HOW TO USE 在?

在 (zài) has several different uses and functions.

It can be used as a preposition and sometimes verb.

Most of them are related to location.

在 AS A PREPOSITION

When indicating the location that a verb takes place in, 在 (zài) followed by a location, comes before the verb.

PATTERN

Subject + 在 + Place + Verb

zài gōngsī gōngzuò.

公司工作。

He works in the company.
māmā zài chāoshì mǎi dōngxī.

妈妈超市买东西。

Mum is shopping in the supermarket.

NOTE – In English, location is usually put at the end of a sentence. In Chinese, location is usually put after the subject but before the verb.

  • ❌ 我学习在图书馆。wǒ xuéxí zài túshū guǎn
  • ✅ 我在图书馆学习。wǒ zài túshū guǎn xuéxí

However, there are some verbs that imply movement or location like 住 (zhù), 放 (fàng), 坐 (zuò), and 站 (zhàn), which can be put before the location.This structure “在 + Location” is called a location complement.
