Pluricentric in the context of "Ausbau language"

Malay (UK: /məˈleɪ/ mə-LAY, US: /ˈmeɪleɪ/ MAY-lay; endonym: Bahasa Melayu, Jawi script: بهاس ملايو) is an Austronesian language spoken primarily by Malays in several islands of Maritime Southeast Asia and the Malay Peninsula on mainland Asia. The language is an official language of Brunei, Malaysia, and Singapore. Indonesian, a standardized variety of Malay, is the official language of Indonesia and one of the working languages of Timor-Leste. Malay is also spoken as a regional language of ethnic Malays in Indonesia, southeast Philippines and the southern part of Thailand. Altogether, it is spoken by 60 million people across Maritime Southeast Asia.

The language is pluricentric and a macrolanguage, i.e., a group of mutually intelligible speech varieties, or dialect continuum, that have no traditional name in common, and which may be considered distinct languages by their speakers. Several varieties of it are standardized as the national language (bahasa kebangsaan or bahasa nasional) of several nation states with various official names: in Malaysia, it is designated as either Bahasa Melayu ("Malay language") or in some instances, Bahasa Malaysia ("Malaysian language"); in Singapore and Brunei, it is called Bahasa Melayu ("Malay language") where it in the latter country refers to a formal standard variety set apart from its own vernacular dialect; in Indonesia, an autonomous normative variety called Bahasa Indonesia ("Indonesian language") is designated the bahasa persatuan/pemersatu ("unifying language" or lingua franca) whereas the term "Malay" (bahasa Melayu) refers to vernacular varieties of Malay indigenous to areas of Central to Southern Sumatra and West Kalimantan as the ethnic languages of Malay in Indonesia.
