Tahitian
Although the official language of French Polynesia is French, the "unofficial" language, Tahitian, is spoken as much, if not more. There are about 125,000 people who speak Tahitian in French Polynesia and New Caledonia.
It is not uncommon to hear locals speaking a combination of Tahitian and French. Because of the way the Tahitian language is pronounced, it is generally easier for Americans to pronounce Tahitian words than it is for them to pronounce words in French. Unlike French (or even English), there are no confusing rules about how words are pronounced. In Tahitian, each letter has a certain sound and that sound remains the same, no matter what the combination of letters.
