Quảng Lâm language

Quảng Lâm is an unclassified, poorly attested Austroasiatic language spoken in Quảng Lâm commune, Mường Nhé District, Điện Biên Province, northwestern Vietnam. Nguyễn Văn Huy (1975) is the only published resource contain data of Quang Lam. The Ethnologue lists Quang Lam as an alternate name for Kháng.

Quang Lam speakers are officially classified as ethnic Khang people. Tạ (2021) refers the language as Kháng Quảng Lâm.

Classification
Nguyen (1975) speculates that Quang Lam may be closely related to Kháng (variously classified as either a Palaungic or Khmuic language), but this has yet to be verified. Data is scanty and presented only in Vietnamese orthography (Quốc Ngữ). Quang Lam speakers claim to not have an autonym, and simply call themselves "Brển Quảng Lâm." Their word for 'person, human' is p'xinh, which is also a name for Bit (Psing).

Phonology
Nguyen (1975:431) lists the following Quang Lam complex consonant onsets in Vietnamese orthography: s'n, p'x, p's, p'k', p'r, th'l, chơr, s'ch, s'i, k'r, k'ch, m'r, l'm, r'v, d'd, r'l.
