I'll continue with what I was too lazy to type yesterday, as the material was in printed form.
Movements and Strikes
In all seven combat styles, ancient terms are used that Jedi use to describe tasks, ways to achieve a goal, and the results that can be obtained during a lightsaber duel.
Strikes
Cho mai
The term cho mai is used to describe cutting off an opponent's arm holding a weapon. This strike indicates that the Jedi inflicting it seeks to inflict minimal damage on the opponent; cho mai also demonstrates the Jedi's high skill.
Cho mak
Cutting off an opponent's limb, such as the leg of a humanoid.
Cho Sun
This term describes a movement that leads to cutting off the opponent's arm that is holding a weapon.
Sai cha
The term sai cha is used to describe the rare instance when a Jedi executes their opponent. This technique is intended for the most dangerous opponents - those whom the Jedi cannot allow to remain alive. Sai cha is what Anakin Skywalker did to Count Dooku in Episode III.
Sai tok
A technique condemned by the Jedi due to its Sith nature, it cuts the opponent in two, separating the legs from the torso at the waist. Obi-Wan Kenobi, as a Padawan, did this to Darth Maul in "The Phantom Menace."
Shiak
Shiak is an act of mercy, stabbing a mortally wounded enemy.
Shiim
Inflicting a small scratch on the opponent with the edge of a lightsaber blade. It is also considered a sign of desperation or helplessness in a fight against a more powerful enemy.
Sun djem
Sun djem is an attack that aims to knock the weapon out of the opponent's hand. It is performed when one does not want to inflict physical harm on the opponent.
Movements
Jung
A 180-degree turn.
Jung ma
This term is used to describe a 360-degree turn maneuver, during which energy is accumulated for an attack on the enemy.
Kai-kan
Essentially, this is not a technique, but a staged performance of a famous, usually ancient, and very dangerous lightsaber duel, which can only be performed by well-trained Jedi.
Sai
A term used to describe a movement that Jedi perform when launching an attack on the legs. The Jedi jumps up, using the Force, and counterattacks from above, using the acceleration of free fall to increase the power of the strike.
Shun
This term is used when a Jedi makes a 360-degree turn, using their own arm as a lever and gaining additional speed for the attack.
