Korean is written using Hangul and a limited number of Han Ideographs. Hangul is an alphabetic/syllabic script made up of components called “jamos”. These jamo conjoin into syllable blocks. Han Ideographs are called Hanja in Korea. A limited set of Hanja is used for Korean with most words being written with Hangul. Some Hanja are visually different in North & South Korea than they are in other countries.
