Native numbers: 하나, 둘, 셋

These are the numbers Korean had before it borrowed the Chinese ones, and they go up to ninety-nine; above that the other set takes over. They count objects, people, animals, hours on the clock and years of age. Before a counter, five of them take a shorter form — 하나 becomes 한, 둘 두, 셋 세, 넷 네 and 스물 스무 — so it is 한 개, never 하나 개.
