Classifier for Bottles

Level 1

Chai means 'bottle' and is used to count items contained in a bottle, such as water, beer, sauces, or even pills.

How It Works

In Vietnamese, classifiers are used to count things. While chai is actually a regular noun meaning 'bottle', it frequently acts as a temporary measure word to quantify liquids, sauces, and sometimes solids like pills.

1. Basic Structure
To order or count items in a bottle, use the standard counting frame: Number + Classifier + Noun.

  • một chai nước = one bottle of water
  • hai chai bia = two bottles of beer
  • một chai tương ớt = one bottle of chili sauce

2. Chai vs. Cái Chai
When measuring the contents, just use chai. If you add the general classifier cái (making it cái chai), you are talking about the physical bottle object itself (whether full or empty), not the liquid contents being measured.

3. Other Containers & Materials
Vietnamese uses different words depending on the container's shape and material:

  • Chai: Narrow-necked glass or plastic bottles for liquids and sauces. It is also commonly used for medicine/pill bottles (chai thuốc), especially in the South. (For aluminum cans, use lon).
  • Lọ: Smaller vials, wide-mouthed jars, or non-beverage containers (like pill bottles or vases in the North). Note: In Southern Vietnamese, lọ is rarely used; Southerners typically use hũ or keo for jars and vials, and bình for vases.
  • Bình: Larger jugs, pitchers, or thermoses.

4. Slang Note
In everyday shopping contexts, especially in the South, chai is commonly used as slang for one million VND (e.g., hai chai = two million VND). In the North, the equivalent slang term is củ (e.g., hai củ = two million VND).

  1. Tôi mua một chai nước.

    I bought a bottle of water.

    Word by Word: I buy one bottle water.

    The most common everyday use of 'chai' to buy a drink.

  2. Anh ấy uống hai chai bia.

    He drank two bottles of beer.

    Word by Word: He drink two bottle beer.

    Notice that 'chai' does not change form or become plural when the number increases.

  3. Cho tôi một chai nước mắm.

    Give me a bottle of fish sauce.

    Word by Word: Give me one bottle water fish-sauce.

    Used for ordering or requesting items in a store or restaurant.

  4. Nhà tôi còn ba chai rượu.

    My house still has three bottles of liquor.

    Word by Word: House my still three bottle liquor.

    Used to quantify inventory or possessions.

Common Mistakes

  • Adding 'cái' when you mean a bottle of water to drink.

    Different MeaningTôi muốn một cái chai nước.
    Tôi muốn một chai nước.

    'Một cái chai nước' is a correct phrase, but it names the container (a water bottle). When chai measures the liquid, it acts as the measure word itself: 'một chai nước' is a bottle of water. Drop cái when you mean the contents.
