it is not referred to with the term "Malay" in common parlance. The term "Malay" is usually reserved for the forms of Malay indigenous to the Malay ethnic group (the national standardized language of Malaysia and the non-standard idioms of Malay people, including those used by Malay Indonesians). Thus, "Malay" is considered a regional language (bahasa daerah) in Indonesia, enjoying the same status as e.g. Javanese, Sundanese, Buginese, Balinese, Batak languages and others. Moreover, to some Indonesians, the term "Malay" is more often associated with Malaysia and the Malaysian variety of Malay. In Malaysia, the terms "Indonesian Malay" and "Malaysian Malay" are sometimes used for Indonesian and Malay as spoken in Malaysia. In Indonesia, "Indonesian Malay" usually refers to the vernacular varieties of Malay spoken by the Malay peoples of Indonesia, that is, to Malay as a regional language in Sumatra, though it is rarely used. Bahasa Malaysia and Bahasa Melayu are used interchangeably in reference to Malay in Malaysia. Malay was designated as a national language by the Singaporean government after independence from Britain in the 1960s to avoid friction with Singapore's Malay-speaking neighbours of Malaysia and Indonesia. It has a symbolic, rather than functional purpose. It is used in the national anthem "Majulah Singapura", in citations of Singaporean orders and decorations and in military commands. Singaporean Malay is officially written in the Latin-based Rumi script, though some Singaporean Malays also learn the Arabic-based Jawi script. Jawi is considered an ethnic script for use on Singaporean identity cards. Orthography Before the 20th century, Malay was written in a local modified form of the Arabic alphabet known as Jawi. During the 20th century, Malay written with Roman letters, known as Rumi, almost completely replaced Jawi in everyday life. The romanisations originally used in British Malaya (now part of Malaysia) and the Dutch East Indies (now Indonesia) reflected their history as British and Dutch colonial possessions respectively. In British Malaya, the romanisation of Malay, devised by Richard Wilkinson was influenced by English, whereas in the Dutch East Indies, the system devised by C. A. Van Ophuijsen was influenced by Dutch. As a result, in Indonesia, the vowel was formerly represented oe, as in Dutch, although the official spelling of this sound was changed to u in 1947 when the Republican Spelling System was used. Similarly, until 1972, was represented in Malaysia as ch, whereas in Indonesia, it continued to follow Dutch
