Taekwondo (태권도) is a Korean martial art and the national sport of South Korea. In Korean, tae (태) means "to strike or break with foot"; kwon (권) means "to strike or break with fist"; and do (도) means "way," "method," or "art." Thus, taekwondo can be loosely translated as "the way of the foot and fist" or "the way of kicking and punching."
Taekwondo is the world's most popular martial art in terms of the number of practitioners. Its popularity has resulted in the varied development of the martial art into several domains: as with many other arts, it combines combat techniques, self-defense, sport, exercise, meditation, and philosophy. Taekwondo is also used by the South Korean military as part of its training. Gyeorugi, a type of sparring, has been an Olympic event since 2000.
