The purpose of this study was to trace a word(Taek-kyon) to its origin. Teak-Kyon is being called Tak-Kyon · Tae-Kyon · D?k-Kyon and so on. So That makes us confused a lot Which is the origin. It has 4 prerequisite what had been debated by scholar, I describe the prerequisite as follows. ① It. existed in Seoul and around Kyung-ki(京畿) Province only. ② It`s original pronunciation similar at Tak-Kyon. ③ It means a weapon-free martial art. ④ It derived from Chinese character. I admitted these prerequisite. so I searched for Chos?n(朝鮮) period`s document and founded some words written in Chinese characters which means a weapon-free martial art. For example, Kwon-bup(拳法) · Su-bak(手搏) · Byun(卞)· Baek-ta(白打) · Kwon-to(拳鬪) · Ta-Kwon(打拳) etc. Ta-kwon`s pronunciation is similar with Tak-kyon`s among examples. and It used only 1 or 2 years officially, After government used Kwan-bup(拳法) as official term but Ta-Kwon used among an illiterate people in Seoul. They maybe mentioned Ta-Kwon without Chines character. As it result, they forget the original pronunciation and the word. Finally, Taek-kyon`s pronunciation originated from Ta-kwon(打拳).
