Cham language in the context of Cham Jawi

The Arabic script is the writing system used for Arabic (Arabic alphabet) and several other languages of Asia and Africa. It is the second-most widely used alphabetic writing system in the world (after the Latin script), the second-most widely used writing system in the world by number of countries using it, and the third-most by number of users (after the Latin and Chinese scripts).

The script was first used to write texts in Arabic, most notably the Quran, the holy book of Islam. With the religion's spread, it came to be used as the primary script for many language families, leading to the addition of new letters and other symbols. Such languages still using it are Arabic, Persian (Farsi and Dari), Urdu, Uyghur, Kurdish, Pashto, Punjabi (Shahmukhi), Sindhi, Azerbaijani (Torki in Iran), Malay (Jawi), Javanese, Sundanese, Madurese and Indonesian (Pegon), Balti, Balochi, Luri, Kashmiri, Cham (Akhar Srak), Rohingya, Somali, Mandinka, and Mooré, among others. Until the 16th century, it was also used for some Spanish texts, and—prior to the script reform in 1928—it was the writing system of Turkish.

Champa (Cham: ꨌꩌꨛꨩ, چمڤا; Khmer: ចាម្ប៉ា; Vietnamese: Chiêm Thành 占城 or Chiêm Bà 占婆; modern Vietnamese Chăm Pa) was a collection of independent Cham polities that extended across the coast of what is present-day central and southern Vietnam from approximately the 2nd century AD until 1832.

According to earliest historical references found in ancient sources, the first Cham polities were established around the 2nd to 3rd centuries AD, in the wake of Khu Liên's rebellion against the rule of China's Eastern Han dynasty, and lasted until when the final remaining principality of Champa was annexed by Emperor Minh Mạng of the Vietnamese Nguyễn dynasty as part of the expansionist Nam tiến policy. The kingdom was known variously as Nagaracampa (Sanskrit: नगरचम्प), Champa (ꨌꩌꨛꨩ) in modern Cham, and Châmpa (ចាម្ប៉ា) in the Khmer inscriptions, Chiêm Thành in Vietnamese, Campa in Malay, Zhànchéng (Mandarin: 占城) in Chinese records, and al-Ṣanf (Arabic: صَنْف) in Middle Eastern Muslim records.

The Chams (Cham: ꨌꩌ, چام, cam), or Champa people (Cham: ꨂꨣꩃ ꨌꩌꨛꨩ, اوراڠ چمڤا, Urang Campa; Vietnamese: Người Chăm or Người Chàm; Khmer: ជនជាតិចាម, Chônchéatĕ Cham), are an Austronesian ethnic group in Southeast Asia and are the original inhabitants of central Vietnam and coastal Cambodia before the arrival of the Cambodians and Vietnamese, during the expansion of the Khmer Empire (802–1431) and the Vietnamese conquest of Champa (11th–19th century).

From the 2nd century, the Chams founded Champa, a collection of independent Hindu-Buddhist principalities in what is now central and southern Vietnam. By the 17th century, Champa became an Islamic sultanate. Today, the Cham people are largely Muslim, with a minority following Hinduism, both formed the indigenous Muslim and Hindu population in both Cambodia and Vietnam. Despite their adherence to Islam, the Cham people still retain their ancestral practice of matriarchy in family and inheritance.

The Chamic languages, also known as Aceh–Chamic and Acehnese–Chamic, are a group of ten languages spoken in Aceh (Sumatra, Indonesia) and in parts of Cambodia, Thailand, Vietnam and Hainan, China. The Chamic languages are a subgroup of Malayo-Polynesian languages in the Austronesian family. The ancestor of this subfamily, proto-Chamic, is associated with the Sa Huỳnh culture, its speakers arriving in what is now Vietnam from Formosa.

The most widely spoken Chamic languages are Acehnese with 3.5 million speakers, Cham with about 280,000, and Jarai with about 230,000, in both Cambodia and Vietnam. Tsat is the most northern and least spoken, with only 3000 speakers.

The Đông Yên Châu inscription is an Old Cham inscription written in Pallava script, found in 1936 at Đông Yên Châu, northwest of Trà Kiệu, which used to be the old Champa capital known as Simhapura, in central Vietnam. The inscription was written in prose, is the oldest document of Cham (and indeed of any Austronesian language), and testifies to the existence of indigenous beliefs among the ancient Cham people of the Champa kingdom. Though not itself dated, the phrasing of the inscription is identical to those of dated Sanskrit inscriptions of Bhadravarman I of the second dynasty, who ruled Champa at the end of the 4th century CE. It contains an imprecatory formula ordering respect for the "naga of the king", undoubtedly a reference to the protective divinity of a spring or well. This vernacular text shows that in the 4th century, the land that now constitutes modern-day central Vietnam was inhabited by an Austronesian-speaking population. The evidence, both monumental and palaeographic, also suggests that Hinduism was the predominant religious system.

The fact that the language in the inscription shares some basic grammar and vocabulary with Malay has led some scholars to argue that the inscription contains the oldest specimen of Malay words in the form of Old Malay, older by three centuries than the earliest Srivijayan inscriptions from southeastern Sumatra. However, most scholars consider it established that this inscription was written in Old Cham instead. The shared basic grammar and vocabulary comes as no surprise, since Chamic and Malayic languages are closely related; both are the two subgroups of a Malayic–Chamic group within the Malayo-Polynesian branch of the Austronesian family.

Sri Mara (Cham: ꨦꨴꨫ ꨠꨩꨣ, Khmer: ឝ្រី មារ, Thai: ศรีมาระ fl. 137 or 192 AD), also known as Khu Liên or Ou Lian (Chinese: 甌連), was the founder of the kingdom of Lâm Ấp in 192. He was originally a local official of Xianglin (Tượng Lâm), then under the rule of the Chinese Eastern Han dynasty.
