TL;DR
- -아/어지다 attaches to adjectives to show that something becomes or changes into that state 🔄
- It's like adding "-er" in English (get bigger, get colder) and follows the same 아/어 vowel harmony rules you already know 🎵
- This pattern turns descriptive words into action words, showing transformation over time ✨
What is -아/어지다? 🤔
This grammar pattern is all about change and transformation! 🦋
When you attach -아/어지다 to an adjective, you're saying that something is becoming or getting that way. It's the difference between "it's cold" (춥다) and "it's getting cold" (추워지다) ❄️
Think of it as the magic spell that turns states into changes! ✨
How to Form It 🔨
Follow the regular 아/어 vowel harmony rules you already know! 🎶
Step 1: Drop -다 from the adjective
Step 2: Add -아지다 or -어지다 based on the last vowel
- ㅏ or ㅗ vowels → -아지다 🟠
- All other vowels → -어지다 🔵
- 하다 adjectives → -해지다 💜

Common mistakes
- 🚫 Forgetting to attach -아/어지다 to the stem: Don't say "좋다졌어요" — remove 다 first and use "좋아졌어요"
- 🚫 Using -아/어지다 with action verbs: This grammar is for changes in state, not actions like "먹다" or "가다"
- 🚫 Mixing up -아지다 and -어지다: Stems with 아/오 vowels take -아지다 (맑아지다), while others take -어지다 (쉬워지다)
- 🚫 Confusing with passive voice: -아/어지다 shows change, not passive meaning — "문이 열어졌어요" means the door became open (changed state), not that it was opened by someone
