피동

TL;DR

  • 피동 (passive verbs) are created by adding 이/히/리/기 to certain verb stems to shift focus from "who does" to "what gets done" 🔄
  • Not all verbs can become passive this way—only specific verbs work with these suffixes, and you'll need to memorize which suffix goes with which verb 📚
  • Korean uses passive voice much less than English, so when in doubt, stick with active voice! 💪

What Are Passive Verbs? 🤔

In Korean, passive verbs let you flip the focus of a sentence 🔄
Instead of saying "I opened the door" 🚪, you can say "The door was opened"—shifting attention from the doer to the thing being done to ✨
Korean creates these passive verbs by adding special suffixes to certain verb stems: 이, 히, 리, or 기 🎯

The Four Passive Suffixes 🔤

Here's how they work! 💡
-이
문이 닫히다 (the door is closed)
책이 읽히다 (the book is read)
-히
문제가 풀리다 (the problem is solved)
신발이 벗기다 (shoes are taken off)
-리
소리가 들리다 (sound is heard)
모습이 보이다 (a figure is seen)
-기
옷이 벗기다 (clothes are taken off)
밥이 먹히다 (food is eaten)

How to Use Them 📝

음악 소리가 들려요 (Music sound is heard)

Important Notes! ⚠️

You can't just add these suffixes to any verb 🚫
Only certain verbs accept passive forms with 이/히/리/기—there's no clear pattern, so you'll need to learn them one by one 📖
❌ 가다 → 가이다 (doesn't exist!)
❌ 오다 → 오이다 (nope!)
Korean uses passive voice WAY less than English 🇰🇷
What sounds natural in English might sound awkward in Korean 😅
When unsure, use active voice instead! 💪

Exceptions 🌈

Some passive verbs have irregular meanings 🎭
먹히다 can mean "be eaten" OR "work/be effective" (as in 말이 안 먹혀 = that won't work)
쓰이다 can mean "be written" OR "be used"
Some verbs use -되다 instead 🔄
Many verbs form passives with -되다 rather than these suffixes (that's a different grammar point!) 🎯
만들다 → 만들어지다 (be made)
사용하다 → 사용되다 (be used)

You've got this! 🎉 Start by learning the most common pairs, and you'll naturally pick up which verbs take which suffix over time 🌱✨

Common mistakes
  • 🚫 Don't forget that not all verbs can become passive with 이/히/리/기—only specific verbs work with this pattern.
  • 🚫 Remember that the subject of a passive sentence is what receives the action, so particles change (을/를 → 이/가).
  • 🚫 Be careful not to confuse passive verbs with their active counterparts—context matters!
  • 🚫 Watch out for irregular sound changes when adding 이/히/리/기 (e.g., ㄹ dropping in some cases).
