It's a very common and versatile word used in various contexts, such as:
* "Uri gajok" (우리 가족) - Our family
* "Uri chingu" (우리 친구) - Our friend
* "Uri nara" (우리 나라) - Our country
* "Uri eodi gane?" (우리 어디 가네?) - Where are we going?
It can also be used as a more informal and endearing way to address a group of people, similar to "guys" or "folks" in English.
