Vietnamese classifiers: cái, con, chiếc and when to use them
Updated · By the Chào team
What are classifiers in Vietnamese?
A classifier is a small word placed between a number (or "this/that") and a noun: hai con mèo (two cats), một cái bàn (one table). Vietnamese cannot go straight from a number to a noun. Con is used for animals, cái for most objects, and a few others for specific shapes.
The pattern
Number + Classifier + Noun — ba cái áo (three shirts), một con chó (one dog).
The same slot is used with "this" and "that": cái bàn này (this table), con mèo kia (that cat over there).
The classifiers you need first
| Classifier | Used for | Example |
|---|---|---|
| cái | most objects | một cái ghế — a chair |
| con | animals, some living things | hai con cá — two fish |
| chiếc | vehicles, single items of a pair | một chiếc xe — a vehicle |
| quyển / cuốn | books | ba quyển sách — three books |
| tờ | sheets of paper, newspapers | một tờ báo — a newspaper |
| quả / trái | fruit, round things (north / south) | một quả cam — an orange |
| người | people | hai người bạn — two friends |
When you can drop the classifier
Some nouns are counted directly because they are units themselves: hai ngày (two days), ba năm (three years), năm phút (five minutes). If you are unsure, cái is the safest default for objects and con for animals.
Frequently asked questions
Is it wrong to say "hai mèo" without con?
Yes — native speakers always say hai con mèo. Leaving out the classifier sounds as odd as "two breads" does in English.
