Basic Commands and Requests in Vietnamese

In Brief

Vietnamese normally forms a command without changing the verb: Ngồi xuống! means “Sit down!” Add đừng for “don’t,” and choose words such as xin, làm ơn, hãy, or the sentence-final particles nhé and đi to adjust politeness and tone. The form of the verb stays the same; context and the way you address the listener do much of the social work.

Overview

Commands tell someone to do something; requests ask them to do it. Vietnamese uses the same unchanged verb in both, then relies on optional markers, sentence-final particles, voice, and context to show whether the speaker sounds firm, encouraging, or polite. An imperative (a command form) can therefore be as short as Đi! (“Go!”), but most real conversations provide more context.

This is an A1 topic because the beginner pattern is simple: use the verb or verb phrase directly, use đừng + verb for a negative command, and add a suitable softener for a request. Unlike English, Vietnamese does not need a special form such as go versus goes, and it does not require do in a negative command. The verb ngồi remains ngồi in Ngồi đi, Hãy ngồi, and Đừng ngồi đây.

The challenge is social rather than morphological. Vietnamese address words often identify a relationship—older sibling, younger person, customer, teacher, and so on. A grammatically correct request can still sound abrupt if the address term or particle does not fit the situation. Beginners should first learn neutral, useful patterns and listen carefully to how speakers around them address one another.

How It Works

1. The basic pattern: verb first

The listener is usually understood, so a command can begin directly with a verb:

(address term) + verb + object/complement

• Đứng lên. — Stand up.
• Mở cửa. — Open the door.
• Anh vào đi. — Come in. (addressing an appropriate male as anh)

An address term is the word used for the person you are speaking to. Vietnamese often uses kinship-style words such as anh, chị, em, cô, and chú where English simply uses “you.” Their correct choice depends on age, relationship, and setting. You can omit one when the listener is obvious, but including the right one may make the interaction warmer and clearer.

Bare commands are common when urgency, authority, or a close relationship makes the intention obvious. They are also natural in short instructions. With a stranger, however, a bare Đợi! (“Wait!”) may sound sharper than English “Please wait.” Use a softening pattern when politeness matters.

2. Positive markers and softeners

Vietnamese has several ways to frame the action. They overlap, but they are not interchangeable versions of English please.

Pattern	Main effect	Typical use	Example
verb	direct instruction	urgent situations, close relationships, clear procedures	Dừng lại! — Stop!
hãy + verb	urging or instructing someone to act	advice, instructions, speeches, writing	Hãy nghe kỹ. — Listen carefully.
xin + verb	polite or formal request	announcements, notices, customer-facing language	Xin chờ một chút. — Please wait a moment.
làm ơn + verb	explicit request for a favor	everyday requests; often followed by giúp or được không?	Làm ơn nói chậm. — Please speak slowly.
vui lòng + verb	courteous institutional request	signs, forms, service instructions	Vui lòng xếp hàng. — Please queue.

Hãy often presents an action as something the listener should do. In a lesson, written instruction, public appeal, or piece of advice, it can sound natural and clear. It does not automatically make a personal request courteous. Hãy đưa tôi cái đó can sound like an instruction, not a gentle “Could you pass me that?”

Xin before a verb gives a polite, often somewhat formal request: Xin đợi or Xin mời vào. In conversation, xin is also part of fixed courteous expressions such as xin lỗi (“sorry/excuse me”). Vui lòng is especially common in public notices and service language; it may sound institutional between close friends.

3. Negative commands with đừng

For “don’t do X,” put đừng before the verb phrase:

(address term) + đừng + verb + object/complement

• Đừng lo. — Don’t worry.
• Đừng mở cửa. — Don’t open the door.
• Em đừng đi vội. — Don’t leave in a hurry.

Do not add an English-style auxiliary equivalent to do. Đừng itself marks the negative instruction. A final nhé can turn a prohibition into a gentler reminder: Đừng quên nhé (“Don’t forget, okay?”).

For a firm rule or prohibition, Vietnamese also uses không được + verb, literally expressing that an action is not allowed:

• Không được hút thuốc. — No smoking / You must not smoke.
• Không được chạm vào. — Do not touch it.

This is stronger and more rule-like than ordinary đừng. At A1, use đừng for everyday negative requests and recognize không được on signs or in firm warnings.

4. Sentence-final nhé and đi

Vietnamese uses sentence-final particles—small words at the end that show the speaker’s attitude or manage the relationship with the listener. They usually do not translate word for word.

• nhé seeks cooperation, confirms shared understanding, or makes a reminder warmer: Chờ tôi nhé. — Wait for me, okay?
• đi urges the listener to proceed and can make an invitation or encouragement sound more conversational: Ăn đi. — Go ahead and eat.

Tone and context remain important. Đi! by itself is the verb “go” and can be a sharp command. In Ăn đi, final đi is a particle encouraging the action. Position tells you which role it has.

A common beginner-safe contrast is:

Form	Likely force
Ngồi xuống.	Sit down. Direct and neutral-to-firm, depending on tone.
Hãy ngồi xuống.	Do sit down / Please sit down. Instructive or encouraging.
Ngồi xuống nhé.	Sit down, okay? Cooperative and softer.
Ngồi xuống đi.	Go ahead and sit down. Encouraging or urging.
Xin mời ngồi.	Please have a seat. Courteous and conventional.

5. Requests with cho tôi and questions

Cho + person + verb can ask for permission or an opportunity to act. With tôi (“I/me”), Cho tôi xem means “Let me see” or, depending on context, “Show it to me.” The object can make the meaning clearer:

• Cho tôi xem thực đơn. — Let me see the menu.
• Cho tôi hỏi một câu. — Let me ask a question.
• Cho em vào nhé. — Let me come in, okay? (speaker refers to themself as em)

Vietnamese also makes polite requests as questions. được không? means roughly “is that possible/okay?” and gives the listener an explicit choice:

• Bạn nói chậm một chút được không? — Could you speak a little more slowly?
• Cho tôi xem cái này được không? — Could you let me see this?

Adding giúp (“help”) presents an action as help done for someone: Mở cửa giúp tôi nhé (“Please open the door for me”). This is often more natural than trying to attach one universal translation of English please.

Common Mistakes

Treating hãy as a universal translation of “please”

• Awkward in many personal requests: Hãy đưa tôi thực đơn.
• More natural: Cho tôi xem thực đơn được không? / Làm ơn đưa tôi thực đơn.
• Why: hãy commonly introduces advice, an appeal, or an instruction. Politeness comes from the whole construction, not from replacing English please with hãy every time.

Using không instead of đừng for an ordinary negative command

• Wrong for “Don’t open the door”: Không mở cửa.
• Right: Đừng mở cửa.
• Why: không normally negates a statement, while đừng directly tells someone not to act. Short signs may omit words, but đừng + verb is the dependable conversational pattern.

Putting the softening particle in the wrong place

• Wrong: Nhé chờ tôi.
• Right: Chờ tôi nhé.
• Why: In this use, nhé is sentence-final. It colors the complete request rather than introducing it.

Assuming đi always means “go”

• Misreading: Ăn đi as “eat and go.”
• Right meaning: Ăn đi. — “Go ahead and eat.”
• Why: After another verb, đi can be a final particle urging the listener to do that action. Compare bare Đi!, where it is the main verb “go.”

Ignoring address terms

• Potentially abrupt: Đưa đây. — “Give it here.”
• Better in a polite interaction: Anh/chị cho tôi xem cái này được không? — “Could you let me see this?”
• Why: English relies heavily on please and could. Vietnamese also relies on appropriate address terms and relationship-sensitive wording. Do not guess a kinship term solely from a dictionary gloss; learn it in the social context where you hear it.

Using a direct command when a question is safer

• Too forceful for some situations: Nói lại đi. — “Say it again.”
• More polite to a stranger: Anh/chị nhắc lại được không? — “Could you repeat that?”
• Why: A được không? request gives the listener room to agree and is often a safer choice when you do not have authority or familiarity.

Usage Notes

Politeness is distributed across the sentence

There is no single Vietnamese word that matches every use of English please. A polite request may combine an address term, a request frame, a softer particle, and a calm tone: Chị mở cửa giúp em nhé. Here chị addresses the listener, em identifies the speaker relative to her, giúp frames the action as help, and nhé seeks friendly cooperation.

English speakers may overuse xin because bilingual signs often translate it as please. Xin is excellent in formal requests and conventional expressions, but everyday speech may prefer giúp, nhé, or được không?. Likewise, vui lòng is courteous but belongs especially to notices, instructions, and service encounters.

Directness depends on the relationship

A parent speaking to a child, close friends, a teacher giving classroom instructions, and a customer speaking to staff do not use identical wording. A bare verb is not inherently rude: Cẩn thận! (“Careful!”) is appropriate as an urgent warning, and Mời vào (“Come in”) is a conventional invitation. Still, when unsure, a question with được không? is often safer than a bare command.

Punctuation cannot show the full tone

Written exclamation marks suggest force or urgency, but spoken pitch, length, volume, facial expression, and the final particle all matter. Ngồi đi can be a warm invitation or an impatient push depending on delivery. Learn whole audio phrases rather than assigning a fixed emotional meaning to a particle.

Beyond the Basics / Advanced Use

You do not need to master every particle at A1, but you will soon encounter combinations that make commands more conversational. nào can rally people into an action: Đi nào! (“Come on, let’s go!”). thôi can signal that it is time to begin or stop another activity: Về thôi (“Let’s go home”). cứ + verb + đi can grant permission or reassure someone to continue: Cứ hỏi đi (“Go ahead and ask”).

More advanced Vietnamese distinguishes requests through speaker–listener roles rather than through verb forms. The same action may be phrased as Mời bác ngồi, Chị ngồi đi, Em ngồi nhé, or Vui lòng ngồi chờ, depending on who speaks, who listens, and why. This is part of pragmatics (how context and social relationships shape meaning), not verb conjugation.

Commands can also be reported or embedded inside longer sentences: Cô ấy bảo tôi đợi means “She told me to wait.” Here đợi still does not change form, but the sentence is no longer a command spoken directly to the listener. At later levels, you will learn verbs such as bảo (“tell”), yêu cầu (“request/require”), and khuyên (“advise”) and how their strength and register differ.

Finally, avoid treating the particles as a mechanical politeness scale. nhé is often warm, but it can sound insistent when the speaker assumes agreement. đi can encourage, permit, or impatiently urge. Meaning emerges from the phrase, relationship, and intonation together.

Practice Tips

1. Build five-way pattern sets. Take one useful verb phrase, such as đóng cửa (“close the door”), and say: Đóng cửa, Hãy đóng cửa, Đừng đóng cửa, Đóng cửa nhé, and Đóng cửa giúp tôi được không? Notice that the verb itself never changes.
2. Learn requests with a situation attached. Pair Vui lòng xếp hàng with a public notice, Xin chờ một chút with customer service, and Chờ mình nhé with a friend. This prevents you from treating all polite forms as interchangeable.
3. Listen for the last word. In dialogue, pause after each command and identify nhé, đi, nào, or thôi. Copy the full phrase and intonation, not just the dictionary meaning of the particle.
