The Korean language is classified as a Ural-Altaic language, a group which also includes Mongolian, Hungarian, and Finnish. The Korean character system, "hangul", is completely different from and independent of Chinese and Japanese. 'Hangul' was developed by a group of scholars under the patronage of King Sejong in 1443. It is composed of 10 vowels and 14 consonants, which are used to form numerous syllabic groupings.
In Korea, most names have three parts, one family name, and a first name with two parts. For example, with Kim Jung Wu. His family name is Kim (Mr Kim as we know it).
In Korea, the family comes first, then the first names – opposite to western names. In this example, the first name is Jung Wu – always spoken together.
Some Koreans also have a Christian name – often chosen from the bible. In this case this person also has an English first name of John. So his name could be referred to as: Mr Kim, John Kim, Kim Jung Wu.
