Rade (Rhade; Rade: klei Êđê; Vietnamese: tiếng Ê-đê or tiếng Ê Đê) is an Austronesian language of southern Vietnam. There may be some speakers in Cambodia. It is a member of the Chamic subgroup, and is closely related to the Cham language of central Vietnam.^[2]

Đoàn Văn Phúc (1998:24)^[3] lists nine dialects of Rade. They are spoken mostly in Đắk Lắk Province in the Central Highlands region of Vietnam.

• Kpă: spoken throughout Buôn Ma Thuột
• Krung: spoken in Ea H'leo and Krông Năng; some Krung also live among the Jarai in Gia Lai Province
• Adham: spoken in Krông Buk, Krông Năng, and Ea H'leo
• Ktul: spoken in Krông Bông and the southern part of Krông Pắk
• Drao (Kơdrao): spoken in M'Đrăk (in the townships of Krông Jing, Cư M'Ta, and Ea Trang)
• Blô: spoken in M'Đrăk (small population)
• Êpan: spoken in M'Đrăk (small population)
• Mdhur: spoken in Ea Kar and M'Đrăk; also in Gia Lai Province and Phu Yen Province
• Bih: spoken in Krông Ana and in the southern part of Buôn Ma Thuột

Bih, which has about 1,000 speakers, may be a separate language.^[4] Tam Nguyen (2015) reported that there are only 10 speakers of Bih out of an ethnic population of about 400 people.^[5]

A patrilineal Rade subgroup known as the Hmok or Hmok Pai is found in the Buôn Ma Thuột area (Phạm 2005:212).^[6]

Đoàn Văn Phúc (1998:23)^[3] provides the following classification for the Rade dialects. Đoàn (1998) also provides a 1,000-word vocabulary list for all of the nine Rade dialects.

  • Area 1.1: Krung, Kpă, Adham
  • Area 1.2: Drao. Êpan, Ktul
  • Blô (mixture of areas 1.1 and 1.2, as well as Mdhur)
