Grammar · Politeness
-(으)시-, the honorific
Pattern
[stem] + 시 / 으시 + ending
-(으)시- goes inside the verb to show respect to the person doing the action. With the -요 ending it becomes -(으)세요 (가세요), in the past -(으)셨어요 (가셨어요), and in the future -(으)실 거예요. Use it about older people, strangers, customers and anyone senior to you.
The mistake to avoid
Never use it about yourself. 저는 가세요 is wrong; respect goes to the other person, so you say 저는 가요.
