Oi language

Oi (Oy, Oey; also known as The, Thang Ong, Sok) is an Austroasiatic dialect cluster of Attapeu Province, southern Laos. The dominant variety is Oy proper, with 11,000 speakers who are 80% monolinguals. The Jeng (Cheng) speak the same language but are ethnically distinct (Sidwell 2003). Speakers follow traditional religions.

Distribution
Some locations where Oi is spoken in include (Sidwell 2003:26): The Jeng live mostly along the banks of the Sekaman River, in and around Ban Fandeng (Phandɛŋ).
 * Ban Sok, 40 km north of Attapeu
 * Ban Lagnao, 10 km northwest of Attapeu
 * Ban Inthi, 25 km southwest of Attapeu; speakers claim to have migrated from the Bolaven Plateau about 80 years ago, around the time of the Ong Kommandam Rebellion.
