Classifier for Long Slender Things

Level 2

The word cây literally means "tree" or "plant", but it is also one of the most common classifiers in Vietnamese. It categorizes botanical plants and many inanimate objects that generally share a stick-like shape, though it extends to tools and musical instruments as well.

How It Works

While cây is naturally used for living plants (like cây chuối - banana tree), its use as a shape-based classifier is highly productive.

1. The Stick-Like Tendency
For inanimate objects, cây is generally used for items that are long and somewhat rigid, like a pen (cây bút) or an umbrella (cây dù). It is also used for very tiny stick-like objects, such as cây kim (a needle) and cây tăm (a toothpick), showing that scale does not matter as long as the shape fits. However, this is a strong tendency rather than a strict rule. It can also be used for items that are not perfectly rigid (like cây xúc xích - a sausage).

2. Tools, Weapons, and Instruments
Beyond simple stick shapes, cây is the standard classifier for many tools and weapons (cây búa - hammer, cây chổi - broom, cây súng - gun) and musical instruments like guitars and violins (cây đàn guitar, cây đàn violin). While you can say cây đàn piano, the classifier chiếc is equally or more common for large, furniture-like instruments.

3. Stick-Like Foods
You will also see it used for foods served on a stick or shaped like one, such as cây kem (popsicle/ice cream) or cây kẹo (lollipop).

4. Beyond Counting
Like all classifiers, cây is not just for numbers. You must use it when pointing to a specific object with words like này (this) or đó (that), even without a number: cây bút này (this pen).

5. Regional Differences
In Southern Vietnam, cây is strongly preferred for stick-like objects (cây viết). In Northern Vietnam, people often use the general classifier cái interchangeably for these items (cái bút). However, for weapons like guns, Northerners strongly prefer the specific classifier khẩu (khẩu súng) rather than cái.

6. Abstract Measurements
Interestingly, cây is also used for abstract measurements derived from stick-like objects, such as cây số (a kilometer, derived from milestone markers) or cây vàng (a tael of gold, derived from gold bars).

7. Standing Machines, Rolls, and Metaphors
In modern Vietnamese, cây is also used for tall, standing machines or structures like cây ATM (ATM) or cây xăng (gas pump/station). A fun modern example is cây máy tính (desktop computer tower), which originated as a phonetic loanword from the English 'case' but perfectly assimilated into the classifier cây because it stands upright like a pillar. It applies to fans (cây quạt), covering both standing fans and traditional handheld fans due to their stick-like handles. It is used for rolls or cylindrical packages like cây vải (a roll of fabric), cây chả or cây giò (a cylindrical roll of Vietnamese pork sausage), and cây thuốc lá (a carton of cigarettes). Metaphorically, it can even refer to people who are the main talent or pillar in a specific field, such as cây hài (a comedian) or cây văn nghệ (a key performer).

Examples (4)

  1. Tôi muốn mua một cây bút bi.

    I want to buy a ballpoint pen.

    Word by Word: I want buy one [classifier] pen ball.

    A classic example of 'cây' used for a long, rigid, inanimate object.

  2. Trong vườn có hai cây chuối.

    There are two banana trees in the garden.

    Word by Word: In garden have two [classifier] banana.

    Using 'cây' in its literal sense for botanical plants and trees.

  3. Cây dù này giá bao nhiêu?

    How much is this umbrella?

    Word by Word: [Classifier] umbrella this price how much?

    Notice how the classifier is required when using the demonstrative 'này' (this), even without a number.

  4. Nhà tôi cách đây khoảng năm cây số.

    My house is about five kilometers from here.

    Word by Word: House I distance here about five [classifier] number.

    'Cây số' is an abstract measurement for kilometers, originating from the stick-like milestone markers on roads.

Common Mistakes

  • Dropping the classifier when using numbers or demonstratives.

    Tôi có hai bút.
    Tôi có hai cây bút.

    In Vietnamese, you cannot attach a number directly to most nouns. You must use a counting frame with the appropriate classifier.

  • Using 'cây' for long but flexible objects.

    Cô ấy có một cây tóc bạc.
    Cô ấy có một sợi tóc bạc.

    While cây is generally for stick-like objects, it cannot be used for highly flexible, string-like items such as hair, thread, or noodles. For those, you must use classifiers like sợi or cọng.

Learn This First

To use the classifier 'cây', you first need to understand the general role of classifiers in Vietnamese noun phrases and how they fit into the standard counting frame (Number + Classifier + Noun). It is also helpful to understand the general classifier 'cái' to distinguish between general objects and those categorized by specific shapes like long, slender items.
