Grammar Rule in 30 Seconds

In Vietnamese, verbs never change their form; instead, you use time words to indicate when an action happens.

  • Verbs stay the same regardless of who is doing the action: 'Tôi ăn' (I eat/ate), 'Họ ăn' (They eat/ate).
  • Use time markers like 'đã' (past), 'đang' (present continuous), or 'sẽ' (future) before the verb to clarify time.
  • If the time is clear from context, you can omit the marker entirely to sound more natural.
Time Marker + Verb = Action in Time

Context is King

If the time is obvious, don't use a marker. It sounds more natural.
⚠️

No Conjugation

Stop looking for verb endings. They don't exist.
🎯

Use 'không'

Always place 'không' directly before the verb.
💬

Regional Variation

Southern speakers use 'rồi' more often than Northern speakers.

Smart Tips

Drop the marker if the time is already mentioned in the sentence.

Hôm qua tôi đã đi chợ. → Hôm qua tôi đi chợ.

Focus on the time word (yesterday, tomorrow) rather than the verb.

Tôi ăned yesterday. → Hôm qua tôi ăn.

Use markers to ensure clarity in professional settings.

Tôi làm việc đó. → Tôi đã làm việc đó.

Use 'không' at the end for yes/no questions.

Bạn ăn? → Bạn ăn không?

النطق

dă, dăng, sĕ

Marker stress

Time markers are usually unstressed.

Question intonation

Bạn ăn không? ↑

Rising pitch at the end indicates a question.

وسيلة تذكّر

Vietnamese verbs are like statues: they never move, no matter the weather (time).

ربط بصري

Imagine a stone statue of a person eating. No matter if you put a 'Yesterday' sign or a 'Tomorrow' sign next to the statue, the statue itself stays exactly the same.

Rhyme

Verbs in Vietnam, stay just the same, no matter the time, they keep their name.

Story

Imagine you are a builder. You have one brick that says 'Eat'. You want to say 'I ate'. You don't change the brick. You just put a 'Past' sticker on the wall next to it. You want to say 'I will eat'? Just swap the 'Past' sticker for a 'Future' sticker. The 'Eat' brick stays perfect.
