Mọi, Mỗi, Từng, and Distributive Reference | Vietnamese Grammar

English every and each conceal three useful Vietnamese perspectives. Mọi sweeps across a whole contextually relevant domain, mỗi distributes a relation to one member at a time, and từng makes those members individually salient—often as a deliberate sequence. All three can produce an English translation with every or each, but they organize attention differently.

They are quantificational operators, not plural articles. Vietnamese still builds the surrounding noun phrase through classifier choice and word order. This page focuses on distributive reference; small indefinite quantities with vài, dăm, and mấy belong on the next page.

The three-way contrast

Form	Core viewpoint	Typical English	Register
mọi	No relevant member is excluded; the set is viewed broadly	every, all	Unmarked in speech and writing
mỗi	The same relation is assigned separately to each member	each, every, per	Unmarked
từng	Members are distinguished one by one, often in sequence or retrospect	each individual, one by one	Unmarked; frequent in careful narration and instructions

Mọi hành khách phải xuất trình giấy tờ tùy thân.

Every passenger must show identification. (No passenger is exempt.)

Mỗi hành khách được mang một kiện hành lý xách tay.

Each passenger may bring one piece of carry-on luggage. (One allowance per passenger.)

Nhân viên kiểm tra từng hành khách trước khi mở cửa lên máy bay.

The staff check each passenger individually before opening the boarding gate.

The first sentence defines universal scope. The second establishes a passenger-to-allowance pairing. The third directs attention to the inspection of individuals in succession.

💡

Use mọi to say “none excluded,” mỗi to say “one allocation or recurrence per member,” and từng to say “member by identifiable member.”

Mọi: the whole relevant domain

Mọi presents its noun as a complete domain relevant to the claim: mọi người “everyone,” mọi nhà “every household,” mọi trường hợp “every case.” It is common in everyday speech, public notices, and (formal) generalizations.

Mọi người về đến nhà thì nhắn vào nhóm nhé.

Everyone, message the group when you get home. (informal)

Quy định này áp dụng trong mọi trường hợp.

This rule applies in every case. (formal)

An appropriate classifier may appear when individual units are made explicit: mọi con mèo, mọi cuốn sách, mọi chiếc xe. With conventional human or institutional nouns, no classifier is often needed: mọi người, mọi học sinh, mọi công ty. The construction is mọi + (classifier) + noun, never an English-style the + every combination.

Mọi con mèo trong trạm cứu hộ đều đã được tiêm phòng.

Every cat in the rescue center has been vaccinated.

Unlike mỗi, mọi can also introduce a domain whose predicate is understood collectively. Mọi người tụ tập ở căng tin means “Everyone gathered in the canteen”: the gathering involves the group, while mọi still leaves no relevant person out. Mỗi người tụ tập ở căng tin is not a natural replacement for that collective reading, because mỗi requires the relation to hold member by member.

Sau buổi họp, mọi người tụ tập ở căng tin để uống cà phê.

After the meeting, everyone gathered in the canteen for coffee. (The gathering is collective.)

Because mọi itself ranges over the set, it normally does not stack with các or những. To quantify a demonstrative group, Vietnamese often uses a partitive phrase: mọi người trong số những người này “every person among these people,” though in natural discourse a simpler noun plus modifier is preferable.

Mỗi: distribution, recurrence, and “per”

Mỗi treats members separately under the same rule. It is especially natural when the predicate contains a matching quantity: one form per applicant, two tickets per family, one visit each month.

Mỗi sinh viên chọn một đề tài.

Each student chooses one topic.

Mỗi nhà được phát hai thùng nước.

Each household was given two cases of water.

Tôi gọi cho mẹ mỗi tuần một lần.

I call my mother once a week.

The classifier can make a discrete object explicit: mỗi con mèo, mỗi quyển sách, mỗi tờ đơn. Time nouns and familiar human nouns often follow mỗi directly: mỗi ngày, mỗi người, mỗi học sinh.

Possession follows the noun as usual. Mỗi quyển sách của tôi means “each of my books,” while nhà của tôi by itself leaves number to context. A demonstrative after mỗi is possible when it identifies a type or recurring instance, but direct translations such as each these books are not. Say mỗi cuốn trong số những cuốn sách này when the partitive meaning must be explicit.

Tôi ghi ngày mua vào mỗi cuốn sách của mình.

I write the purchase date in each of my books.

The sequence mỗi một can add emphasis—“each and every single”—and sounds deliberate rather than necessary. It occurs in speech and in (formal) rhetoric.

Cô nhớ tên của mỗi một học sinh trong lớp.

She remembers the name of every single student in the class.

Từng: individualization and sequence

Từng zooms in more strongly than mỗi. It often implies that someone considers, checks, remembers, or performs an action on the members separately. Từng ... một makes the one-by-one reading explicit.

Anh ấy đọc từng trang của bản hợp đồng.

He read the contract page by page.

Nhân viên mời từng khách một vào phòng.

The staff member invites the guests into the room one at a time.

Tôi vẫn nhớ từng con phố nhỏ ở khu ấy.

I still remember every little street in that neighborhood individually.

With a past-time expression, từng also has another grammatical use meaning “once/formerly,” as in tôi từng sống ở Huế “I once lived in Huế.” That is not a noun-phrase quantifier and should not be confused with từng người. Position reveals the difference: distributive từng precedes a noun phrase; experiential từng precedes a predicate.

Tôi từng phát từng tờ phiếu cho khách.

I once handed out the forms to the guests one by one. (The first từng is experiential; the second is distributive.)

Required building blocks in context

The following contrasts show how distribution interacts with ordinary noun-phrase structure:

Phrase	What it encodes	Distributive counterpart
một con mèo	one counted cat	mỗi con mèo “each cat”
hai quyển sách	two counted books	mỗi người hai quyển sách “two books per person”
những người này	these people as a selected plural group	từng người trong số này “each one among these people”
nhà của tôi	my house/home	mỗi phòng trong nhà của tôi “each room in my house”
một bát cơm	one measured bowlful of rice	mỗi người một bát cơm “one bowl of rice per person”

Notice mỗi người một bát cơm: Vietnamese can place the distributed individual and that person's allocation side by side, without English gets or per. Context supplies the relation.

A: Chia cơm thế nào? B: Mỗi người một bát trước; ai còn đói thì lấy thêm. A: Được, để mình mang từng bát ra.

A: How should we portion the rice? B: One bowl per person first; anyone still hungry can take more. A: Okay, I'll carry the bowls out one by one. (informal)

Changing mỗi to mọi would lose the one-bowl-per-person pairing. Changing the final từng bát to các bát would refer to the relevant bowls as a set, not to carrying them separately.

Choosing among the three

Ask what the sentence is doing:

Does it make a universal statement with no relevant exceptions? Choose mọi.
Does it assign an amount, duty, or recurrence separately to members? Choose mỗi.
Does it track or process identifiable members one by one? Choose từng, optionally từng ... một.

These words do not require những or các to make their nouns plural. Nor do they create an English definite article. The noun phrase remains Vietnamese: quantifier before noun/classifier, possessor and demonstrative material after it.

💡

A plural marker collects a set; a distributive quantifier maps a statement onto members. That is why các sinh viên can act as a group, while mỗi sinh viên creates a separate obligation or allocation for every student.

Common Mistakes

Do not combine mỗi mechanically with a plural marker:

❌ Mỗi các sinh viên phải ký tên.

Incorrect: mỗi already distributes over the students; các cannot be inserted like English ‘the.’

✅ Mỗi sinh viên phải ký tên.

Each student must sign.

Keep the classifier when ordinary counting or individuation requires it:

❌ Mỗi mèo được phát một vòng cổ.

Awkward in this concrete distributive context: the animal classifier is missing.

✅ Mỗi con mèo được phát một chiếc vòng cổ.

Each cat is given a collar.

Do not stack mọi and mỗi as though English every single required two Vietnamese quantifiers:

❌ Mọi mỗi người nhận hai vé.

Incorrect: mọi and mỗi cannot be stacked in one simple noun phrase.

✅ Mỗi người nhận hai vé.

Each person receives two tickets. (The allocation is explicitly distributive.)

Do not confuse distributive từng with experiential từng:

❌ Tôi mỗi sống ở Đà Nẵng.

Incorrect for ‘I once lived in Đà Nẵng’: mỗi is a nominal distributor, not an experiential marker.

✅ Tôi từng sống ở Đà Nẵng.

I once lived in Đà Nẵng.

Key Takeaways

Mọi covers a whole relevant domain, mỗi establishes member-by-member distribution, and từng individuates members, often in sequence. Put them before the noun or classifier phrase, do not add các/những automatically, and preserve the normal placement of possession and demonstratives. The difference is not singular versus plural; it is how the speaker maps a claim onto a set.
