The official languages of Singapore are English, Mandarin Chinese, Malay and Tamil, with the lingua franca between Singaporeans being English, the de facto main language in daily, governmental, legal, trade and commercial affairs. Among themselves, Singaporeans often speak Singlish, an English creole arising from centuries of contact between Singapore's multi-ethnic and multilingual society and its legacy of being a British colony. Linguists formally define it as Singapore Colloquial English. A multitude of other languages are also used in Singapore. They consist of several varieties of languages under the families of the Austronesian, Dravidian, Indo-European and Sino-Tibetan languages. The Constitution of Singapore states that the national language of Singapore is Malay. This plays a symbolic role, as Malays are constitutionally recognised as the indigenous peoples of Singapore, and it is the government's duty to protect their language and heritage. This is also largely due to Singapore's geographical location in the Malay Archipelago.
The three languages other than English were chosen to correspond with the major ethnic groups present in Singapore at the time: Mandarin Chinese had gained pre-eminent status (over the Southern Chinese dialects of the overseas Chinese) since the introduction of Chinese-medium schools; Malay was deemed the "most obvious choice" for the Malay community; and Tamil for the largest Indian ethnic group in Singapore, in addition to being "the language with the longest history of education in Malaysia and Singapore". In 2009, more than 20 languages were identified as being spoken in Singapore, reflecting a rich linguistic diversity in the city. Singapore's historical roots as a trading settlement gave rise to an influx of foreign traders, and their languages were slowly embedded in Singapore's modern day linguistic repertoire.
