Did GM Lee coin the characters?
Tang Soo = 唐手
Kara Te = 唐手
If GM Lee coined the term Tang Soo then he also must have coined Kara Te because they are exactly the same. Is that what you are claiming?
The two characters you post above are the same character, Tang.
And no he didn't coin the term tangsoo. No one said that he did. GM Lee coined the term tangsoo
do, which was not in use until he created it. As Nakayama Sensei explains, the term Tang or Tou was changed to Kong or Kara at the same time that the back end Jutsu or Sool was changed to Do, that this was the important change, not the tou to kara. So it went from Tang Soo Sool to Kong Soo Do. There was no Tang Soo Do until GM LEE Won Kuk used it. My documentation is Nakayama Sensei's words below.
Again, here is what NAKAYAMA Masatoshi Sensei stated in the book, Conversations with the Master: Masatoshi Nakayama, page 32:
"Well, the characters for karate had become rather well known by the 1930's, but they were still read "Chinese hand". In 1935, Master Funakoshi wrote Karate-do Kyohan and proposed that the characters be changed to "empty hand"....
But more importantly, he also proposed that karate-jutsu, the technique of karate, be changed to karate-do, karate as a way of life. This caused tremendous uproar among some of the older, more traditional Okinawan masters of the time, and they took a strong stand against him in the newspapers. They demanded to why he wanted to remove karate from its Okinawan and Chinese roots. His reply to them was very interesting. He said, in effect, that since karate had spread to the Japanese mainland and been accepted by the intelligentsia in Japan, it had ceased to be a local, Okinawan martial art. He said it had grown to universal proportions and acceptance, and should therefore be elevated to equal status with kendo, Japan's oldest martial art, and judo, which was very popular."
