Done, and left where it lies: -아/어 두다

Where the picture shows up in -아/어 두다

1. 1

   done in advance

   식당은 미리 예약해 뒀어요.

   sik-dang-eun mi-ri ye-ya-kae dwo-sseo-yo

   I already booked the restaurant.

2. 2

   left in that state

   창문 좀 열어 둘까요?

   chang-mun jom yeo-reo dul-kka-yo

   Should I leave the window open?

3. 3

   written down and kept

   주소는 제가 적어 둘게요.

   ju-so-neun je-ga jeo-geo dul-ge-yo

   I'll write the address down for later.

4. 4

   piled up and kept aside

   비상금을 조금 모아 뒀어요.

   bi-sang-geu-meul jo-geum mo-a dwo-sseo-yo

   I've put a little emergency money aside.

5. 5

   놓다, the same picture

   남은 반찬은 냉장고에 넣어 놓으세요.

   na-meun ban-cha-neun naeng-jang-go-e neo-eo no-eu-se-yo

   Put the leftovers in the fridge and leave them there.

   두다 leans toward keeping it for a long while, 놓다 toward just getting it done. They are nearly interchangeable.
