What is meaning of sith?

Sith is a term used in the Star Wars franchise to describe a group of evil and malevolent force-wielding beings who are often antagonists to the Jedi or force-sensitive beings. The term was first introduced as a concept in the Star Wars Legends continuity and was later adopted by the current canon. The Sith were founded by a Dark Jedi named Darth Bane who restructured the order and infused it with the power of the dark side of the force. The Sith are known for their use of the red-hued lightsabers, their tendency to operate in secrecy, and their lust for power and control. The term "Sith" has since become synonymous with evil, corruption, and betrayal.
