West Sulawesi in the context of "Central Sulawesi"

East Kalimantan (Indonesian: Kalimantan Timur) is a province of Indonesia. Its territory comprises the eastern portion of Borneo/Kalimantan. It had a population of about 3.03 million at the 2010 census (within the present boundary), and 3.766 million at the 2020 census; the official estimate as at mid 2024 was 4,092,984. Its capital is the city of Samarinda, the most populous city on the entire island of Borneo.

East Kalimantan has a total area of 127,346.92 square kilometres (49,168.92 sq mi) and is the third least densely populated province in Kalimantan (after North Kalimantan and Central Kalimantan). The majority of the region shares a maritime border to the east with West Sulawesi and Central Sulawesi; its Cape Mangkalihat separates the Makassar Strait from the Celebes Sea. Its former northernmost region was split off on 25 October 2012 and is now the separate province of North Kalimantan; meanwhile it still shares land border to the west with West Kalimantan and Central Kalimantan; to its south, East Kalimantan borders South Kalimantan. The province bordered Sabah, Malaysia before the creation of North Kalimantan, and still has a short border with Sarawak, Malaysia through Mahakam Ulu Regency.

South Sulawesi (Indonesian: Sulawesi Selatan; Lontara: ᨔᨘᨒᨓᨙᨔᨗ ᨔᨛᨒᨈ) is a province in the southern peninsula of Sulawesi, Indonesia. The Selayar Islands archipelago to the south of Sulawesi is also part of the province. The capital and largest city is Makassar. The province is bordered by Central Sulawesi and West Sulawesi to the north, the Gulf of Bone and Southeast Sulawesi to the east, Makassar Strait to the west, and Flores Sea to the south.

The 2010 census estimated the population as 8,032,551, which makes South Sulawesi the most populous province on the island (46% of the population of Sulawesi is in South Sulawesi), and the sixth most populous province in Indonesia. At the 2020 Census, this had risen to 9,073,509, and the official estimate as of mid-2024 was 9,463,390 (comprising 4,701,970 males and 4,761,410 females). The main ethnic groups in South Sulawesi are the Buginese, Makassarese and Torajan. The economy of the province is based on agriculture, fishing, and the mining of gold, magnesium, iron, and other metals. The pinisi, a traditional Indonesian two-masted sailing ship, is still used widely by the Buginese and Makassarese, mostly for inter-insular transportation, cargo, and fishing purposes within the Indonesian archipelago.

The Lontara script (ᨒᨚᨈᨑ), also known as the Bugis script, Bugis-Makassar script, or Urupu Sulapa’ Eppa’ "four-cornered letters", is one of Indonesia's traditional scripts developed in the South Sulawesi and West Sulawesi region. The script is primarily used to write the Buginese language, followed by Makassarese and Mandar. Closely related variants of Lontara are also used to write several languages outside of Sulawesi such as Bima, Ende, and Sumbawa. The script was actively used by several South Sulawesi societies for day-to-day and literary texts from at least mid-15th Century CE until the mid-20th Century CE, before its function was gradually supplanted by the Latin alphabet. Today the script is taught in South Sulawesi Province as part of the local curriculum, but with very limited usage in everyday life.

Lontara is an abugida with 23 basic letters. The script is a descendant of Brahmi through Kawi intermediaries. As of other Brahmic scripts, each letter represents a syllable with an inherent vowel /a/, which can be changed with diacritics. The direction of writing is left to right. Traditionally, the script is written without word breaks (scriptio continua) and with little to no punctuation. A typical Lontara text may contain many ambiguities as coda syllables, or consonants at the end of syllables, are normally not written and must be supplied by readers from context.
