The languages of Taiwan consist of several varieties of languages under the families of Austronesian languages and Sino-Tibetan languages. The Formosan languages, a branch of Austronesian languages, have been spoken by the Taiwanese indigenous peoples for thousands of years. Owing to the wide internal variety of the Formosan languages, research on historical linguistics recognizes Taiwan as the Urheimat (homeland) of the whole Austronesian languages family. In the last 400 years, several waves of Han emigrations brought several different Sinitic languages into Taiwan. These languages include Taiwanese Hokkien, Hakka, and Mandarin, which have become the major languages spoken in present-day Taiwan. Formosan languages were the dominant language of prehistorical Taiwan. Taiwan's long colonial and immigration history brought in several languages such as Dutch, Spanish, Hokkien, Hakka, Japanese, and Mandarin. Due to its colonial history, Japanese influences the language in Taiwan, for example, as many loanwords in several languages in Taiwan are derived from Japanese. After World War II, a long martial law era was held in Taiwan. Policies of the government in this era suppressed languages other than Mandarin in public use. This has significantly damaged the evolution of local languages, including Taiwanese Hokkien, Hakka, Formosan languages, and the Matsu dialect. The situation had slightly changed since the 2000s when the government made efforts to protect and revitalize local languages. Local languages became part of elementary school education in Taiwan, laws and regulations regarding local language protection were established for Hakka and Formosan languages, and public TV and radio stations exclusively for these two languages were also established. Currently, the government of Taiwan also maintains standards of several widely spoken languages listed below, the percentage of users are from the 2010 population and household census in Taiwan. Overview of national languages Indigenous languages The Taiwanese indigenous languages or Formosan languages are the languages of the aboriginal tribes of Taiwan. Taiwanese aborigines currently comprise about 2.3% of the island's population. However, far fewer can still speak their ancestral language, after centuries of language shift. It is common for young and middle-aged Hakka and aboriginal people to speak Mandarin and Hokkien better than, or to the exclusion of, their ethnic languages. Of the approximately 26 languages of the Taiwanese aborigines, at least ten are extinct, another five are moribund, and several others are to some degree endangered. The government recognizes 16 languages and 42 accents of the indigenous languages. The governmental agency Council
