I'm a karate instructor looking to supplement my instruction on skills and techniques with knowledge about the history, culture, and language. For instance, I found this snippet from Wikipedia intriguing:
[In the 1920s] the name was changed from 唐手 ("Chinese hand" or "Tang hand") to 空手 ("empty hand") – both of which are pronounced karate in Japanese
But I feel the factoid by itself is too sparse to pass along without the historical context of the relationship between Okinawa, China, and Japan (about which I know nil). What is the appropriate location/tag to post such questions on the history, language, and culture around - but not the practice of - karate?
