Questions & Answers about uri samusireun 3cheunge isseoyo.

Why isn’t there a particle immediately after 우리?

Because 우리 사무실 is treated as one noun phrase where 우리 serves as a determiner (“our”) modifying 사무실 (“office”). You only need a topic marker (은) on 사무실, not on 우리 itself.

What does the particle 은 do in 사무실은?

은 marks 사무실 as the topic of the sentence. It highlights “our office” as what you’re talking about. Note that if a noun ends in a vowel you’d use 는 instead, but because 사무실 ends in a consonant (ㄹ), you attach 은.

Why is it 3층 and not using native Korean numbers?

Korean floors almost always use Sino-Korean numbers (일, 이, 삼, …) plus 층. So “third floor” is 삼층, often written with a digit as 3층. Native Korean numbers (like 하나, 둘) aren’t normally used with 층.

What role does the particle 에 play in 3층에?

에 is the location particle indicating where something exists or happens. Here, 3층에 means “on the third floor,” marking the place where the office is.

How does 있어요 work in this sentence?
