Native Korean Numbers

   Native Korean Numbers are used to express time and units. They are generally used along with unit nouns that express the appropriate unit when counting things or people. Example of unit nouns include 명,마리,개,살,병, and 잔. In this cases, Korean numbers that precede these nouns are written in slightly different forms: 하나 becomes  한 (학생 한 명), 둘 becomes 두 (새 두 미리),셋 becomes세 (커피 세 잔), 넷 becomes 네(콜라 네 병), 스물 becomes 스무 (사과 스무 개).
