Korean politeness levels
I am just reading a Korean grammar book and it explains that there are five levels of politeness in Korean language, three informal levels and two formal levels.
1st level: -아/어
2nd level: -다,는/ㄴ다
3d level: -네
4th level: -아요/어요
5th level: -습/ㅂ니다
Very unfortunately, this book lacks a table of these forms for at least some examples.
Would you be so very kind to give me the five forms for the following two verbs? 하다 and 이다
