Ewokese/Legends

Ewokese was the language spoken by the Ewoks.

It was a primitive language, so besides its isolation, C-3PO was able to understand it.

Ewokese had no written form.

Contrarily to some beliefs, Ewoks were able to learn and speak other languages, including Basic.

Behind the scenes
The lyrics of the Ewok celebration song heard in the epilogue of the original edition of Return of the Jedi is the source for most of the Ewok vocabulary listed above.

Initially, Lucas wanted an artificial language based on mathematics. The computer program they used for this constructed something that looked much like ancient Greek.

Some have noted that certain phrases uttered by the Ewoks resemble real languages sampled from Earth, such as Tagalog (the language of the Philippines) and Swedish ("Ngayon, puno daw 'ito!", said when C-3PO is being worshipped, means "Now, this is a leader!" in Tagalog.)  Other phrases appear to be modified English (two Ewoks worshipping C-3PO seem to say something similar to "That guy's wise" and "Like I'm short.")
