Taekwondo is a Korean martial art and the national sport of South Korea. In Korean, tae means "to strike or break with foot"; kwon means "to strike or break with fist"; and do means "way," "method," or "art." Thus, taekwondo may be loosely translated as "the art of the foot and fist" or "the art of kicking and punching."

​

As many other arts, it combines combat techniques, self-defense, sport, exercise, and in some cases meditation and philosophy. In 1989, Taekwondo was claimed as the world's most popular martial art in terms of number of practitioners. Gyeorugi , a type of sparring, has been an Olympic event since 2000.

​

"Traditional taekwondo" typically refers to the martial art as it was established in the 1950s and 1960s in the South Korean military in particular, the names and symbolism of the traditional patterns often refer to elements of Korean history.

​

"Sport taekwondo" has evolved in the decades since then and has a somewhat different focus, especially in terms of its emphasis on speed and competition (as in Olympic sparring). Sport taekwondo is in turn subdivided into two main styles; One derives from Kukkiwon, the source of the sparring system sihap gyeorugi which is now an event at the summer Olympic Games and which is governed by the World Taekwondo Federation (WTF).
