Hawai'i is also the only American state to have two official languages, Hawaiian and English. However, a 3rd unofficial language is also widely spoken, Pidgin which is a slang combining words from many aspects of island life and culture.
In 1978, this state made English and Hawaiian its official languages. More than a quarter (26.7%) of this state's residents speak a language other than English. The most common of these languages are Japanese, Tagalog (Philipino), Ilocano, and Chinese. This state has the nation's highest proportion of speakers of Chinese, Tagalog, Japanese, Korean, Samoan, and Ilocano.
