spelled oe into u (however, the spelling influenced other aspects in orthography, for example writing reduplicated words). All of the other changes were a part of the Perfected Spelling System, an officially mandated spelling reform in 1972. Some of the old spellings (which were derived from Dutch orthography) do survive in proper names; for example, the name of a former president of Indonesia is still sometimes written Soeharto, and the central Java city of Yogyakarta is sometimes written Jogjakarta. In time, the spelling system is further updated and the latest update of Indonesian spelling system issued on 16 August 2022 by Head of Language Development and Fostering Agency decree No 0424/I/BS.00.01/2022. Letter names and pronunciations The Indonesian alphabet is exactly the same as in ISO basic Latin alphabet. Indonesian follows the letter names of the Dutch alphabet. Indonesian alphabet has a phonemic orthography; words are spelled the way they are pronounced, with few exceptions. The letters Q, V and X are rarely encountered, being chiefly used for writing loanwords. In addition, there are digraphs that are not considered separate letters of the alphabet: Vocabulary As a modern variety of Malay, Indonesian has been influenced by other languages, including Dutch, English, Greek (from where the name of the country, Indonesia, is coming), Arabic, Chinese, Portuguese, Sanskrit, Tamil, Hindi, and Persian. It is estimated that there are some 750 Sanskrit loanwords in modern Indonesian, 1,000 Arabic loans, some of Persian and Hebrew origin, some 125 words of Portuguese, some of Spanish and Italian origin, and 10,000 loanwords from Dutch. The vast majority of Indonesian words, however, come from the root lexical stock of Austronesian (including Old Malay). The study of Indonesian etymology and loan words reveals both its historical and social contexts. Examples are the early Sanskrit borrowings from the 7th century during the trading era, the borrowings from Arabic and Persian during the time of the establishment of Islam in particular, and those from Dutch during the colonial period. Linguistic history and cultural history are clearly linked.
