MANDARIN SENTENCE PATTERN
Numbers and classifiers
Count people and objects with an appropriate measure word.
Number + classifier + noun
A number normally needs a classifier before the noun. 个 is common for people and many objects, 本 for books, and 杯 for cups or glasses of a drink.
两 commonly means two before a classifier. 二 is used in counting and numbers such as 十二. Learn classifiers with their nouns.
Examples
我有两本书。
I have two books.
我要一杯茶。
I would like a cup of tea.
三个学生在这里。
Three students are here.
Keep in mind
个 is useful but does not replace every classifier. In 一杯 the spoken tone of 一 is fourth tone.
