Welcome everybody to the 2nd lesson of Level 5. In this lesson we are going to introduce how the honorific suffix -시- [-si-] is used in “politer” and “more formal” situations. Even if this is the first time you have heard about this “honorific suffix”, you probably have already seen some expressions before that have this word -시- in them, such as 안녕하세요, 안녕히 가세요 or 주세요. Thank you for studying Korean with us!! Enjoy!
