# Nguồn language

Nguồn (also Năm Nguyên) is a Vietic language spoken by the Nguồn people in the Trường Sơn mountains in Vietnam's North Central Coast region as well as in nearby regions of Laos.
Most Nguồn speakers in Vietnam live in the secluded Minh Hóa district of Quảng Bình Province, with others in the area around Đồng Lê, the seat of Tuyên Hoá District, approximately 50 km (31 mi) from the National Highway 1.
The Nguồn language has been variously described as a dialect of Vietnamese or as the southernmost dialect of Mường. Some researchers who consider it more closely related to Mường find that those who connect it more closely with Vietnamese are more influenced by ethnographic and/or political concerns than linguistic evidence. Chamberlain (2003) and Sidwell (2009) count it as a third Viet–Muong language.

## Geographic location

Most Nguồn live in Tuyên Hóa District (alongside the neighboring Sách people, a subgroup of the Chứt people who also speak a Vietic language) and in Minh Hoá District (living with the neighboring Việt peoples).
There are also Nguồn living in Laos, but with conflicting reports as to their exact location. According to Chamberlain (1998), there is a Nguồn village in central Laos known as Ban Pak Phanang in Boualapha District, Khammouane Province.

## Genealogical relations

Chéon (1907), Maspéro (1912), and Cuisinier (1948) considered Nguồn to be more closely related to Mường while Mạc (1964), Nguyễn Đ. B. (1975), and Phạm (1975) connected it with Vietnamese.
Later linguistic comparison by Nguyễn V. T. (1975) and Nguyễn Ph. Ph. (1996) suggest a closer link with the Mường dialects, and this is echoed by Barker (1993) (and others).
Jerold A. Edmondson, Kenneth J. Gregerson, and Nguyen Van Loi mention that this language is of "great interest to those studying the history of Vietic languages" due to its distinct historical developments.
Nguyễn V. T. (1975) notes that Nguồn speakers can communicate with Mường speakers with each speaking their own language, but Vietnamese speakers who do not know Mường cannot understand Nguồn.
Although closer to Mường generally (especially concerning sound system similarities), in some aspects Nguồn is more similar to Vietnamese. For example, the negative marker in Vietnamese is the particle không, which is ultimately a loanword from Chinese that became grammaticalized. The native negative marker chẳng, which is attested in earlier stages of Vietnamese, was largely replaced by the Chinese borrowing. Mường, in contrast, has preserved the original chẳng. Nguồn has, like Vietnamese, lost chẳng to không. In this feature of the loss of the native negative marker, Nguồn is like Vietnamese rather than Mường.

## Language variation

Nguyễn Ph. Ph. (1996) notes that there are two varieties of Nguồn:
* Cổ Liêm
* Yên Thọ (or An Thọ)
Cổ Liêm is named after the village of the same name; Yên Thọ is the name of a cooperative in Tân Hoá village.
The Yên Thọ variety is closer to Vietnamese than Cổ Liêm with respect to certain phonological developments.

## History

In 1905, Cadière reported that the Nguồn (as well as the Sách people) were to be found in valleys of the Nguồn Năn river in eleven villages. Originally there were two groups of five villages. The northern group was in Cơ Sa canton (along with some Việt villages) and consisted of the following villages:
* Qui Đạt
* An Đức
* Ba Nương
* Thanh Long
* Tân Kiều
Tân Kiều was later split into two villages resulting in a sixth village in the northern group:
* Tân Hợp
The more southerly village group consisted of
* Kổ Liêm
* Bốk Thọ
* Kim Bãng
* Tân Lí
* An Lạk
Mạc (1964) and Nguyễn Đ. B. (1975) assert that Nguồn is an original Việt group from the area of the Hà Tĩnh and Nghệ An provinces who moved into their present territory by the 17th century. Evidence for this opinion is based on family records. Mạc (1964) also reports that most Nguồn declared themselves to be Việt on the 1960 census.
Nguyễn V. T. (1975) suggests that the Mường could have migrated further south than Nghệ An to as far as Quảng Bình. Although some Việt families may have migrated to this region, they may have done so after Mường groups had already been established in the area. These Việt migrants could, then, have assimilated in language to the Mường. This Mường variety also would have been in contact with Chứt languages, like Sách. Thus, Nguyễn V. T. (1975) suggests that Nguồn is a variety of Mường spoken by Mường (possibly Hà Tĩnh Mường) and assimilated Việt people with influences from Chứt languages.
