Verb + nổi

Manage the Effort

Level 4

The particle nổi attaches to a verb to indicate capacity—specifically physical stamina, mental endurance, or financial ability. It is most frequently used in negative sentences to express that a task is too physically exhausting, emotionally overwhelming, or expensive to manage.

How It Works

Structure:

  • Affirmative: Verb + nổi (e.g., Tôi vác nổi). Note that this form is rarely used as a standalone statement out of the blue; it is almost exclusively used to answer a nổi không? question or to express surprise at someone's capacity. The short answers to a nổi không? question are simply nổi (yes) or không nổi (no).
  • Negative: There are two interchangeable structures. The formal/written preference (and more common in the North) is không + Verb + nổi (e.g., không vác nổi), while the universal spoken standard across all regions is Verb + không + nổi (e.g., vác không nổi).
  • Exhausted Capacity: To express "cannot [Verb] anymore," indicating that your capacity was there but has just run out, you can add nữa to the negative structure: không + Verb + nổi + nữa (e.g., không chịu nổi nữa). Alternatively, replacing không with hết creates Verb + hết + nổi (e.g., chịu hết nổi), which is very common in casual speech.
  • Interrogative: Verb + nổi không? (e.g., Bạn vác nổi không?)
  • Object Placement: When using a transitive verb, the object can be placed after the entire phrase (e.g., Tôi vác không nổi cái bàn này), between the verb and the negative phrase (e.g., Tôi vác cái bàn này không nổi), or topicalized at the beginning of the sentence (e.g., Cái bàn này tôi vác không nổi).

Common Use Cases:

  • Physical Capacity: Lacking strength or stamina (e.g., vác không nổi - cannot carry, ăn không nổi - too full to eat).
  • Mental/Emotional Capacity: Being overwhelmed by stress or cognitive load (e.g., chịu không nổi - cannot bear it, nhớ không nổi - cannot remember because there is too much information).
  • Financial Capacity: Lacking the funds to afford something (e.g., mua không nổi - cannot afford to buy, trả không nổi - cannot afford to pay).

Nuance & Comparisons:
Learners often confuse nổi with được, xuể, or kịp.

  • nổi vs. được: được refers to general possibility or external conditions. Tôi ăn không được means "I can't eat it" (due to allergies, spice, or rules). Tôi ăn không nổi means "I can't manage to eat it" (because you lack the physical capacity due to being too full, sick, exhausted, or disgusted).
  • nổi vs. xuể vs. kịp: xuể refers strictly to quantity or volume (làm không xuể = too much work to finish). kịp refers to time (làm không kịp = not enough time). nổi means the task exceeds your physical, mental, or financial capacity (làm không nổi = too difficult or exhausting).

Register & Region:
This pattern is extremely common in everyday spoken Vietnamese nationwide. A highly common phrase to become confident with is chịu không nổi (I can't stand/bear it anymore). While often associated with Southern slang (where you might hear hổng nổi or chịu hết nổi), it is standard across all regions and is an essential part of natural communication.

    There's too much pressure, I can't bear it anymore!

    Word by Word: Much pressure too, I bear finished manage already!

    Demonstrates mental and emotional exhaustion. Note that 'hết' (finished/out of) is often used instead of 'không' for strong emphasis.

  4. Nhiều từ vựng quá, tôi nhớ không nổi.

    There is too much vocabulary, I can't manage to remember it all.

    Word by Word: Much vocabulary too, I remember not manage.

Common Mistakes

  • Using 'được' instead of 'nổi' when turning down food because you are full, sick, or disgusted.

    Tôi no quá, tôi ăn không được nữa.
    Tôi no quá, tôi ăn không nổi nữa.

    Saying 'ăn không được' implies there is something wrong with the food itself (e.g., it tastes bad, is too spicy, or violates a dietary restriction). To say you lack the physical capacity to continue eating (because you are too full, sick, exhausted, or disgusted), you must use 'nổi'.
