Learning Objective
Choose five essential Korean particles from the role and meaning of the noun.
Quick Summary
Particles attach to nouns and show how those nouns function in a sentence. Choose from meaning and context, not from English word order alone.
Use this cheat sheet as a review tool after reading the main explanation. A cheat sheet should help you recall a pattern quickly, but it should not replace examples, pronunciation practice, or writing practice. Read each Korean form aloud, check the usage note, and then make one short sentence of your own before moving to the next item.
Core Information
| Korean | Romanization | Meaning | When to use | Example |
|---|---|---|---|---|
| 은/는 | eun/neun | topic or contrast | 은 after consonant; 는 after vowel | 저는 학생이에요. |
| 이/가 | i/ga | focused subject | 이 after consonant; 가 after vowel | 친구가 와요. |
| 을/를 | eul/reul | object of an action | 을 after consonant; 를 after vowel | 물을 마셔요. |
| 에 | e | destination, time, static location | place or time + 에 | 학교에 가요. |
| 에서 | eseo | place of action; starting point | place + 에서 + action | 학교에서 공부해요. |

Grammar Connection
A particle cannot be chosen from the noun alone. Read the full predicate: 가요 needs a destination with 에, while 공부해요 needs the place of an action with 에서.
Pronunciation Tips
Particles attach to the preceding noun as one rhythmic unit. Avoid stressing them like separate English words.
Native Speaker Note
Particles are sometimes omitted in conversation when the relationship is obvious. Keeping them is natural when clarity, focus, or contrast matters.
Native usage notes are included because beginners often learn a dictionary meaning first and later discover that the word or pattern is used more narrowly in real conversation. Pay attention to the situation, politeness level, and relationship described in the notes.
Common Mistakes
- Using 에서 with a destination verb such as 가다
- Treating 은/는 and 이/가 as always interchangeable
- Choosing 을/를 without checking whether the verb takes an object
Memory Hacks
- Topic sets the frame: 은/는.
- Subject answers who or what: 이/가.
- Action hits an object: 을/를.
- Go to 에; do at 에서.
Culture Note
Politeness is carried mainly by sentence endings and word choice, not by particles alone. A correctly marked sentence can still be casual or polite depending on its ending.
Quick Review Challenges
The review tasks below are short on purpose. A quick-reference page works best when it sends you back into active recall: covering the English, choosing a Korean form, saying a model sentence, and checking whether your choice matches the situation.
30 Second Review

Self Check
Teacher Notes
- Use identical nouns with different predicates to demonstrate 에 and 에서.
- Ask learners to justify each particle before checking the answer.
- Level: beginner; suggested lesson use: 15 minutes.
Teachers can use the page as a warm-up, exit ticket, or review station. Ask learners to explain why one form fits a sentence instead of only copying the answer. This keeps the cheat sheet connected to understanding rather than passive memorization.
Extension Activity
Rewrite two sentences by changing the topic or place, then explain which particle must change and why.

Frequently Asked Questions
Can Koreans omit particles?
Yes when context makes the role obvious, especially in relaxed conversation. Beginners should first learn the complete form.
What is the hardest particle contrast?
Many beginners find 은/는 versus 이/가 and 에 versus 에서 difficult because both choices can relate to the same noun while changing information focus or function.
