Common Vietnamese Grammar Mistakes for English Speakers
English habits often produce understandable but unnatural Vietnamese. These corrections target the most common points of interference.
Sentence structure
Using là before every adjective
Vietnamese adjectives can act as predicates without a form of “to be.”
Avoid: Cô ấy là đẹp.
Use: Cô ấy đẹp.
Putting adjectives before nouns
Most descriptive adjectives follow the noun in Vietnamese.
Avoid: một đẹp ngôi nhà
Use: một ngôi nhà đẹp
Moving question words to the front
Vietnamese question words usually stay where the missing information belongs.
Avoid: Gì bạn muốn ăn?
Use: Bạn muốn ăn gì?
Meaning and context
Treating tense markers like English verb tense
đã, đang, and sẽ mark time or aspect when the context needs them; Vietnamese verbs do not conjugate.
Translating articles word for word
Vietnamese has demonstratives, numerals, and classifiers, but no direct equivalent of English “a” and “the.”
Leaving speech unsoftened
A grammatically complete request may still sound abrupt without an address term, nhé, ạ, giúp, or another politeness strategy.

là
to be (is/are/am)
'là' is commonly used to mean 'to be' and is a fundamental structure for learners.

I am a student.
đã
already
'đã' is commonly used to indicate that an action has already happened.

I have already eaten.
đang
currently (in progress)
'đang' is commonly used to indicate an action is currently in progress.

I am studying Vietnamese.
sẽ
will (future tense)
'sẽ' is commonly used to indicate future actions or events.
Ngày mai tôi sẽ đi Hà Nội.
I will go to Hanoi tomorrow.
nhé
please; okay
The particle nhé is commonly used to express a soft command or suggestion, similar to "please" or "okay" in English. It is an important structure for learners to master.
Mai gặp lại nhé.
See you again tomorrow, okay.
cái
piece; item; general classifier for objects
'cái' is the most common classifier for objects in Vietnamese, used for general items and things you can pick up. It also appears in phrases like 'this one' or 'that one.'
Tôi mua một cái bàn mới.
I bought a new table.
N + tính từ
adjectives follow nouns
In Vietnamese, adjectives usually come after the noun they modify, for example áo đỏ ('red shirt').
Tôi mua một cái áo đỏ.
I bought a red shirt.
từ hỏi ở vị trí nội dung
Question words stay in content position
Vietnamese question words usually stay in the position of the information being asked about, not at the beginning of the sentence.
Bạn ăn gì?
What do you eat?
