내일 (tomorrow)
@yanie You have to use the previous word to make a new one. ^^' Like  어 (word)

I'll use yours then: 하다
시금치 (Spinach)
치료 (treatment)
치약 toothpaste
약속 - promise

I so love this thread. 
속눈썹 (eyelashes)
써비스 (service) The free side dishes you get in a Korean restaurant, or basically anything they say is service is free in a restaurant

There is no word that starts with 썹 so I pulled it apart, it sounds very similar though
다 [multiple meanings; 1) to take or record; e.g. 사진을 찍다 // take a picture]
