在 + Place (existence in a place)

• Pinyin: zài
• Formation: Subject + 在 + Place
• Hanzi breakdown: 在 = 土 (earth) + 才 (talent)

Meaning

The verb 在 (zài) expresses that someone or something exists or is located at a specific place. It is one of the most fundamental structures in Mandarin for expressing location.

When 在 is used as the main verb, it functions like 'to be at' or 'to be in' in English. The basic pattern is Subject + 在 + Place, expressing where something or someone is located. This is different from 有 which expresses what exists at a place (Place + 有 + Thing). A common point of confusion is that 在 can also function as a preposition before the verb to set the location of an action (我在图书馆看书), but as a main verb it simply states location. The negative form is 不在 (not at/not here).

Examples

1. 我的钥匙在桌子上。 My keys are on the table.
2. 他现在不在办公室。 He's not in the office right now.
3. 超市在医院的对面。 The supermarket is across from the hospital.
