Gungan Basic, also called Gunganese, was the language spoken by the Gungans of the planet Naboo. It was a language mostly derived from Naboo settlers' language, Basic, spoken in an accent. Occasionally, a word from Old Gungan would appear in dialogue, a term usually without any obvious meaning unless translated.
Humans could usually understand it and, similarly, Gungans could understand Humans speaking Basic (even in written form). Most one-syllable words pertaining to the self would contain a suffix of -sa, for example, "We-sa" and "You-sa". Many one-syllable words ending in a consonant would end with -u.
I am - Mesa (if followed by an adjective) or *My (if followed by another verb)
You are - Yousa
He is - Hesa
She is - Shesa
It is - Isa (pronounced "izzuh")
We are - Wesa
You (plural) are - Yousas
They are - Deysa
* You would use "my" if there was a verb after the "I am", such as "I am jumping" or "I am going". For "I am going", you wouldn't say "Mesa going". But you would say "My goen" because of this rule. (Also, the suffix -ing is replaced by -en. It's "goen", not "going".)
The Gungan variant of Basic was first heard in the 1999 movie Star Wars Episode I: The Phantom Menace, the first installment of the prequel trilogy.[3] After the release of The Phantom Menace, writer Ryder Windham created a Gungan glossary for internal use at Lucasfilm. This document provided English-to-Gungan translations of several common phrases and the numbering system, and also set down the rules for sentence construction.[4]
