Chinese does not say "two people" directly. It says "two [classifier] people" - 两个人 liǎng ge rén - with the classifier 个 inserted between number and noun. Measure words (量词 liàngcí), also called classifiers, are obligatory in Chinese whenever you count nouns, specify a particular instance with demonstratives (this/that), or ask "how many." Every countable noun has a preferred classifier, and using the right one is a mark of fluent speech. English has some classifiers too ("a head of cattle," "a slice of bread"), but Chinese uses them for nearly all nouns.
This reference organizes the most common classifiers by the type of noun they pattern with, explains the grammar of classifier phrases, and gives detailed notes on usage. For beginner-level introduction, see the Chinese measure words complete guide. For related grammar see the Chinese grammar rules guide. For pronunciation of these classifiers, see the pinyin complete guide.
The Classifier Structure
The basic pattern:
Number/Demonstrative + Classifier + Noun
Examples:
- 一个人 yí ge rén - one person
- 三本书 sān běn shū - three books
- 这条鱼 zhè tiáo yú - this fish
- 那张桌子 nà zhāng zhuōzi - that table
You cannot drop the classifier. *一人 (yī rén) is ungrammatical for "one person" in standard Mandarin.
The Universal Classifier: 个 (ge)
个 gè (usually pronounced ge with neutral tone) is the default classifier, used when you don't know or can't recall the specific one. It works for people (人 rén), objects generally (东西 dōngxi), and many abstract concepts.
- 一个人 one person
- 两个苹果 two apples
- 三个问题 three questions
Using 个 everywhere is comprehensible but sounds childish or non-native. Native speakers prefer the specific classifier whenever there is one.

Verbal Classifiers
Some classifiers count verb actions, not nouns:
- 看一次 kàn yí cì - see once
- 吃一口 chī yì kǒu - take one bite
- 说一遍 shuō yí biàn - say one time through
- 看一眼 kàn yì yǎn - take one look (eye)
These go after the verb: Verb + Number + Classifier + (Noun).
Classifier + Noun Without a Number
After 这 (this) or 那 (that), the number 一 (one) is usually dropped:
- 这本书 zhè běn shū (this book)
- 那个人 nàge rén (that person)
In plural form:
- 这些书 zhè xiē shū (these books)
The classifier still appears - it is the number that can be omitted.
Two: 二 vs 两
二 èr is the counting numeral "two." 两 liǎng is the quantity "two (of)." When counting with a classifier, use 两:
- 两个人 liǎng ge rén (two people)
- 两本书 liǎng běn shū (two books)
- 两点钟 liǎng diǎn zhōng (2 o'clock)
二 is used in:
- Counting sequentially: 一, 二, 三
- Telephone numbers
- Ordinals: 第二 (second)
- Decimals, fractions: 二分之一 (one half)
Wrong: *二本书; right: 两本书.
Common Mistakes Learners Make
- Dropping the classifier. "Two people" must be 两个人, not *两人 (though 两人 can be a literary shortening).
- Using 二 instead of 两 with classifiers. *二本书 is wrong.
- Overusing 个 for everything. Comprehensible but not fluent. Learn the right classifier for each noun.
- Using 条 for all long things. 条 is for flexible long items (rivers, pants, fish). Rigid long items take 根 or 支.
- Confusing 位 and 个. 位 is honorific - reserve for respected persons.
- Forgetting 双 and 对. Pairs use 双 (shoes, chopsticks) or 对 (couple, earrings).
- Mixing 次 and 遍. 次 counts occurrences; 遍 emphasizes completing the entire thing each time.
- Misusing 件 for lower garments. 件 is for upper clothing; 条 for pants and skirts.

FAQ
Do I really have to memorize a classifier for every noun?
You should memorize it for the most common nouns. When you don't know a specific classifier, 个 is the safe default and will always be understood.
Why does Chinese need classifiers at all?
Classifiers historically specified the shape or category of the noun. They survive because they make the number more precise and reflect long-standing structural grammar.
Can I invent a classifier?
Generally no. There are conventional pairings. But some nouns accept multiple classifiers with different shades of meaning.
How many classifiers are there total?
Hundreds exist in dictionaries, but about 40-50 cover 95 percent of daily use. HSK lists about 30 at levels 1-3.
What happens with "two hours" - 两个小时 or 二小时?
两个小时 (two hours) uses 两 because it is a quantity. 两小时 (without 个) is also acceptable since 小时 functions partly as a classifier itself.
Is "how many" asked with a classifier?
Yes. 你有几本书？(nǐ yǒu jǐ běn shū) - how many books do you have? The classifier stays.
Do verbal classifiers also require specific forms?
Yes. Common ones are 次, 遍, 趟, 下 (for quick actions), 口 (for bites), 眼 (for looks). Each has a specific flavor.

Frequently Asked Questions
Do I have to memorize a classifier for every noun?
For common nouns, yes. When you don't know a specific one, 个 is a safe default and will be understood, although it sounds less polished.
Why does Chinese need classifiers?
Historically classifiers specified the shape or category of nouns. They remain in modern usage as a grammatical requirement for counting and specifying.
Can I invent a classifier?
No. Classifier-noun pairings are conventional. Some nouns accept more than one classifier with different nuances.
How many classifiers are there?
Hundreds exist, but roughly 40-50 cover 95 percent of daily use. HSK 1-3 include about 30.
Is 两小时 without 个 acceptable for two hours?
Yes. 小时 partly functions as a classifier itself, so both 两个小时 and 两小时 are acceptable.
How do I ask 'how many' with a classifier?
Use 几 plus the classifier: 你有几本书 (how many books do you have?).
Do verbal classifiers exist?
Yes. Common verbal classifiers include 次, 遍, 趟, 下, 口 (for bites), and 眼 (for glances). Each has a distinct nuance.
