Anh Cả (Brother Hai)
Once, while I was visiting South Vietnam, I had the opportunity to listen to the bus guide tell us about it. According to him, during our people’s march to the South, the eldest son must stay with his mother to support the family while his father, who is in the army, goes to the South alone. Far from his family and his homeland, he usually takes a second wife and has another child. This child will be called « sister Hai » or « brother Hai » because this corresponds to the rank « TWO » in the family consisting of several children. There is another hypothesis as follows:
During the Nguyen Dynasty, there was a tradition of refraining from any action that referred to the first name of the king or his relatives. This is why the word ĐẢM was replaced by the word ĐỞM because ĐẢM was the first name of Nguyễn Phúc Đảm (King Minh Mang) (can đảm meaning courage was transformed into can đỏm). King Minh Mang had a wife named Hồ Thị Hoa, mother of King Thiệu Trị. Viceroy Le Van Duyet built a bridge near a beautiful garden in Bến Nghé (the first district of today’s Ho Chi Minh City). It was originally called « flower bridge » (cầu HOA), which later became « cầu BÔNG. » It is said that the word « Cả » is not used because it refers to the eldest son of King Gia Long (Prince Cảnh). This is absurd because « Hương Cả » is the title given to the first person in the village in South Vietnam, often heard by the population and still used in the French colonial era. This is absurd because no one ever pays attention to the rank or title given.
It should be remembered that the Vietnamese are part of the Austro-Asiatic group. In addition to the Vietnamese, there are many other ethnic groups that are now called ethnic minorities such as the Tai-Kadai, the Austronesians, the Mường, the Hmong, the Cham etc.). Consequently, there is always the reciprocal borrowing of words in the vocabulary used by these ethnic groups. In South Vietnam, formerly it was the territory of the kingdom of Funan whose inhabitants were not the Khmer but the Austronesians like the Cham and the Mạ in the Đồng Nai region despite the annexation of this kingdom later by Chenla which later became the Angkorian empire of the Khmer. As their territory was too vast, the Khmer were unable to assume their presence everywhere. This is why the Funanese only became Khmer in places where contact was possible thanks to the assimilation policy. On the other hand, in other places the Funanese continued to live as before.
Being given the undeniable proximity of the Austro-Asiatic and Austronesian groups, proven for thousands of years by documents from genetic research work as recently as twenty years ago, the borrowing of the word HAK from the Funanese belonging to the Austronesian group in South Vietnam by the Vietnamese is very normal to designate children.
According to Vietnamese writer Bình Nguyên Lộc, the eldest son is always called « Son Hak » by the Funanese. So « sister Hai » or « brother Hai » used by the Vietnamese in South Vietnam obviously come from the Funanese. This is why in South Vietnam when you meet a Vietnamese with wavy hair, you can deduce that he is of Funanese origin like the Mạ in the Dong Nai region. A pure Vietnamese never has wavy hair but on the other hand has straight hair because he is part of the Southern Mongoloid group.
