General.
Most texts written about this subject was written by foreign travelers. As a result, information about this ancient kingdom is often disputed.
Etymology.
George Cœdès thinks that the word "Funan" came from the word "Bnaṃ" or "Vnaṃ" in old Khmer. The modern Khmer word "Phnom" (meaning mountain or hill) came from this word. Claude Jacques, however, disputes this theory. He pointed out that there is a wrong translation of the Sanskrit word "Parvatabùpála" as "Bnaṃ." There is no ancient Khmer text found using this word to refer to this kingdom.
There are other explanations on how the word was formed. Claude Jacques believes the Chinese created this name because they likes to add "" ("nan") to refer to regions "to the south" (Yunnan, Hainan, ...).
Capital.
The exact location of the capital is not known. The Book of Liang said the capital is 500 li (250 kilometers) from the sea, so it might be in Ba Phnom (Cambodian province of Prey Veng), Angkor Borei (in the Cambodian province of Takeo) or Óc Eo (now in Vietnam).
George Cœdès believes the name of the capital is "Vyadhapura" (city of hunters) because Angkorian texts described about it. The Book of Tang also recorded the word "Témú" (old Khmer "Dalmāk)" which also means "hunter". But Michael Vickery disputes this claim because of two reasons. First, the two words have different meaning. The "Vyadhapura" killed the animal, but the "Dalmāk" brought the animal home alive. Second, the word "Dalmāk" appeared for the first time in the ninth or early tenth century, and the word "Témú" appeared in Chinese texts for the first time in the sixth century (Funan: 1st—7th century).
