- "Do you speak Bocce?"
"Of course I can, sir. It's like a second language to me…"
- ―Owen Lars and C-3PO
A language was 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 included Basic and Huttese. Less common examples included Aqualish, Bocce Lasat, Ithorese and Ubese and Ewokese. In order to overcome language barriers between beings from different species or ethnic groups, protocol droids were equipped with formidable language skills.
