Source-derived summary

Indonesian orthography refers to the official spelling system used in the Indonesian language. The current system uses the Latin script and is called Ejaan yang Disempurnakan (EYD), commonly translated as Enhanced Spelling, Perfected Spelling or Improved Spelling.

History

The Perfected Spelling system is a system of orthography released in 1972 to replace the existing Republican Spelling System (RSS, also called the Soewandi Spelling System, SSS). A joint initiative of Indonesia and neighbouring country Malaysia (which also introduced the similar Joint Rumi Spelling system), the aim of the change in 1972 was to introduce greater harmonisation of the Indonesian and Malay-language orthographies. The new EYD system, adopted on the 27th anniversary of Indonesia's independence on 17 August 1972, was decreed by President Suharto the previous day. Government departments were instructed to begin using the EYD system on 1 January 1973. On 27 August 1975, the Minister of Education and Culture issued a decree which provided a detailed explanation of the changes in the new system and marked the official use of the EYD system. It was formerly known as the Indonesian Spelling System (Ejaan Bahasa Indonesia, EBI), often referred to as the Indonesian Spelling System General Guidelines (Pedoman Umum Ejaan Bahasa Indonesia, PUEBI), between 2015 and 2022.

Editorial summary

This brief starts where responsible research should: with the source description of “Indonesian orthography” as spelling system currently used for the Indonesian language. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1972, 1973, 1975, 2015—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Indonesian, orthography and spelling can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as spelling system currently used for the Indonesian language. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q5378777. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1972, 1973, 1975 and 2015.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
