Language (Earth-2356)

A language is a method of sentient communication, either oral or written, consisting of the use of sounds and words in a structured and conventional way.

Prevalent languages in the galaxy include Galactic Basic, and Bocce. Languages like Huttese, Aqualishi, Sangheilian and Mando'a dominated in systems controlled by those societies.

Some languages use more than one script. For instance, Galactic Basic use the Aurebesh, Outer Rim Basic, and High Galactic forms of written communication depending on the situation. Additionally, most societies use a base ten number system, however, there are exceptions. Jawas used a base nine system, and the Hutts count on their fingers, of which they only have eight, and their numbers jump from seven to ten.

In order to overcome language barriers between beings from different species or ethnic groups, protocol droids are equipped with formidable language skills. When communicating among several species, a trade language such as Sy Bisti or Jawa Trade Talk can be used.

To some, music is considered an universal language.
