They look simple, but they’re the #1 grammar challenge for Chinese learners. Why? Because Chinese doesn’t have tenses like English—instead, it uses these particles to show how actions relate to time.

In this guide, I’ll show you exactly when to use each particle with clear rules and real examples. By the end, you’ll know which particle to use—every time.

Why Chinese Particles Matter

Before diving into each particle, let’s understand why they exist.

English changes verbs to show time:

• I eat (present)
• I ate (past)
• I am eating (ongoing)
• I have eaten (experience)

Chinese verbs never change. Instead, you add particles:

• 我吃 (I eat)
• 我吃了 (I ate / completed eating)
• 我吃着 (I’m eating / in the process)
• 我吃过 (I’ve eaten before / have the experience)

Same verb (吃), different meanings!

If you’re still struggling with basic sentence structure, review my Chinese sentence structure guide first.

了 (Le): Completion and Change

了 (le) is the most common particle—and the most confusing because it has TWO different uses.

Use #1: 了 After Verbs (Completion Marker)

Pattern: Verb + 了 + Object

This shows an action is completed.

Examples:

Key point: This 了 shows the action is done and finished.

Use #2: 了 at Sentence End (Change of State)

Pattern: Subject + Verb + Object + 了

This shows a new situation or change has occurred.

Examples:

Key point: This 了 announces “something is now true that wasn’t before.”

When to Use BOTH 了’s (Double 了)

Sometimes you need both!

Pattern: Verb + 了 + Object + 了

This means an action was completed AND it’s a new situation.

Examples:

Think of it as: First 了 = completed action, Second 了 = new situation

How to Negate 了 Sentences

Use 没 (méi) instead of 不:

Important: When you use 没, you drop the 了!

着 (Zhe): Ongoing Actions and States

着 (zhe) shows something is in progress or in a continuing state.

Think of it like the -ing form in English.

Use #1: Continuous Actions

Pattern: Verb + 着

Examples:

Use #2: Simultaneous Actions

Pattern: Verb1 + 着 + Verb2

This shows two actions happening at the same time.

Examples:

Pattern meaning: “While doing [Verb1], also doing [Verb2]”

Use #3: Describing States

Use 着 to describe how something looks or what state it’s in:

Examples:

How to Negate 着 Sentences

Use 没 (méi) + Verb + 着:

过 (Guo): Past Experience

过 (guo) means “have done something before” or “have the experience of”.

It’s like English “have been to” or “have tried.”

Expressing “Have Done”

Pattern: Subject + Verb + 过 + Object

Examples:

Key point: 过 focuses on whether you have the experience, not when it happened.

Common Patterns with 过:

1. Asking about experience:

你去过中国吗?
Have you been to China?

你吃过日本菜吗?
Have you tried Japanese food?

2. With 从来没 (never):

我从来没去过美国
I’ve never been to America

他从来没吃过这个
He’s never tried this

过 vs 了: What’s the Difference?

This is where learners get confused! Here’s the key difference:

Think of it this way:

• 了 = “I did it” (specific action, often recent)
• 过 = “I’ve done it” (have the experience, time not important)

How to Negate 过 Sentences

Use 没 (méi) + Verb + 过:

Important: Unlike 了, you keep the 过 when negating!

Quick Comparison: 了 vs 着 vs 过

Same Verb, Different Particles:

Let’s use the verb 吃 (eat):

• 我吃了饭 = I ate (finished eating)
• 我吃着饭 = I’m eating (in the middle of eating)
• 我吃过这个菜 = I’ve tried this dish (before)

Common Mistakes to Avoid

❌ Mistake #1: Using 了 for Experience

Wrong: 我去了中国 (when you mean “I’ve been to China before”)
Right: 我去过中国

Why: 了 sounds like you just went to China recently, not “have been there before”

❌ Mistake #2: Using 着 for Completed Actions

Wrong: 我吃着饭了 (when you mean “I finished eating”)
Right: 我吃了饭

❌ Mistake #3: Dropping 了 When Negating

Wrong: 我没吃了饭
Right: 我没吃饭 (no 了 with 没!)

❌ Mistake #4: Using 不 Instead of 没

Wrong: 我不吃了饭
Right: 我没吃饭

Remember: Use 没, not 不, to negate 了 and 过!

❌ Mistake #5: Dropping 过 When Negating

Wrong: 我没去中国
Right: 我没去过中国

Why: Without 过, it sounds like you’re talking about a specific recent trip
