Edit: Both are adjectives. 있는 'that there is' or 'that have something or someone' 없는 'that there isn't' or 'that have no something or someone' 피자 없는 세상은 생각도 하기 싫어 I hate to think of the world that there's no pizza in. - I can't imagine the world there's no pizza in. 걔는 아침잠이 없는 애야. S/he is a kid that has no 'morning sleep'. - S/he is one who wakes up early. (even though s/he doesn't try to) 나 돈 필요한데 돈 좀 있는 사람? I need some money, anyone has some extra money? 동생 있는 사람은 동생 없는 사람보다 책임감이 더 강한 것 같아. One who has younger brother/sister seems to have more resposibility than other one who has no younger brother/sister. Correction: '있는' 이랑 '없는' 이 무슨 뜻이에요? '있는' 이랑 '없는' 어떻게 써요? 전 모르겠어요... 예를 들어서 설명해주세요. ᄏᄏ 제가 쓴 글도 좀 고쳐주세요 ^_^

~이/가 있는 => there is ~ ~이/가 없는 => there is no ~
