Necessary Vocabulary

Things The Mouse has learned by necessity:

(Thanks to Sung, JK, and Jennifer for most of these.)

police station - 경찰서 gyeongchalseo
trash bag - 쓰레기 봉투 sseuregi bongtu
plastic bag - 비닐 봉투 binil (vinyl) bongtu
recycling bag 재활용 봉투 jaehwal-yong bongtu
give me... 주 세유 juseyo (as in, sseuregi bongtu juseyo - give me a trash bag. Also, no, this is not rude, regardless of its lack of "please.")

The end consonant for 1-4 and 20 (seumul) drops when next to a consonant. For example, when you order in a restaurant, you might say "2 (things)" which becomes "du gae" or if you're ordering samgyeopsal for three people, for example, it's "se  samgyeopsal." I've also heard "sa" used more for "four" than "net." "Sa" is the Sino-Korean "four," which is usually only used for ordinal numbers, rather than cardinals, though the distinction is not that clear-cut, since they're also used for some forms of measurement, among other things. I think it is often used in place of the Native Korean for 4 however, because number 4 is bad luck.)
