Kugyà Âl (also Romanized as gugyeol or kwukyel, among others) is a family of annotation systems for rendering texts written in Classical Chinese into understandable Korean. Believed to have been developed after the introduction of Chinese Characters during the Three Kingdoms period of Korea, its oldest record is found within Buddhist texts in Chinese from the Goryeo period; reached the height of its use during the Joseon dynasty, when readings of the Chinese classics were of paramount social importance.
In kugyà Âl, the original text in Classical Chinese was not modified, and the additional markers were simply inserted between words or phrases. Therefore, ignoring the kugyà Âl annotations, the text would be readable as regular Classical Chinese.
The term kugyà Âl (Hanja: ) can be rendered as "phrase parting" and may refer to the separation of one Chinese phrase from another. This name is itself believed to originate from the use of hanja characters to represent the Middle Korean phrase ipgyeot (), with a similar meaning. Kugyà Âl is also sometimes referred to as to (), or hyeonto (), since to is also used to refer to the morphological affixes themselves or as seogui (), which can be rendered as "interpretation of the classics."
Depending on the period, the kugyà Âl markings were (sometimes abbreviated) Chinese characters, called jato kugyà Âl (). In some cases, they were marked with simple dots and lines, called jeomto kugyà Âl () whose positions and angles relative to the Chinese character encoded its reading. Jeomto kugyà Âl is similar to the okototen system in Japanese. After the advent of Hangul in the 15th century, kugyà Âl also started to be written using Hangul, called hangul kugyà Âl ().
The kugyà Âl annotations were marked on paper using a stylus with no ink, called gakpil kugyà Âl (), or handwritten with ink, or in some cases printed with the Classical Chinese text.
Some early kugyà Âl specify the order in which the Chinese words should be read, effectively reordering the Chinese sentence into Korean word order. This is called yeokdok kugyà Âl () or seokdok kugyà Âl (), which is comparable to kanbun kundoku in Japanese. On the other hand, the vast majority of later instances of kugyà Âl keep the original Chinese word order. This is called sundok kugyà Âl ().
Kugyà Âl is first attested from the 11th century in the early Goryeo dynasty, but evidence indicates it likely dates back to the 7th century or earlier. It is theorized that the system was created after the introduction of Classical Chinese during the Three Kingdoms period, where each kingdom (Goguryeo, Paekche, and Silla) created branches within their governments to better study and popularize the Chinese Characters. Regardless, contemporary evidence indicates that certain hanja characters were used (along with specialized symbols) to represent Korean sounds through their meaning. For example, the syllable 'ìÂÂ' (is) was represented with the hanja character since that character has the Korean meaning 'ìÂÂë¤.' This technique came to be replaced in the late Goryeo period with using hanja characters according to their sound. The later version of the kugyà Âl system was formalized by Chà Âng Mong-ju and Kwà Ân Kà Ân around 1400 in the early Joseon Dynasty, at the behest of King Taejong. Many Confucian classics, including the Classic of Poetry, were rendered into kugyà Âl at the time.
The term kugyà Âl is often extended beyond this early system to similar uses of hangul following the introduction of the Hunminjeongeum in the 15th century. In this respect, kugyà Âl remains in occasional use in contemporary South Korea, where such techniques are still sometimes used to render the Confucian classics into readable form.
Kugyà Âl should be distinguished from the idu and hyangchal systems, which preceded it. Kugyà Âl used specialized markings, together with a subset of hanja, to represent Korean morphological markers as an aid for Korean readers to understand the grammar of Chinese texts. Also, the idu and the hyangchal systems appear to have been used primarily to render Korean into hanja; on the other hand, kugyà Âl sought to render Chinese texts into Korean with a minimum of distortion.
