Questions & Answers about i chinguneun haksaengieyo.

What does 이 mean in this sentence?

Here 이 is the demonstrative adjective meaning “this.” It points to someone (in this case, “friend”) who is close to the speaker.

Why do we say 친구 even though the English translation is “friend” but we often say “this friend”?

친구 alone means “friend.” In Korean you often specify proximity with 이 (“this”), 그 (“that” near the listener), or 저 (“that” far from both). Here 이 친구 means “this friend” (the person near the speaker).

What is the role of the particle 는 after 친구?

는 is the topic marker. It indicates that 친구 (“friend”) is what the sentence is about. In English you might render it as “As for this friend, (he/she)...” It can also give a slight contrast or emphasis depending on context.

Could we use 이 as a subject marker instead of 는?
