When đi follows another verb or its object, it can add a path away from the relevant deictic center: mang rác đi “take the rubbish away,” cất giấy tờ đi “put the documents away,” and đuổi nó đi “drive it away.” This postverbal đi differs from initial đi in đi mua đồ “go buy things.” It also overlaps in surface position with final particle đi, which encourages, permits, or softens an action: Ăn đi! “Go ahead and eat!”
Directional đi: removal from the current scene
The most transparent directional pattern is verb + object + đi. The verb describes the action that causes movement; đi says that the affected entity leaves the current place, possession, or discourse center.
Em mang mấy cái hộp này đi giúp chị nhé.
Please take these boxes away for me.
Gió thổi tờ giấy bay đi mất.
The wind blew the sheet of paper away completely.
Bảo vệ đã đưa người đàn ông đó đi.
Security took that man away.
The center need not literally be the speaker’s body. It can be the room, household, scene, or reference location currently in focus. Đưa người đàn ông đó đi means that the man is removed from that center. Context supplies the destination, and it may remain unspoken.
With no overt object, the subject itself may move away:
Nghe tin xong, anh ấy bỏ đi mà không nói gì.
After hearing the news, he left without saying anything.
Con mèo thấy người lạ thì chạy đi mất.
When the cat saw a stranger, it ran off.
In bỏ đi, the combination conventionally means leave or go away. Mất after a motion or disappearance sequence can emphasize complete loss from view or an unwanted outcome. It is not a past-tense ending.
Event order and the position of the object
Vietnamese preserves the iconic order action → path. With a transported object, the neutral sequence is normally V + object + đi.
Đừng vứt hóa đơn đi; tôi vẫn cần nó.
Don’t throw the receipt away; I still need it.
Sau khi quét nhà, cô ấy mang rác đi.
After sweeping the floor, she took the rubbish away.
The object is affected by the first verb and follows the path contributed by đi. English often places “away” before a long object or treats it as a phrasal-verb particle; Vietnamese has its own ordering and should not be rearranged word by word.
Compare the direction with a return toward a reference point:
Mang hồ sơ đi rồi nhớ mang nó lại đây trước năm giờ.
Take the file away, and remember to bring it back here before five.
The opposition đi versus lại đây changes the path: removal versus movement back toward the stated center. The next page treats the several meanings of postverbal lại in detail.
For the larger caused-motion frame in which the object stands between the transport verb and direction, see transport verbs plus direction.
Directional đi versus purpose-initial đi
Position and event structure distinguish two common uses:
| Pattern | Role of đi | Example |
|---|---|---|
| đi + activity | initial motion whose purpose follows | đi mua đồ “go buy things” |
| V + object + đi | away-path of an affected entity | mang sách đi “take the books away” |
| V + đi! | possibly a final urging/permission particle | Ăn đi! “Go ahead and eat!” |
Tôi đi mua đồ rồi mang thẳng đến nhà chị.
I’ll go buy the things and then take them straight to your house.
Here initial đi launches a shopping errand. In contrast, mang đồ đi would remove the things from the current center without naming their destination.
The crucial ambiguity: direction or final particle?
Sentence-final đi does not always encode physical motion. In commands, suggestions, encouragement, or permission, it can be a modal discourse particle. The action itself may happen in place.
Ăn đi, không là nguội đấy.
Go ahead and eat, or it’ll get cold.
Nói đi, mình đang nghe đây.
Go on, tell me; I’m listening.
Cứ thử đi rồi sẽ biết.
Just try it and you’ll see.
No food, speech, or attempt necessarily moves away. The particle presents the proposed action as something the addressee should proceed with. It is frequent in conversation (informal) and its force ranges from warm encouragement to impatience depending on intonation and surrounding words.
Some strings permit both analyses. Cầm đi! can mean “Take it away!” when an object is understood and removal matters, or roughly “Go ahead, take it” when đi helps license the command. Context, gesture, prosody, and whether a destination contrast is active determine the reading.
Cất điện thoại đi!
Put your phone away!
This usually combines a lexical removal/result meaning with imperative force. It is unhelpful to insist that every instance contains only one sharply separable function; grammaticalization creates genuine overlap. What matters for learners is recognizing that final đi does not automatically mean a new journey.
Scope, completion, and result
Markers around the series show whether removal occurs, remains pending, or fails.
Tôi chưa mang những thùng này đi.
I haven’t taken these boxes away yet.
Họ đã chuyển hết đồ đi rồi.
They’ve moved all the belongings away already.
Tôi kéo mãi mà không lấy cái đinh ra được.
I kept pulling but couldn’t get the nail out.
The third example uses ra, not đi, because the relevant result is extraction from an enclosure or surface. Không … được denies successful attainment. Choosing a direction word requires understanding the geometry of the event, not substituting a generic English “away.”
The broad family remains visible in a minimal contrast:
| Sequence | Constructional relation |
|---|---|
| đi mua đồ | motion plus purpose |
| mang sách về | transport plus return/homeward direction |
| ăn hết cơm | activity plus total result |
| mở cửa ra | caused change plus outward/open result |
| làm cho tôi hiểu | causation plus resulting state |
Postverbal directional đi patterns most closely with mang sách về: the later element modifies the path of the integrated event. Final particle đi belongs to interactional grammar instead.
A natural dialogue with both uses
Mẹ: Con mang mấy túi rác này đi nhé. — Con: Bây giờ ạ? — Mẹ: Ừ, mang đi, mùi khó chịu quá. Xong rồi vào ăn đi, cơm sắp nguội rồi.
Mother: Take these rubbish bags away, please. — Child: Now? — Mother: Yes, take them out; the smell is awful. When you’re done, come inside and eat—the meal is getting cold.
The first two instances of mang … đi remove rubbish from the house. In ăn đi, nothing travels away; final đi urges the child to begin eating. Vào carries the genuine inward direction in that last instruction.
Direction or particle? A quick guide
| Clue | Directional đi | Final particle đi |
|---|---|---|
| Moving entity | identifiable subject or object | none required |
| Meaning | away/removal | proceed, go ahead, do it |
| Sentence type | statement, question, or command | especially commands and suggestions |
| Possible contrast | lại, về, ra, vào | contrast in interpersonal tone |
| Example | mang ghế đi | ngồi đi |
Common Mistakes
Inserting an English infinitive marker
❌ Tôi mang rác để đi.
Incorrect for ‘I take the rubbish away’; để turns what follows toward a purpose-clause interpretation.
✅ Tôi mang rác đi.
I take the rubbish away.
Directional đi directly completes the transport event. It is not an infinitive after English “to.”
Reversing the iconic order
❌ Tôi đi mang rác.
This means ‘I go to take/carry the rubbish,’ not ‘I take the rubbish away.’
✅ Tôi mang rác đi.
I take the rubbish away.
Initial đi makes the later action its purpose. Final directional đi gives the affected object an away-path.
Reading every final đi as physical movement
✅ Ăn đi, đồ ăn sắp nguội rồi!
Go ahead and eat; the food is getting cold!
The incorrect analysis is “eat and travel away.” The eating occurs in place: đi manages the interaction rather than the path.
Dropping the object before direction
❌ Tôi mang đi sách.
Unnatural as the neutral transport-direction order.
✅ Tôi mang sách đi.
I take the books away.
Put the transported object after mang and before đi.
Key Takeaways
- Postverbal directional đi presents movement or removal away from a contextual center.
- In transport structures, use verb + object + đi.
- Initial đi in đi mua đồ introduces motion plus purpose; it is structurally different.
- Final đi in Ăn đi! is a conversational particle, not a direction verb.
- Some imperatives allow overlap between path and particle meanings; use participants, context, and prosody.
- The return/repetition meanings of lại require their own analysis on the next page.
