Chinese or the Sinitic language(s) is a language family consisting of languages mutually unintelligible to varying degrees. Originally the indigenous languages spoken by the Han Chinese in China, it forms one of the two branches of Sino-Tibetan family of languages. About one-fifth of the world’s population, or over one billion people, speak some form of Chinese as their native language. The identification of the varieties of Chinese as "dialects" instead of "languages" is considered inappropriate by linguists and Sinologists.
