Welcome to the World of 介词 (Prepositions)!

Hello! Today, we are diving into a small but mighty group of words in Chinese called 介词 (jiècí), or prepositions. If a sentence were a piece of furniture, prepositions would be the screws and glue that hold everything together. They help us explain where, when, how, and with whom an action happens.

Don’t worry if Chinese grammar feels a bit "backwards" compared to English sometimes. By the end of these notes, you’ll see that Chinese prepositions follow some very logical patterns. Let’s get started!

1. What Exactly is a 介词?

In Chinese, a 介词 is a word that sits in front of a noun or a pronoun to create a "prepositional phrase." This phrase then gives more detail to the main verb of the sentence.

The Golden Rule: A 介词 almost never stands alone. It always needs a "partner" (a noun or pronoun) to make sense.
Example: You wouldn't just say "I from." You say "I from London (came)."

The "Bridge" Analogy

Think of a 介词 as a bridge. One side of the bridge is a person or object, and the other side is the action. The bridge tells us how they relate to each other.

2. The Most Important Rule: Word Order

This is where many students get tripped up! In English, we often put the prepositional phrase after the verb. In Chinese, we usually put it BEFORE the verb.

English Style: I eat at home.
Chinese Style: I at home eat. (我在家吃饭。)

The "Sentence Sandwich" Formula:
Subject + [Preposition + Object] + Verb + Everything else

Quick Review:

If you want to say "I study with my friend," remember to move the "with my friend" part to the front of "study":
我 (Subject) + 和朋友 (Prep Phrase) + 学习 (Verb)。

3. Common Types of 介词

To make them easier to remember, we can group prepositions into "families" based on what they do.

A. The "Time and Place" Family

These tell us where or when something is happening.

  • 在 (zài): At / In / On. (Example: 我在学校。 I am at school.)
  • 从 (cóng): From. (Example: 我从北京来。 I come from Beijing.)
  • 到 (dào): To / Until. (Example: 我学到五点。 I study until 5 o'clock.)
  • 离 (lí): Away from (used for distance). (Example: 我家离超市很近。 My house is close to the supermarket.)

B. The "Direction and Target" Family

These tell us who we are talking to or which way we are going.

  • 对 (duì): To / Towards (often used for attitudes). (Example: 老师对我很好。 The teacher is good to me.)
  • 向 (xiàng): Towards. (Example: 向前走。 Walk towards the front/Forward.)
  • 给 (gěi): For / To. (Example: 我给你打电话。 I will give you a phone call/Call you.)
  • 跟 (gēn) / 和 (hé): With. (Example: 我跟他去商店。 I go to the store with him.)

C. The "Reason and Basis" Family

These explain why or how something is done.

  • 为 (wèi) / 为了 (wèile): For / For the sake of. (Example: 为了健康，我们要运动。 For the sake of health, we must exercise.)
  • 根据 (gēnjù): According to. (Example: 根据天气预报... According to the weather forecast...)
  • 用 (yòng): Using / With (a tool). (Example: 我用筷子吃饭。 I eat using chopsticks.)

4. Two "Special" Prepositions You Must Know

In the AQA syllabus, you will often see 把 (bǎ) and 被 (bèi). Even though they have their own special sentence structures, they are technically 介词!

1. 把 (bǎ): Focuses on what happened to the object. (Example: 我把作业写完了。 I finished the homework.)
2. 被 (bèi): Used for passive voice. (Example: 苹果被我吃了。 The apple was eaten by me.)

Did you know? Many words that are 介词 (prepositions) today actually started as 动词 (verbs) in ancient Chinese! For example, 在 originally meant "to exist" and 用 meant "to use." This is why they still sit in the "action" part of the sentence.

5. Common Mistakes to Avoid

Mistake 1: Mixing up "对" (duì) and "给" (gěi).
Use 对 when you are expressing an attitude or target (e.g., "I am interested in...").
Use 给 when you are doing a favor or providing a service (e.g., "I buy a gift for him").

Mistake 2: Putting the preposition at the very end.
Incorrect: 我去学校和朋友。(English style)
Correct: 我和朋友去学校。(Chinese style)

6. Summary & Key Takeaways

Key Points to Remember:

  • Position: Place the prepositional phrase BEFORE the verb.
  • Partnership: A preposition always needs a noun or pronoun following it.
  • Function: They provide context like time, place, method, or target.
  • Memory Trick: Think of the "Who + Where/How + Do" logic. (I + with friend + go).

Don't worry if this seems tricky at first! The more you read Chinese texts, the more you will notice these "bridges" appearing before the verbs. Try writing three simple sentences about your day using 在, 跟, and 为 to practice!
