Rejang script

The Rejang script is of the Brahmic type, and is related to other scripts of the region, like Batak,Buginese, and Kerinci. Rejang was first written with a script known as Aksaro Riking ("lines by the knife") or Kaganga (from the first three letters).

The Rejang script is classified as belonging to a group of scripts known as Surat Ulu ("upstream scripts"), which includes the Bengkulu, Lembak, Lintang, Lebong, and Serawai scripts. It is widely believed to be evolved from Indic scripts used in Srivijaya Kingdom, a city-state based on Sumatra from 650-1377 AD.

The script was in use prior to the introduction of Islam to the Rejang area; the earliest attested document appears to date from the mid-18th century CE. The Rejang script is sometimes also known as the KaGaNga script following the first three letters of the alphabet.

According to folk tales, the Rejang script was first written with sharp tools including sickle which produces sharp lines. According to other tales, Rejang script is referred to as rikung due to its cornering angles. There are 19 main consonants (buak tu'ai) in Rejang script, changes in vowel sound (tando ketikeak) and 9 doubling consonants (buak ngimbang).

Vowel signs are used in a manner similar to that employed by other Brahmi-derived scripts. Consonants have an inherent /a/ vowel sound. Consonant conjuncts are not formed.

The Moken people

The Moken are an Austronesian ethnic group that occupies the west coast of Thailand on the Andaman Sea. They also occupy the Mergui Archipelago off Myanmar’s coast.

Austronesians include populations of migrants, nomads, farmers, and especially seafarers who colonized an area of several million square kilometres. They crossed great distances through cultural or geographic boundaries, the Sulu Empire, maritime powers, mainland empires, emerging nations, straits... that temporarily stopped their movements and allowed them to recompose their fragmented ethnicity.

The Moken language belongs to the Malayo-Polynesian branch of the Austronesian language family. The Moken live as hunters and gatherers of the resources found on the land and in the sea. Moken ethnohistory asserts their ancestral ties to mainland SEA. According to these accounts,

Moken ancestors lived in settlements of the Myanmar–Malaya mainland and practiced agriculture, but were driven to the coast by the Burmese to the north and the Malays to the south, and subsequently settled in the Mergui Archipelago. Continuous raiding by pirates further forced the Moken to adopt a sea-based lifestyle to avoid capture.
