Putting The Object First

Level 4

Vietnamese is a highly topic-prominent language. Instead of strictly following Subject-Verb-Object (SVO) order, native speakers frequently move the object to the front of the sentence to establish it as the topic of conversation. The particle thì can be placed immediately after this fronted object to mark it, though it is optional and often dropped in spoken Vietnamese.

How It Works

To become proficient in natural Vietnamese discourse, understanding object fronting is essential. Here are the key rules:

  • Definite and Indefinite Topics: Fronted objects are overwhelmingly definite (e.g., "this book") or generic (e.g., "phở"). However, specific indefinite nouns and question words can also be fronted.
  • Resumptive Pronouns: When you move the object to the front, you can leave a gap, but Vietnamese frequently uses resumptive pronouns (like it) in the object's original position, especially in colloquial speech. However, be careful: using nó to refer back to a respected human object is highly offensive. Instead, you must use the appropriate respectful pronoun or kinship term (e.g., "ông ấy", "bà ấy", "người đó", "chị ấy").
  • Optional "Thì" and Pausing: While thì clearly marks the topic, it is optional. If omitted, you may use a pause (often written as a comma) after the fronted object, but this is not mandatory, especially for short, everyday sentences like "Cái áo này tôi mua hôm qua". Never confuse thì with the copula to be.
  • Question Words with "Cũng": When fronting a question word to mean 'any' or 'every' (e.g., 'cái gì'), you generally must use also in the comment clause.
  • Not a Passive Voice: Because the object comes first, English speakers often confuse this with the passive voice. However, object fronting is purely active. In Vietnamese, the 'Topic' (what the sentence is about) and the 'Subject' (the doer of the action) are two completely different grammatical slots. Fronting the object simply fills the Topic slot, leaving the Subject slot active. Even if you drop the subject in the comment clause (e.g., "Cái áo này mua hôm qua"), it remains an active sentence with an implied subject ("[Someone] bought this shirt yesterday"), even if it translates most naturally to an English passive. True passives require explicit markers like 'bị' or 'được'.
  • Natural Frequency: While sticking to SVO order is grammatically correct, avoiding object fronting makes your Vietnamese sound stiff. Natural discourse heavily relies on topic-comment structures.

Examples (4)

  1. Sách này, tôi đọc nó rồi.

    As for this book, I have already read it.

    Word by Word: Book this, I read it already.

    Notice the comma replacing "thì" to indicate a pause, and the natural use of the resumptive pronoun "nó" in the object's original position.

  2. Cái gì tôi cũng ăn.

    I eat absolutely anything.

    Word by Word: Thing what I also eat.

    When fronting a question word to mean 'anything' or 'everything', the adverb "cũng" is required before the verb.

  3. Phở thì tôi ăn rồi, còn cơm thì chưa.

    As for phở, I have already eaten it, but as for rice, not yet.

    Word by Word: Phở [topic] I eat already, whereas rice [topic] not yet.

    Demonstrates contrastive focus, a very common use of object fronting.

  4. Tiếng Việt thì tôi thích học.

    As for Vietnamese, I like studying it.

    Word by Word: Language Vietnamese [topic] I like study.

    Generic nouns like "tiếng Việt" can be fronted as topics.

Common Mistakes

  • Putting "thì" after the subject when you want to mark the fronted object as the topic.

    Different MeaningSách này tôi thì đọc rồi.
    Sách này (thì) tôi đọc rồi.

    'Sách này tôi thì đọc rồi' is a correct sentence, but thì after the subject adds a contrast ('as for me, I have read it'). To mark the fronted object as the topic with the optional particle thì, put it right after the object.

  • Forgetting "cũng" when fronting a question word.

    Cái gì tôi ăn.
    Cái gì tôi cũng ăn.

    When fronting a question word like "cái gì" (what) to mean "anything", you generally must include also before the verb in the comment clause.

Learn This First

To understand object fronting, you first need to be comfortable with standard Vietnamese word order. Since fronting an object effectively turns it into the 'topic' of the sentence, you must understand how Vietnamese uses the particle 'thì' to separate a topic from its comment, as well as the general concept of naming a topic at the start of a sentence.
