Taekwondo (태권도; 跆拳道; Korean pronunciation: [tʰɛkwʌndo])[a] is a Korean martial art and the national sport of South Korea. In Korean, tae (태, 跆) means "to strike or break with foot"; kwon (권, 拳) means "to strike or break with fist"; and do (도, 道) means "way," "method," or "art." Thus, taekwondo may be loosely translated as "the way of the foot and fist" or "the way of kicking and punching."
