Jujutsu (/dʒuːˈdʒuːtsuː/ joo-JOOT-soo; Japanese: 柔術, jūjutsu   listen (help·info)), westernized[citation needed] as jiu-jitsu, is a Japanese martial artand a method of close combat for defeating an armed and armored opponent in which one uses no weapon or only a short weapon.[1][2] "Jū" can be translated to mean "gentle, soft, supple, flexible, pliable, or yielding." "Jutsu" can be translated to mean "art" or "technique" and represents manipulating the opponent's force against himself rather than confronting it with one's own force.[1] Jujutsu developed to combat the samurai of feudal Japan as a method for defeating an armed and armored opponent in which one uses no weapon, or only a short weapon.[3]Because striking against an armored opponent proved ineffective, practitioners learned that the most efficient methods for neutralizing an enemy took the form of pins, joint locks, and throws. These techniques were developed around the principle of using an attacker's energy against him, rather than directly opposing it.[4] 

There are many variations of the art, which leads to a diversity of approaches. Jujutsu schools (ryū) may utilize all forms of grappling techniques to some degree (i.e. throwing, trapping, joint locks, holds, gouging, biting, disengagements, striking, and kicking). In addition to jujutsu, many schools teach the use of weapons. Today, jujutsu is practiced in both traditional and modern sports forms. Derived sport forms include the Olympic sportand martial art of judo, which was developed by Kanō Jigorō in the late 19th century from several traditional styles of jujutsu, and Brazilian jiu-jitsu, which was derived from earlier (pre–World War II) versions of Kodokan judo.

A leglock is a joint lock that is directed at joints of the leg such as the ankle, knee or hip joint. A leglock, which is directed at joints in the foot, is sometimes referred to as a foot lock and a lock at the hip as a hip lock.  Leglocks are featured, with various levels of restrictions, in combat sports and martial arts such as Sambo, Brazilian Jiu Jitsu,  catch wrestling, mixed martial arts, Shootwrestling and submission wrestling, but are banned in some sports featuring joint locks such as judo.
