A dozen Vietnamese phrases cover most of what a parent needs at preschool: a greeting such as "chào cô", a thank-you such as "cảm ơn cô", a few words about eating, sleeping and health, and the polite particle "dạ". Combined with the right pronoun for the teacher, they make a real difference to how warmly you are received. You do not need fluent Vietnamese to use them, and teachers are almost always delighted when an international parent tries.
This guide gives the phrases grouped by situation, with a rough guide to pronunciation and a short explanation of how Vietnamese pronouns work, which is the part most beginners find confusing. The phrases are written with full Vietnamese diacritics, because the marks show the tones that change the meaning. Saigon pronunciation differs from northern pronunciation in several sounds; the notes below follow the southern way of speaking you will hear at school.
Pronouns first: who is "you" and who is "me"?
Vietnamese speakers rarely use a neutral word for "I" and "you" in everyday family and school conversation. Instead they choose kinship words based on age and relationship. A teacher is cô (female) or thầy (male). A child calls themselves con when speaking to a teacher or parent. Parents talking to a teacher who is younger than them often call themselves chị (older sister, for a mother) or anh (older brother, for a father), and may call the teacher em in private, while still using cô in front of the children.
This sounds complicated, but in practice you need only a few combinations. As a parent, "Chị cảm ơn cô" or "Anh cảm ơn cô" means "thank you, teacher", with you placed politely as the older sibling. If the teacher is older than you, or you are unsure, simply saying "cảm ơn cô" without any pronoun for yourself is completely natural. Vietnamese often drops pronouns when the meaning is clear.
Teachers will usually refer to you as ba bé or mẹ bé followed by your child's name, meaning "father of" or "mother of" that child. If your daughter is called Emma, you are mẹ bé Emma at school. Children also use kinship terms with each other: an older classmate is anh or chị, a younger one em. Your child will pick this up quickly, and it is a sign they are absorbing the social rules of the class.
Other adults at school follow the same logic. The guard at the gate might be chú, uncle, if he is older, or anh if he is around your age; the kitchen staff are often called cô or chị depending on age. If you are not sure, listen to how the teachers and the children address them and copy it. Using the right word is a small courtesy that people notice, and getting it slightly wrong is always forgiven.
Greetings and courtesy
These are the phrases you will use every day. The pronunciation notes are approximate, aimed at English speakers in Saigon.
| Vietnamese | Meaning | Rough pronunciation |
|---|---|---|
| Chào cô / Chào thầy | Hello, teacher (female / male) | chow koh / chow tay |
| Con chào cô | Hello, teacher (said by a child) | kon chow koh |
| Cảm ơn cô | Thank you, teacher | kahm uhn koh |
| Dạ | Polite "yes" or "I am listening" | yah (falling, short) |
| Không sao | No problem, it is fine | khom sow |
| Xin lỗi | Sorry, excuse me | sin loy |
| Hẹn gặp lại | See you again | hen gup lie |
| Chúc mừng năm mới | Happy new year (at Tet) | chook muhng nahm moy |
"Dạ" deserves special attention. Southern Vietnamese use it constantly to soften answers and show respect, especially when speaking to someone older or in a formal role. Saying "dạ" before "cảm ơn cô" or simply in reply when a teacher speaks to you instantly makes your Vietnamese sound more polite. Children are taught to start their answers to adults with "dạ", so you will hear your child doing it too. The opposite habit is worth knowing too: answering an older person with a bare "có" or "không", yes or no, without "dạ" can sound abrupt in the south, which is why teachers gently correct children who forget it.
Notice also that "cảm ơn" is used a little less often between Vietnamese family members than "thank you" is in English, while it is used freely with teachers and service staff. Thanking a teacher at every pick-up is never too much.
At drop-off: telling the teacher what matters
Short phrases to pass on information in the morning. Pair them with pointing or a quick note in the parent app if you are unsure the message got through. The word bé, meaning little one, is how teachers and parents refer to a young child, and it works in place of your child's name in all these sentences.
| Vietnamese | Meaning |
|---|---|
| Hôm nay bé hơi mệt. | My child is a bit tired today. |
| Tối qua bé ngủ không ngon. | My child did not sleep well last night. |
| Sáng nay bé chưa ăn sáng. | My child has not had breakfast this morning. |
| Bé bị dị ứng tôm. | My child is allergic to shrimp. |
| Đây là quần áo dự phòng. | Here are spare clothes. |
| Chiều nay ông bà đón bé. | Grandparents will pick up my child this afternoon. |
| Chiều nay chị đón sớm. | I (a mother) will pick up early this afternoon. |
Replace tôm, shrimp, with the relevant word for allergies: đậu phộng for peanuts, trứng for egg, sữa bò for cow's milk. For anything medical, always back up the spoken message in writing through the school's official channel; a phrase at the gate is a courtesy, not a medical handover.
If you use a nanny or driver for drop-off, teach them the same phrases in reverse so they can relay messages from the teacher, or ask them to pass on anything important through the app so you have it in writing.
At pick-up: asking about the day
Teachers usually report on eating, sleeping and mood. These questions help you ask and understand the answers.
| Vietnamese | Meaning |
|---|---|
| Hôm nay bé ăn được không cô? | Did my child eat well today? |
| Bé có ngủ trưa không cô? | Did my child nap? |
| Hôm nay bé có ngoan không cô? | Was my child good today? |
| Bé ăn hết / ăn ít. | Ate everything / ate a little. |
| Bé ngủ ngon. | Slept well. |
| Bé bị sốt / bị ho. | Has a fever / has a cough. |
| Cô nói chậm một chút được không? | Could you speak a little more slowly? |
"Ngoan" is one of the most important words in Vietnamese parenting, meaning good, obedient and well-behaved all at once. Teachers use it as warm praise. When a teacher says "bé ngoan lắm", your child was very good. If they hesitate before answering, a follow-up in English or through the app often tells you more.
Teachers may also use a few words you will hear again and again: "bé quấy" means the child was fussy or unsettled, "bé khóc" means cried, "bé chơi với bạn" means played with friends, and "bé tự ăn" means fed themselves. Recognising these words lets you pick up the gist of a quick report even if the rest of the sentence goes past too fast, and you can then ask for more detail in English or through the parent app.
Phrases for special moments
A handful of phrases for the occasions that come round each school year. Even saying one of them at the right moment is remembered.
| Vietnamese | Meaning | When to use it |
|---|---|---|
| Chúc mừng sinh nhật | Happy birthday | A classmate's birthday at school or a party |
| Chúc mừng ngày Nhà giáo | Happy Teachers' Day | On or around 20 November |
| Chúc cô sức khỏe | Wishing you good health, teacher | At Tet, on Teachers' Day, or when a teacher has been ill |
| Chúc mừng năm mới | Happy new year | In the weeks around Tet |
| Trung thu vui vẻ | Happy Mid-Autumn Festival | In the days before the full moon of the eighth lunar month |
| Cô vất vả quá | You have had a hard day, teacher | A kind acknowledgement after a busy event or a difficult day |
| Tạm biệt cô | Goodbye, teacher | At pick-up, or at the end of the school year |
"Cô vất vả quá" is worth learning even if you learn nothing else on this list. It expresses sympathy for the effort someone has made, and teachers often hear it from Vietnamese parents after performances, outings or long days. From an international parent it shows real understanding of how much work goes into caring for a class of small children.
At the end of a school year, a card that combines a short Vietnamese phrase in your child's handwriting with a longer message in English is a lovely keepsake for teachers.
Tones and sounds: what helps a beginner most
Vietnamese is tonal: the same syllable said with a different pitch becomes a different word. Southern speech has five audible tones, because two of the northern tones merge. You do not need to master them to be understood in context, but a few points help:
- Listen before you speak. Ask a teacher or a Vietnamese friend to say a phrase several times and copy the melody rather than the spelling.
- Pay attention to "cô". Said flat, it means teacher or aunt. With other tones it becomes different words, so keep it level and steady.
- Southern "v" and "d" often sound like an English "y". This is why "dạ" sounds like "yah" in Saigon.
- Final consonants are clipped. The "t" in "một" or the "p" in "gặp" is barely released; do not add a vowel after it.
- Short and clear beats long and wrong. "Cảm ơn cô" said warmly is better than a complicated sentence nobody follows.
- Use your child as a teacher. Preschoolers in bilingual classes often correct their parents' tones with great pleasure. Let them.
Many families find that a few short lessons with a tutor focusing on everyday school and home phrases are more useful than a general course. A recorder app on your phone, used to save the teacher saying key phrases, also works well.
What your child will start saying, and how to respond
Children in bilingual preschools pick up Vietnamese school routines quickly. Within weeks you may hear your child say "dạ" when called, "con chào cô" at the gate, "con mời ba mẹ ăn cơm" before dinner, which is the polite invitation to elders before a meal, or "cô ơi", the way to call for a teacher's attention. They may also start calling older children anh and chị, and refer to themselves as con.
Responding warmly in kind is the best encouragement. If your child invites you to eat, saying "ừ, con ăn đi" or simply "thank you" in your own language, with a smile, tells them their new words are welcome at home. Asking your child to teach you a word each day turns their bilingual school life into something you share, and many children enjoy being the expert.
If you do not speak Vietnamese at home, do not worry that your child will lose it outside school. Steady exposure at preschool is what builds the language at this age; your role is to value it. Asking about songs, enjoying Vietnamese picture books together and greeting teachers in Vietnamese all send the message that both languages matter.
Câu hỏi thường gặp
How do I say thank you to my child's teacher in Vietnamese?
Say cảm ơn cô for a female teacher or cảm ơn thầy for a male teacher. Adding dạ at the start, as in dạ cảm ơn cô, makes it sound even more polite. Mothers can say chị cảm ơn cô and fathers anh cảm ơn cô.
Which pronoun should I use for myself with a teacher?
If the teacher is younger, mothers often say chị and fathers anh, meaning older sister or brother. If the teacher is older or you are unsure, leave the pronoun out and simply say the sentence. Vietnamese often drops pronouns when the meaning is clear.
Is southern Vietnamese very different from northern Vietnamese?
The grammar and most vocabulary are the same, but pronunciation differs and some everyday words change. Southern speech merges two tones and pronounces several consonants differently. If you live in Ho Chi Minh City, learning the southern accent will help you understand teachers and staff.
What does ngoan mean when teachers talk about my child?
Ngoan means good, well-behaved and cooperative, and it is warm praise in a Vietnamese school. Bé ngoan lắm means your child was very good. Teachers use it about eating, sleeping and joining in with the group as well as behaviour.
Should I write to teachers in Vietnamese or English?
Use whichever language the school officially supports. Many bilingual preschools reply in English, and some parent apps translate messages. For anything important, such as allergies or medication, write in clear English and ask for confirmation, rather than relying on uncertain Vietnamese.
How long does it take to learn useful Vietnamese for school?
Most parents can use the greetings and a handful of phrases within a few weeks of regular practice. Being comfortable in longer conversations takes far longer. Focus on what you use every day, and let teachers and your child help with pronunciation.
