Sign language

Sign language was a way of communicating that used gestures instead of voice to convey meaning.

Lacking vocal cords, the Anomids of Yablari communicated with one another through a sophisticated and very subtle combination of hand and body language. The Twi'lek people of Ryloth had developed a unique sign language using not their hands and arms, but their lekku, the fleshy appendages that hung from the back of their heads. Being natural speakers of Tusken but knowing they at times needed to open discussions with other peoples, Tusken Raiders were known to use a type of sign language known as Tusken Sign Language.

One type of sign language consisted in movements of or shapes made through the hands and arms. In one instance of its use in 21 BBY, Jedi Master Eeth Koth utilized sign language to provide the Jedi High Council with his hyperspace coordinates following his capture. Prisoners in the Narkina 5 Imperial Prison Complex, like Taga or Birnok, would use sign language to speach to each other through windows across the hallways.

The former bounty hunter Boba Fett partially used Tusken Sign Language sign language to communicate with his Tusken Raider tribe. A bounty hunter referred to as "The Mandalorian" utilized Tusken Sign Language to negotiate with two other Tusken Raiders.
