All Jedi Forms involve the same ‘marks of contact’, target objectives organized as categories of damage lightsabre-wielders can inflict upon their opponents. In the names of these marks, the language of the earliest Jedi sages has come down unaltered to us today. The ancient traditional marks of contact help focus a Jedi’s attacks and defenses on a few clear categories rather than diffusing awareness across an infinite number of possibilities.


Damage Or Destroy A Weapon
Sun djem (“sun jem”)
Sun djem (disarming) was a goal of early Form I masters, since destroying an opponent’s lightsabre could win victory without causing injury – always a Jedi aspiration. However, the advances of Form II made sun djem nearly impossible, since combatants trained studiously against having their weapons taken or damaged.

Wound
Shiim (“She-eem”)
Any kind of wound with the edge of a lightsabre blade is shiim. An inconclusive mark of contact, shiim is considered inferior to other marks that decisively end a battle. Its appearance thus expresses struggle with a powerful opponent.

Stab
Shiak (“She-ack”)
Jedi tradition considers shiak (stabbing) an honorable method of inflicting serious injury since it causes the least visible injury to the opponents. Shiak can thus express Jedi respect for an opponent and the living Force even as it delivers a fatal blow.

Cut Off Weapon Hand
Cho mai (“cho my”)
Cho mai instantly ends an opponent’s ability to use a weapon but does not kill, making cho mai a preffered Jedi move. The precision of cutting off only a hand is considered mark of a superior lightsabre master.

Cut Off Weapon Arm
Cho sun (“cho sun”)
Cho sun (dismembering), cutting off an opponent’s entire weapon arm, is a move lacking the precision and elegance of cho mai, but cho sun is the move most often necessary under surprise combat conditions or where no chances can be taken.

Otherwise Maim
Cho mok (“cho mock”)
Cho mok (maim) describes the cutting off of an opponet’s leg or (in the case of non-humans) other limb or appendage such as lekku (head-tails).

Behead
Sai cha (“sigh cha”)
Sai cha, from the ancient words for “separate” and “head”, describes the chilling Jedi ability to behead an opponent in a flash of the lightsabre. Jedi commit sai cha only when battle is at it’s most deadly serious and threatening, or when an opponent is considered extremely dangerous even to a fully trained Jedi.

Cut Body In Half
Sai tok (“sai tock”)
Jedi consider the bisection of a living opponent’s body a form of butchery, a desecration to be avoided if possible. The savage extreme of sai tok is thus normally used only against battle druids. Sai tok represents a potentially Sith-like desire to destroy one’s enemy, whereas the Jedi goal even in combat is inner focus on defeating the danger of opponents rather than hating them and wishing utter destruction upon them.
