Nobody pushed it, the dial moved on its own: -아/어지다

Where the picture shows up in -아/어지다

1. 1

   the dial that slid by itself

   요즘 날씨가 많이 추워졌어요.

   yo-jeum nal-ssi-ga ma-ni chu-wo-jyeo-sseo-yo

   It's gotten a lot colder lately.

   On an adjective it stops meaning 'is that way' and starts meaning 'is becoming that way': 춥다 (cold) → 추워지다 (get cold).

2. 2

   a slow drift into place

   한국 생활이 이제 익숙해졌어요.

   han-guk saeng-hwa-ri i-je ik-su-kae-jyeo-sseo-yo

   I'm used to life in Korea now.

3. 3

   an accident with the hand erased

   설거지하다가 컵이 깨졌어요.

   seol-geo-ji-ha-da-ga keo-bi kkae-jyeo-sseo-yo

   A cup broke while I was washing up.

   컵을 깨뜨렸어요 = I broke it; 컵이 깨졌어요 = it broke. The weight of blame is completely different.

4. 4

   it just works

   이 펜은 잘 써져요.

   i pe-neun jal sseo-jyeo-yo

   This pen writes well.

5. 5

   a decision nobody signs

   회의가 다음 주로 미뤄졌어요.

   hoe-ui-ga da-eum ju-ro mi-rwo-jyeo-sseo-yo

   The meeting has been pushed to next week.
