 The name was later possibly adopted by the Melayu Kingdom, as it is common for people in the region to be known by the name of the river on which they settled.Another theory hold that it originates from the Tamil words "Malai" and "ur" meaning "mountain" and "city, land", respectively.An early literary appearance was in Vayu Purana where the word "Malaya Dvipa" (literally "mountainous dvipa") was mentioned, referring to the mountainous terrain of Malay Peninsula.
