History of the Malay language
Malay was first used in the first millennia known as Old Malay, a part of the Austronesian language family. Over a period of two millennia, Malay has undergone various stages of development that derived from different layers of foreign influences through international trade, religious expansion, colonisation and developments of new socio-political trends.
