Statue of King Sejong (Gwanghwamun)
The statue of King Sejong was dedicated on 9 October 2009, in a ceremony attended by attended by President Lee Myung-bak and other Korean government official, on a Hangul Day in celebration of the 563rd anniversary of the invention of the Korean alphabet by King Sejong, two months after the Gwanghwamun Plaza opening. The golden statue is 6.2 meters high (another source gives the statue height as 9.5 meters and yet another, 6.7 meters) and weights 20 tons. The king has one hand raised and another placed on a book. Sides of the statue display all of the hangul alphabet characters. In front of the statue there are small models of a celestial globe, a rain gauge, and a sundial, the invention of which is also traditionally attributed to King Sejong in Korea. While King Sejong is best remembered for his invention of hangul, he is also considered to have been involved in promotion of agriculture, literature, science and technology, as well as Confucian philosophy, in Korea.
Origin of Hangul
Similarly, the coronal consonants (舌音 "tongue sounds") are said to show the (front of the) tongue bent up to touch the palate, the bilabial consonants (脣音 "lip sounds") represent the lips touching or parting, the sibilants (齒音 "incisor sounds") represent the teeth (in sibilants the airstream is directed against the teeth), and the guttural consonants (喉音 "throat sounds"), including the null initial used when a syllable begins with a vowel, represent an open mouth and throat. The labiodental consonants (輕脣音 "light lip sounds") are derived from the bilabial series. In all cases but the labials, the plain (清 "clear") stops have a vertical top stroke, the non-stops lack that stroke, and the aspirate stops have an additional stroke. There were a few additional irregular consonants, such as the coronal lateral/flap ㄹ , which the "Haerye" only explains as an altered outline of the tongue, and the velar nasal ㆁ . The irregularity of the labials has no explanation in the "Haerye," but may be a remnant of the graphic origin of the basic letter shapes in the imperial ’Phags-pa alphabet of Yuan Dynasty China.
