"This desk is big."

Translation: 이 책상이 큽니다.

[xMira_]

Is the "this" there just to make it specific instead of just "desk is big"?

[habibaellamey]

Yeah I think that so.

[JoeNace]

I'm confused by the 이 being both before and after 책상. I'm a beginner so maybe I'm missing something obvious.

[ArabicMusi]

The first one means "this" and yhe second one has no meaning its "the subject marking particle" used to make the subject more obvious to the listener

[wintertriangles]

Before the noun, 이 means "this"

[carmelsweetie]

Oh, I didnt see the other answers here. But why not use 는 or 가?

[pajippio]

책상 ends in a consonant so you must use 이 to make 책상이. Words ending in a vowel can use 가 such as 사과 -> 사과가.
는/은 would be used to mark the topic and 이/가 is used for the subject.

Thank you, very helpful

[carmelsweetie]

Yeah, why is 이 being used twice?

[VAil682494]

The first 이 is to specify the object and the second 이 is a proposition that comes next to the noun

[Dei214213]

why is there no 것은 added after 이 when it's a proper sentence?

[nH544]

The way that my native Korean speaking friend explains it was that 것 replaces the noun, since we explicitly say desk, 이 is fine. As for no 은, the topic/subject marker comes after the desk as that is what we are talking about.

[habibaellamey]

Is 'desk' and 'book' have the same character in korean? '책' or am I confused? :o

[JunuKim1]

책 is book, 책상 is table...

[espitola]

what's the diff. between "... 기가 큽니다" and one w/o 기가?
