The Korean alphabet, also known as Hangul is the native alphabet of the Korean language. It was created during the Joseon Dynasty in 1443, and is now the official script of both South Korea and North Korea. The Korean alphabet was invented in 1443 during the reign of the Great King Sejong. There are 14 basic consonants and 10 basic vowels. Letters that have similar sounds also have similar shapes, so it is easy to learn.
