|Region||Jinxiu Yao Autonomous County, Guangxi|
Lakkia speakers are thought to have migrated from further east, possibly from the Biao-speaking areas of northwestern Guangdong province (L.-Thongkum 1992). Today, they live mostly in the Dayaoshan (Chinese: 大瑶山; literally: "Big Yao Mountain") region of Jinxiu County.
Lakkia people are also known as the Cháshān Yáo 茶山瑶, meaning "Tea Mountain Yao", since they were traditionally considered by neighboring peoples to be ethnic Yao people. The name Lakkia is an autonym (self-designated name) that means "mountain people". All Lakkia dialects have 5 tones.
There is currently no consensus on the classification of Lakkia within the Kra–Dai family. Solnit (1988) and Hansell (1988) classify Lakkia as a sister of the Kam–Sui branch. However, L.-Thongkum (1992) considers Lakkia to be most closely related to the Tai branch, based on the large number of shared lexical items.
Dialects of Lakkia include (L.-Thongkum 1992):
- Jintian 金田
- Liula 六拉
- Jinxiu 金秀
- Lingzu 岭祖
- Changdong 长峒
The Lingzu dialect still preserves /kl-/ initial clusters, which corresponds to /kj-/ in most other dialects (L.-Thongkum 1992). Additionally, Changdong 长洞 and Jintian 金田 tone /51/ corresponds to Jinxiu 金秀 tone /231/. Also, L.-Thongkum (1992) reports that Jintian 金田 is a less conservative dialect.
