Vietnamese for IT Professionals: Vocabulary, Pronouns and Real Dialogues

You join a software team in Ho Chi Minh City or work with an outsourcing team in Hanoi. At the first stand-up someone says: Hôm qua em đã fix xong cái bug ở màn hình login, hôm nay em sẽ làm tiếp phần API. You catch fix, bug, login and API. Everything in between goes past you.

That is a common first experience. Many Vietnamese developers drop English technical terms into Vietnamese sentences, so the nouns are often the part you already know. What slows you down is the frame around them: who is addressing whom as anh, chị or em, which small word marks a finished action, and how a request is softened so it sounds like a colleague and not an order.

This article is for engineers, testers and project managers who work with Vietnamese-speaking teammates or clients. It has vocabulary grouped by what happens in a project, five grammar points, three dialogues you can read aloud and a game to play at the end. Most Vietnamese teams can also work in English, so none of this is a requirement. It is what makes the side conversations, and the trust that grows from them, much easier.

Three kinds of Vietnamese on a software team

Vietnamese does not conjugate verbs, but it marks relationships heavily through pronouns and small particles. The table shows what you will typically hear in a software company.

The third style is the easiest for foreigners. Ticket titles and commit messages are short, and many technical words are written in English exactly as in your own team. The first two styles are where the pronoun choice matters, and that is the topic of the first grammar point below.

One more note on spelling. Vietnamese is written in the Latin alphabet with tone marks, and the tone changes the word. A few pairs from daily work make the point: nhanh means fast and nhánh means branch, sửa means to fix and sữa means milk. In chat you may see people drop the marks, but in documents and ticket titles they are normally written.

Vocabulary for a working day in a Vietnamese team

The tables follow the order in which a project runs. The set you play in the game is the first 41 entries across these five tables, plus a few extras such as bị kẹt, xác nhận and làm rõ that you will hear almost immediately.

Clients, requirements and documents

Notice that the example sentences use three different words for "I": anh, chị and em. They are not interchangeable. They tell the listener whether the speaker is older or younger than the listener, and the next sections come back to this.

Meetings, schedule and estimates

Vietnamese team members often say họp daily or just daily. Họp means to hold a meeting and is the verb that goes with almost any meeting: họp nhóm, họp khách hàng, họp tiến độ. It is worth learning as a unit.

Code, review and testing

Many of these entries are not translated at all. Vietnamese developers say commit, pull request, log and API as in English, and they attach Vietnamese grammar around them. Others, such as nhánh, gộp and máy chủ, are real Vietnamese words. Learn both groups, because a single team uses both.

Bugs and incidents

Lỗi and sự cố are not the same size. Lỗi is a specific bug, and sự cố is an incident that affects the service or many users. When someone says có sự cố rồi (there is an incident now), the conversation moves to the incident channel and the usual tasks pause.

Environments and releases

Nghiệm thu is the word to learn in any project with an outside client. It means the client checks the work against what was agreed and signs it off, and it is usually tied to the final payment. In conversation, people also say test nghiệm thu for the acceptance test.

Five patterns behind everyday workplace Vietnamese

1. Pronouns: anh, chị, em, bạn, mình, tôi

Vietnamese has no single word for "I" and "you". Instead people use kinship terms by relative age and seniority. Anh is an older man or a male senior, chị is an older woman or a female senior, and em is someone younger or junior. Speakers use the same word for themselves and for the other person, depending on who is talking. Bạn is a neutral word for peers, mình means "I" or "we" in a friendly way, and tôi is a plain, slightly formal "I".

• Anh ơi, anh review giúp em cái pull request này nhé.
• Chị Hà, em xin báo cáo tiến độ ạ.
• Mình họp lúc chín giờ nhé.

The usual learner mistake is to translate "I" and "you" as tôi and bạn in every sentence. It is grammatically correct, and in team chat it sounds distant, like a formal letter. A safer approach is to ask once how people want to be addressed. Many Vietnamese colleagues will call you anh or chị followed by your first name, and you can reply in the same way or use their name with anh, chị or em depending on age.

2. Polite particles: ạ, dạ, nhé, giúp

Ạ marks respect at the end of a sentence when you speak to someone older or more senior. Dạ is a polite "yes" or an answer to being called. Nhé is a softener that turns a statement into a friendly request or confirmation, and in the south people often say nha. Giúp, as in anh giúp em, means "help me" and is the natural way to ask for a favour in a team.

• Dạ, em xem ngay ạ.
• Chị gửi giúp em log được không ạ?
• Anh review giúp em nhé.

A common mistake is to translate "please" as làm ơn. It is correct but sounds like a plea for a favour, which is heavier than most work requests need. For normal requests, giúp plus nhé is the usual form, and ạ at the end if the person is senior. Overusing ạ in every sentence to a peer can sound strange, so listen to how teammates use it.

3. Đã, đang, sẽ, rồi, chưa: status updates

Vietnamese verbs do not change form. Time is shown by small words before the verb: đã for something done, đang for in progress, sẽ for future. At the end of a sentence, rồi means "already" and chưa means "not yet".

• Em đã sửa lỗi rồi.
• Em đang điều tra nguyên nhân.
• Em sẽ triển khai tối nay.
• Chưa lên production.

Learners tend to add đã to every past event. Vietnamese often drops the marker when the time is clear from context: Hôm qua em sửa xong lỗi đó is perfectly natural. Another distinction that matters in a status update is chưa versus không. Chưa lên production means it is not live yet, while không lên production means it will not go live.

4. Questions with không, chưa and sao

Yes and no questions are built by placing không at the end, or chưa when asking whether something has happened yet. Sao means "why". Answers often repeat the verb or use rồi and chưa, and dạ or vâng adds politeness.

• Lỗi này tái hiện được không?
• Anh review xong chưa ạ?
• Sao lỗi này chỉ xảy ra trên staging?

A common mistake is to answer a không question with a bare có or không, which can sound abrupt to a senior. A fuller answer repeats the verb: Tái hiện được (Yes, it can) or Không tái hiện được (No, it cannot). For chưa questions, answer rồi (already) or chưa (not yet). For example, to Anh review xong chưa ạ? you answer Rồi, or Chưa, anh đang xem.

5. Loanwords and the classifier cái

English words used in Vietnamese stay unchanged. You say deploy, merge, commit in any context without adding endings. Vietnamese nouns often take a classifier. For objects and abstract items, cái is common: cái bug, cái pull request, cái ticket. Developers also use con for bugs in a jokey way, as in con bug này, treating a bug like an animal that must be caught.

• Merge xong rồi.
• Cái pull request này em tạo hôm qua.
• Con bug này khó tái hiện lắm.

The learner mistake is to try to conjugate the English word, as if it needed a past tense. You never say deployed or merging in a Vietnamese sentence. You say đã deploy, đang merge, and use xong (finished) plus rồi to show completion: Deploy xong rồi.

Three scenes: lunch, stand-up and the pre-Tet deadline

A lunch invitation

Much of a team relationship is built outside tickets. Lan is younger than you, so she says em and calls you anh, and she says tụi em for "us younger ones" (in the north you often hear bọn em).

A stand-up with a blocker

Here you are the junior, so you say em, and your team lead, anh Minh, says anh.

A deadline before Tet

Tet, the lunar new year, is the longest holiday of the year in Vietnam, and teams usually plan around it. Here you are a project manager and the register is more formal: tôi appears and the client is addressed as anh.

Đóng băng code (code freeze) is a useful phrase here. It is the date after which no new changes go into the release, only critical fixes. In the third scene the PM does not simply say no. He gives the condition, the risk and a recommendation, which is the way many Vietnamese clients prefer to hear a hard answer.

Practising alongside a real team

Play the IT set in Falling Stars or Pop It until you can see lỗi, nhánh or nghiệm thu and say the meaning. Then open a ticket or a chat channel from your own team, underline five words from the tables and read the whole sentence aloud, tone marks included.

For listening, choose an episode from the Vietnamese podcasts, listen one sentence at a time and type what you hear. Dictation shows you where you mishear, typically tones that sound close such as nhanh and nhánh, and the sentence-final particles that beginners skip. For a structured route, see the courses, and use the vocabulary test to see where you stand.

Outside WELE, VietnamesePod101 has dialogues and lessons at every level, and italki lets you book one-to-one tutors, including some who work in IT. For reading, Viblo is a Vietnamese developer community where engineers write technical posts in their own words, which shows how real teams explain things. When you want to test yourself, the VPT mock test on WELE shows where you stand.

If your team is split across time zones, a small daily habit works better than a long session: read five chat messages and note two new expressions. If you also work next to other roles, see Vietnamese for office workers and Vietnamese for freelancers, or browse all Vietnamese by profession and the IT page.

Questions people ask before working in Vietnam

Do I need Vietnamese to work with a Vietnamese dev team?

Not always. Many teams work in English, especially in outsourcing companies with foreign clients. Vietnamese becomes useful for the conversations around the work: lunch, side chat, understanding who is stuck, and getting trust from teammates. Ask your team about their working language before you plan how much to learn.

Should I learn the Hanoi or the Ho Chi Minh City accent?

Learn the one that matches your team. The core IT vocabulary is the same. The main differences are some tones and particles, for example nhé in the north and nha in the south, and a few everyday words.

Why do Vietnamese developers mix English words into Vietnamese?

Most tools and terms in software come from English, so many words simply stay as they are: commit, deploy, ticket. Others, such as lỗi, nhánh and máy chủ, are Vietnamese and are used alongside them. Which one a person picks depends on the team and the context.

How should I address my Vietnamese colleagues?

Use anh or chị plus the first name for colleagues who are clearly older than you, and em plus the first name for those younger. If you are unsure, bạn plus the first name is neutral and acceptable. After a few days, listen to how others address each other and copy that.

How important are tones?

They matter, because the tone changes the word: nhanh is fast and nhánh is a branch. Context usually saves you in a conversation, but wrong tones can make a sentence hard to understand. Learn each word with its tone from the start.

One small step

At your next stand-up, try one sentence with đã or đang, one with ạ and one with nhé, for example Em đã sửa xong rồi ạ. The set to play first is in Falling Stars.
