deference rather than agreement, is laid out in how to say yes and no in Vietnamese.
⚠️ A question ending in chưa never takes có or không. Those run on a different axis, completed or not completed, so they're answered Rồi (already) or Chưa (not yet). Answer Ăn cơm chưa? with Có and you've marked yourself as a learner in one syllable. Answer Rồi and you've closed the exchange the way a local would.
Dạ and Ạ: Two Syllables That Change Your Register
Two tiny words carry a startling share of Vietnamese politeness, and both cost you nothing. Ạ goes on the very end of a sentence directed at someone older, and has no English equivalent. It doesn't change your meaning, only how respectfully the meaning arrives. Dạ does a comparable job from the front, marking the whole utterance as deferential. Politeness research describes dạ as not communicative by itself, serving instead as a polite answer, closer in function to English "please" than to "yes".
The practical version is simple. Ask Bác khỏe không ạ? rather than Bác khỏe không? and you've raised the register by one syllable. Answer an elder Dạ, khỏe rather than bare Khỏe and you've done the same from the other end. The final ạ is the northern habit; south central and southern speech leans on the initial dạ.
The larger lever isn't a particle at all. It's using an address term in the first place, and research finds that omitting one is itself a norm violation with a senior. That's why bare cảm ơn is a weaker speech act than cảm ơn chị, and why how to say thank you in Vietnamese is mostly about the pronoun attached to it.
North and South: What Changes Between Hanoi and Ho Chi Minh City
The good news first: khỏe không is the same in Hanoi, Hue and Ho Chi Minh City. No word swaps, no regional alternative to memorize. What shifts is the sound around it. Hanoi merges d, gi and r into a single z, so dạ comes out zah and rồi comes out zoy. Saigon keeps them apart and says yah and roy, with a genuinely rolled or retroflex r. Southern speakers also shorten không, so a "no" that sounds like hông is the same word.
One correction is worth carrying, because plenty of pages get it backward. 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 errors are a familiar literacy problem in Vietnam.
The classic tone demonstration is glossed loosely too. The set is ma, mà, má, mả, mã, mạ, usually rendered as ghost, but, mother, tomb, horse, rice seedling. More precisely, má is "cheek", with "mother" a specifically southern sense, and mã is "code", the horse reading surviving only bound inside Sino-Vietnamese compounds. One spelling note, since you'll meet both: khỏe and khoẻ are equally correct.
A Few Parting Notes on Asking After People
The honest summary of this page is that the phrase you searched for is the least useful thing on it. Bạn khỏe không? is worth recognizing, worth using when you actually want to know how someone is, and worth dropping the bạn from. What replaces it isn't another phrase to memorize. It's a habit: greet with chào plus the right term, then, if you want warmth, ask something concrete about their day.
Get the pronouns wrong and nobody minds. Vietnamese speakers watch foreigners attempt this constantly, and the effort registers long before the accuracy does. What does read as odd is a stranger opening with an earnest question about your health. Other lines worth having on arrival sit in our essential Vietnamese phrases guide.
