Meaning & Usage
In Vietnamese grammar, indirect wh-questions are formed by embedding a question clause within a main sentence, typically following the verb hỏi (to ask). At the B2 level, mastering this structure is essential for reporting conversations, formal writing, and nuanced social interactions. Unlike English, which often requires a shift in verb tense (backshifting) or changes in word order (e.g., "What is his name?" vs. "I asked what his name was"), Vietnamese is much more straightforward. The internal structure of the question clause usually remains identical to its direct question counterpart.
The primary mental model for an English speaker should be: Main Clause + Reporting Verb + The Original Question. However, there are stylistic nuances. To make an indirect question sound more natural or less demanding, native speakers often insert particles like là (that/is) or xem (to see/check) between the reporting verb and the question clause. For example, hỏi xem suggests a sense of inquiry or checking for information, whereas hỏi là is a more direct reporting of what was asked.
This grammar point also covers a wide range of interrogative pronouns beyond just gì (what), ai (who), and đâu (where). It includes khi nào/bao giờ (when), tại sao (why), như thế nào (how), and bao nhiêu (how much/many). Understanding how these words function as "indefinite pronouns" in indirect speech is key to professional-level fluency. In formal contexts, especially in Northern Vietnamese, you might hear hỏi xem more frequently to maintain a polite distance, whereas in the South, the structure might be shortened or simplified in casual speech.
Structure & Formation
The basic structure for indirect wh-questions follows a predictable SVO (Subject-Verb-Object) pattern. The "Object" in this case is the entire embedded question.
| Sentence Part | Vietnamese Component | Example |
|---|---|---|
| Subject | Person asking | Giám đốc (The director) |
| Reporting Verb | hỏi / hỏi xem / muốn biết | hỏi (asked) |
| (Optional) Recipient | Person being asked | tôi (me) |
| Question Clause | S' + V' + Interrogative | anh ấy đi đâu (where he went) |
Common variations include:
- Basic Reporting: Subject + hỏi + [Question Clause]
- Softened Inquiry: Subject + hỏi xem + [Question Clause]
- Formal Clarification: Subject + hỏi là + [Question Clause]
- Self-Reflection (Wondering): Subject + tự hỏi + [Question Clause]
Note that in Vietnamese, the interrogative pronoun (wh-word) stays in its natural syntactic position. If you are asking "what" (object), the word gì stays after the verb. If you are asking "where" (location), đâu stays at the end of the phrase.

Common Mistakes
Mistake 1: English-style Word Order Inversion
❌ Tôi hỏi anh ấy là đâu anh ấy sống.
✅ Tôi hỏi anh ấy là anh ấy sống ở đâu.
English speakers often try to pull the question word (where/đâu) to the front of the clause. In Vietnamese, the question word must remain in the position where the answer would be. Since you live "at a place," the word "đâu" must follow the verb "sống".
Mistake 2: Missing the Verb 'Là' or 'Xem' in Formal Contexts
❌ Giám đốc hỏi tôi tôi làm gì.
✅ Giám đốc hỏi tôi là tôi đang làm gì.
While the first sentence is grammatically possible in very casual speech, it sounds abrupt or "choppy" in professional or B2-level contexts. Using là or xem helps bridge the two clauses and makes the sentence flow naturally.
Mistake 3: Misusing 'Rằng' instead of 'Là'
❌ Anh ấy hỏi rằng tôi đi đâu.
✅ Anh ấy hỏi xem tôi đi đâu.
While rằng is a common subordinating conjunction (meaning "that"), it is almost exclusively used with verbs of speaking or thinking like nói (say) or nghĩ (think). For indirect questions, là or xem is the standard choice. Using rằng here sounds overly literary or archaic.
Mistake 4: Subject-Verb Disconnect
❌ Cô ấy hỏi tôi là ai đã mua.
✅ Cô ấy hỏi tôi xem ai là người đã mua cái đó.
When using ai (who) as the subject of the indirect clause, it is often better to follow it with là người (is the person) to make the sentence clearer, especially if the clause is long.
Cultural Notes
In Vietnamese culture, indirectness is often a sign of politeness and social hierarchy. When a subordinate is asked a question by a superior, the reporting of that question later to others usually involves respectful markers. For instance, instead of just saying "Ông ấy hỏi..." (He asked...), a Vietnamese person might say "Ông ấy có hỏi thăm là..." (He inquired that...) to show respect.
The choice between hỏi là and hỏi xem can also reflect regional tendencies. Northern speakers (Hanoi) tend to use hỏi xem or cho hỏi frequently in formal inquiries to maintain a "standard" and polite tone. In Southern Vietnam (Saigon), people might use the word thử (to try/test) in combination: Hỏi thử xem (Ask and see). This adds a layer of casual curiosity to the inquiry.
Furthermore, the concept of "face" (thể diện) means that sometimes an indirect question is used to avoid putting someone on the spot. Instead of asking "Bạn bao nhiêu tuổi?" (How old are you?) directly, someone might say "Cho mình hỏi là bạn sinh năm bao nhiêu?" (May I ask what year you were born?). The use of the indirect structure hỏi là softens the intrusion.
Practice Tips
For the NLTV (Vietnamese Language Proficiency Test) at the B2 level, you will likely encounter indirect wh-questions in the "Listening" and "Reading" sections. Pay close attention to the particles following the verb hỏi. If you hear hỏi xem, the speaker is often looking for a specific piece of information or verification. If you hear hỏi tại sao, the focus is on the reasoning or justification.
A great way to practice is to take a direct question from a newspaper interview and try to rewrite it as a reported sentence. For example, if a journalist asks: "Ông nghĩ gì về vấn đề này?" (What do you think about this issue?), rewrite it as: "Phóng viên hỏi ông ấy là ông ấy nghĩ gì về vấn đề đó." Note how này (this) often changes to đó (that) when moving from direct to indirect speech, just like in English.
Another tip for Hán-Việt learners: The word hỏi is related to the Hán-Việt word vấn (問). You see this in phỏng vấn (interview) or vấn đề (problem/question). When you see these formal words, the indirect structure hỏi...gì/ai/đâu is almost always applied to report the findings of such inquiries.
