### Formal vs Casual {#formal}

There are two ways of communicating in Korean

존댓말 - formal one. More polite, good `default` mode.
반말 - informal one - to be used with friends

Usually the difference is adding -요 to the end. Also, if there are many ways of saying/writing something, the longer one is more polite one.

### What {#what}

###### What + verb -> 뭐 + verb
example: 뭐 했어요? -> What did you do?

###### What + noun = what kind of -> 무슨 + noun
example: 무슨 책 좋아해요? - what kind of books do you like?

### Time {#time}

AM = 오전
PM = 오후
hour = 시
minutes = 분

time format: 오전/오후 + NK number + 시 + SK number + 분

year = 년 
month = 월
day = 일

date format: SK + 년 + SK + 월 + SK + 일

### Counting {#counting}

what + NK number + counting word

|마리|animal|can't use 개|
|병|bottle||
|벌|clothes||
|개|"thing"|can be used for other words unless specified otherwise|
|그루|tree||
|켤레|a pair||
|장|paper, page, ticket|also works for e-tickets|
|권|book||
|대|car, phone, tv|from what I understand "expensive" things|
