The only reason TKD instructors put "Karate" on the end of it is because of the meaning of the word Karate, as im sure you know it means "open hand defence" or basicly means unarmed combat. Which is what TaeKwon-Do is. So to say Karate is a martial arts is laughable, the martial arts is the actual style of 'karate' e.g shatokan etc. You could turn round and say that karate is Taekwon-Do, because they both mean pretty much the same thing. But Taekwon-Do did NOT originate from shatokan, from my research I understand that TKD is thought to have originated from Tae Kyon, which was the martial art practiced in Korea before the Japanese invaded. But the TKD we know today was influenced by japanese martial arts, as well the different Kwans that existed. With Honour & Respect... Nathan Rees, First Degree Black Belt
