Ewokese

Ewokese was the lively language spoken by the furry, diminutive Ewoks who lived on the forest moon of Endor. It was mutually intelligible with the language of the Yuzzum, and contained more than three dozen words for conifers that they inhabited. The most common of those terms was "life trees."

When the Rebel Alliance's strike team came to Endor to destroy the second Death Star's shield generator, the protocol droid C-3PO communicated with the Ewoks using Yuzzum, and managed to translate the Ewokese into Galactic Basic Standard so the Ewok named Wicket was able to guide the Rebels to the Imperial bunker.

Ewokese had a word to describe those who were not Ewoks, which literally translated to "nakeds" in Galactic Basic Standard.

The human scavenger Rey learned the language from a salvaged ship computer on Jakku, but had not found an opportunity to use it.
