Singapore Singapore has four official languages: English (Singapore English variety), Chinese (Singaporean Mandarin variety), Malay and Tamil. Although English is the primary language of business, government, and education, Malay is designated as the national language. This is due the recognition of ethnic Malays (approximately 14% of the population) as the indigenous peoples of Singapore. Traditionally, the lingua franca among the different ethnic groups in Singapore was Bazaar Malay, a Malay-based creole. Since independence, the government has been promoting English as the main language of Singapore. The bilingual education policy requires students to study two languages: English and a "mother tongue" corresponding to the student's ethnicity. Malay is only offered to non-Malay students as an optional third language in secondary schools. As a result, English has displaced Bazaar Malay as the common language among Singaporeans. Therefore, despite the status of Malay as the national language, the majority doesn't speak it as a first language. Slovakia The Slovak language is the national language of Slovakia.
