Twi'leki

Twi'leki, also known as Ryl, was a language spoken by Twi'leks from Ryloth. It combined verbal sounds and an elaborate sign language using the Twi'lek's head-tails, called lekku. That sign language allowed the Twi'leks to communicate complete concepts without having to pronounce a single word. Raising the tip of one's right lek meant "Hello!" while dipping the tip of one's left lek meant "Goodbye!" By crossing over both lekku tips twice, a Twi'lek meant to say "I love you." Both lekku tips jabbed into the speaker's back were to be understood as "May spice salt your wounds!"

The Twi'lek Jedi Knight Aayla Secura knew how to speak both Twi'leki and Galactic Basic Standard. Upon being shown the body of the deceased Jedi Master Fondar Etzis, she bid goodbye to him in Twi'leki. Jedi Master Obi-Wan Kenobi was able to speak Ryl; however, being human, he was only able to communicate verbally.
